Type the next higher prime following the number entered in the console. in c#

Create three classes the Calculation class, Conversion class and Menu Class.
The Conversion class should have the following methods.
double KMToMiles(double distance)
double MilesToKM(double distance)
double FeetToMetres(double distance)
double MetresToFeet(double distance)
double KgToPounds(double weight)
double PoundsToKg(double weight)
double CelciusToFahrenheit(double temperature)
double FahrenheightToCelcius(double temperature)
The Calculation class should have the following methods.
int SumOfSeries(int start, int end, int incr)
int SumOfArray(int data[], int size)
int ProductOfSeries(int start, int end, int incr)
int ProductOfArray(int data[], int size)
e.g. SumOfSeries(10,20,2) should produce the answer 90
Hint : 10+12+14+16+18+20
Similary ProductOfSeries(100,200,50) should produce 3,000,000
Hint : 100x150x200 = 3,000,000
The Menu class should have the following methods.
void displayMainMenu()
void displayConversionSubMenu()
void displayCalculationSubMenu()
void displayConversionLengthSubmenu()
void displayConversionWeightSubmenu()
void displayConversionTemperatureSubmenu()
The menu class methods should display the options available under each selected menu.
e.g. The displayConversionSubMenu() method should display the following.
Conversion Sub Menu

1. Sum of Series
2. Sum of Array
3. Product of Series
4. Product of Array
5. Exit
   If the user selects the sum of array option (option 2), your program should input the size of the array, get
   values to the array from the keyboard, create a Calculation type object and invoke the SumOfArray()
   method to calculate the sum of the Array element and to display it. After displaying the answer the same
   sub menu should be displayed. When the user selects Exit (option 0), you should exit from that sub menu.

statement: write a code in which user first select what type calculator they want to use. Simple or scientific and on that basis they do the calculations.
I have written the following code but it is not running. I am unable to figure out the problem. Please anybody help!!

#include <iostream>
