I am integrating Speakatoo API in my project its giving me cookies error, Please any one can help me.

How to invert an image in c without external libraries...? Is it possible?

I have a web page that loads images with a modal, and at the same time is meant to inhibit image piracy by delivering a transparent overlay when a user attempts to make a screen copy of the image.
I have two php lines of image scripts which work OK independently, but when I attempt to combine them into one div, only script one will work. You can see that I've commented out the second image here (which delivers the transparent overlay) and the first image (which creates the modal) then works, and vice versa but I want to use them both at the same time. How can they be successfully combined?
It is unsuccessful if I do class="first second modal-target "

<style>
.modal-target {
    width: 390px;
    /* sets the width of the image */
    border-radius: 5px;
    cursor: pointer;
    transition: 0.3s;
}
</style>


<style>
.first {
    position: relative;
}

.second {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
}
</style>

<div class="first">
<!-- the following line delivers some images and their title to the web page -->
    <img class="modal-target" src="<?php echo $file_source; ?>" &nbsp;&nbsp;&nbsp; alt="<?php echo $title; ?>" width="400">
 <!-- the following line prevents a user from copying the image from the webpage -->
<img class="second" src='../images/Copyright.gif' alt='This image is copyright'>
</div>
<!-- there are further scripts including some php and javascript related to the modal but as the modal works OK I haven't included them here -->

Hi everyone, was wondering if maybe someone could help me. I'm new to coding and have an assignment to do. The assignment is as follows:

Write a program that lets the user enter the total rainfall for each of 12 months into an array of doubles. The program should calculate and display the total rainfall for the year, the average monthly rainfall, and the months with the highest and lowest amounts.

The program should display a list of months, sorted in order of rainfall, from highest to lowest

Input Validation: Do not accept negative numbers for monthly rainfall figures.

Include the following functions
Calculate total rainfall
Calculate the average rainfall
Find the largest amount of rainfall
Find the smallest amount of rainfall
Sort the array of rainfall data
Display the sorted data.
Display Array

what I have so fa

#include <iostream>
#include <string>
#include <iomanip>
using namespace std;

// Months, double, things needed
   const int MONTHS = 12; //Number of elements
   string name[MONTHS] = { "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December" };
   int i = 0; //Loop index
   double rainFall[MONTHS];
   double total = 0, avg = 0, highRain = 0, lowRain = 0;
   string highMonth;
   string lowMonth;

   int main()
{

   for (int i = 0; i < MONTHS; i++)
   {
      //input total rainfall for each month
      cout << "Enter rainfall for " <<name[i] << ": " << endl;
      cin >> rainFall[i];
      // input validation -- negative inputs not allowed
      while (rainFall[i] < 0)
      {
         //notify user of the error
         cout << "invalid data (negative rainfall) -- retry" << endl;
         //get new input
         cin >> rainFall[i];
      }
      //total rainfall
      total += rainFall[i];
   }

   //average rainfall
   avg = total / 12;

// Max or most rainfall
   highRain = rainFall[0];
   highMonth = name[0];

   for (int i = 1; i < MONTHS; i++)
   {
      if (rainFall[i] > highRain)
      {
         highMonth = name[i];
         highRain = rainFall[i];
      }
   }

//least or less rainfall
   lowRain = rainFall[0];
   lowMonth = name[0];

   for (int i = 1; i < MONTHS; i++)
   { 
      if (rainFall[i] < lowRain)
      {
         lowMonth = name[i];
         lowRain = rainFall[i];
      }
   }
// Display calculations --> average and total rainfall, most and least rainfall
   cout << "\n"; 
   cout << "Total rainfall: " << total << endl;
   cout << "Average: " << avg << endl;
   cout << "Most rainfall in " << highMonth << " with an amount of " << highRain << endl;
   cout << "Least rainfall in " << lowMonth << " with an amount of " << lowRain << endl;
  cout << "\n"; 

// Display a list of months, sorted in order of rainfall, from high to low
  for (i = 0; i < MONTHS; i++) {
      cout << name[i] << " " << rainFall[i] << endl;
   }

   return 0;
}

I was wondering if anyone knew how to go about sorting it? I just cant seem to wrap my head about it.
Thank you in advance!

Thank you very much if you can provide compiled Windows binaries or converted VS projects that are preferred

I'm really bad with regex. For the purposes of URI rewriting, I'm trying to figure out how to match a word one or more times in a string.

For example, I want to do something like:

string/string/string/foo/bar => foo/bar
string/string/bazbat => bazbat

Currently I have:

^string/(.*)$ => $1

and that works, but I want to make string/ work for one or more times, not just once.

Hi, I'm Arcon.

I have a problem when saving records, it saves a record and when it saves another it overlaps the first record
when reading records with its id it does not read it to me correctly

thank you

I've searched, but can't even find what to call this. Any links or code would help a ton. I want 8 main items to appear from a side-menu with 4 sub-items branching out to their right when clicked. As any sub-item is clicked, I'd like for 4 items below that to appear in an accordion-style fashion. The entire thing should never get any larger than 8x2.

Does this make sense? What am I looking for here? Thanks for any help you're able to provide.

H! I need to calculate the mean of the coverages of two types of particles that could be trapped on a square surface. They are particle #1 and particle #2. Such averages are taken after certain number of steps, for example, every 10 Monte Carlo steps, and considering a number of iterations.

The coverages mentioned before are defined as (number of particles trapped in the surface)/(number of total cells).

For illustrative purposes, the following are the steps that my simulation follows:

1. Start with the random collision of a particle on a square lattice.

2. We chose particle #1 with a given probability Y and particle #2 with probability 1 Y. ("Y is determined by the mole fraction of the particle #1 in the gas phase").

3. If the chosen particle is particle #1, we choose a site on the lattice at random. If that site is full the trial ends. Otherwise, particle #1 is trapped.

4. If the chosen particle is particle #2, we choose a site on the lattice at random. If that site is full the trial ends. Otherwise, particle #2 is trapped.

This is the code I have so far:

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <math.h>

//define the dimensions of the grid
#define MAX_X 4
#define MAX_Y 4
//define the iterations 
#define ITERATIONS (MAX_Y*MAX_X)
#define Y 0.55
FILE *data;

//define the states of a cell in grid`
typedef enum  { S_EMPTY, P1_OCCUPIED, P2_OCCUPIED, S_NONE } gstate;

// help generate random coordinate of the grid
int gridrnd(int max)
{
    return (rand() % max);
}


// generates random coordinates of the grid
int generate_coords(int* j, int* i ) 
{
    if (!i || !j)
        return 1;

    *i = gridrnd(MAX_X);
    *j = gridrnd(MAX_Y);

   // printf("(%d,%d)\n\n", *j, *i);
    return 0;
}

//function to initialize the grid as empty
void grid_init(gstate grid[MAX_Y][MAX_X])
{
    for (int j = 0; j < MAX_Y; j++) {
        for (int i = 0; i < MAX_X; i++) {
            grid[j][i] = S_EMPTY;

    printf("#availcells = %d\n\n",availcells);
    printf("#fullcells = %d\n\n",fullcells); 
    return 0;
}

I would like to calculate the mean and standard deviation of such coverages in separate functions since I will to add more interactions between the particles later on and to do not have parts of my code "spread out".my

The problem is that I'm not sure how to write properly those functions due to the content that I already have inside the for loops.

Note that such averages and standard deviations should be calculated at the end of my loops.

I'm trying to make the picturebox collide with the others.
I tried to do several things but they don't work.
I spoke to my teacher and he said I should do something like this:

PictureBox1.Left + PictureBox1.Width >= PictureBox2.Left And
         PictureBox1.Top + PictureBox1.Height >= PictureBox2.Top And
         PictureBox1.Top <= PictureBox2.Top + PictureBox2.Height And
         PictureBox1.Left <= PictureBox2.Left + PictureBox2.Width

But it didn't work either, not if it was because I didn't set the variables right or if I didn't put it in the right place.

Even after formatting cells as numbers their sum adds up to zero. How to correct this anomaly?

My program worked earlier this year before Windows 10 put and update and suddenly it doesn't work anymore. I have a separate laptop that didn't get the update and it works perfectly. Can someone please tell me what I need to do to get it to work? Ive tried everything I could think of and nothing works.

                    string[] music = Directory.GetFiles(@"C:\Users\Robert\Documents\C# stuff\Skynet\Skynet\bin\Debug\Music file", "*.mp3");// this is the original path

                    WMPLib.IWMPPlaylist Classicalplaylist = mplayer.playlistCollection.newPlaylist("classicalplaylist");
                    foreach (string file in music)
                    {
                        WMPLib.IWMPMedia media = mplayer.newMedia(file);
                        Classicalplaylist.appendItem(media);
                    }
                    mplayer.currentPlaylist = Classicalplaylist;

I am trying to print out photos from an old Windows98 computer (Dell Inspiron 2400) to a brand new HP8025e Laser printer. Our store has been operating a photo booth on this computer so I don't think I can port it to a newer version of Windows.

We had been using an old HP2200 Business Jet which did the job and had native support under W98, but that finally broke and could not obtain another.

Three questions:

1. "Properties" under W98 only offers 300dpi, I need better resolution
2. I did set the printer console to 'photo paper', but when I print the photo on photo paper, it just comes out very overdone and smeary, as if it's using 10 times too much ink. W98 properties doesn't offer a 'photo paper' option
3. The photos printed somewhat smaller on the old HP (maybe 2 1/2" by 2") whereas they print larger (maybe 4 x 3) on the new 8025, and I need them smaller so all 4 fit in a line on a 3 1/2 x 11 strip of photo paper.

I don't know if this is insoluble (HP support just told me there was no support for W98) but I thought I'd give it a try.

I have the following dataframe:

d_test = {
    'name' : ['South Beach', 'Dog', 'Bird', 'Ant', 'Big Dog', 'Beach', 'Dear', 'Cat', 'Fish', 'Dry Fish'],
    'cluster_number' : [1, 2, 3, 3, 2, 1, 4, 2, 2, 2]
}
df_test = pd.DataFrame(d_test)

I want to identify similar names in name column if those names belong to one cluster number and create unique id for them. For example South Beach and Beach belong to cluster number 1 and their similarity score is pretty high. So we associate it with unique id, say 1. Next cluster is number 2 and three entities from name column belong to this cluster: Dog, Big Dog, Cat, 'Fish' and 'Dry Fish'. Dog and Big Dog have high similarity score and their unique id will be, say 2. For Cat unique id will be, say 3. Finally for 'Fish' and 'Dry Fish' unique id will be, say 4. And so on.

I created a code for the logic above:

# pip install thefuzz
from thefuzz import fuzz

df_test = df_test.sort_values(['cluster_number', 'name'])
df_test.reset_index(drop=True, inplace=True)

df_test['id'] = 0

i = 1
for index, row in df_test.iterrows():
    row_ = row
    index_ = index

    while index_ < len(df_test) and df_test.loc[index, 'cluster_number'] == df_test.loc[index_, 'cluster_number'] and df_test.loc[index_, 'id'] == 0:
        if row['name'] == df_test.loc[index_, 'name'] or fuzz.ratio(row['name'], df_test.loc[index_, 'name']) > 50:
            df_test.loc[index_,'id'] = i
            is_i_used = True
        index_ += 1

    if is_i_used == True:
        i += 1
        is_i_used = False

Code generates expected result:

    name         cluster_number  id
0   Beach               1        1
1   South Beach         1        1
2   Big Dog             2        2
3   Cat                 2        3
4   Dog                 2        2
5   Dry Fish            2        4
6   Fish                2        4
7   Ant                 3        5
8   Bird                3        6
9   Dear                4        7

Computation runs for 210 seconds for dataframe with 1 million rows where in average each cluster has about 10 rows and max cluster size is about 200 rows. I am trying to understand how to vectorize the code.

Also thefuzz module has process function and it allows to process data at once:

from thefuzz import process
out = process.extract("Beach", df_test['name'], limit=len(df_test))

But I don't see if it can help with speeding up the code.

Design a three-bit counter using T-FFs. The counter has one input X. The counter counts odd numbers (1, 3, 5, 7) if X = 0 and counts even numbers (0, 2, 4, 6) if X = 1. If X = 1 and the current number is odd, the counter will go to the next even number. likewise, if X = 0 and the current number is even, the counter will go to the next odd.
