Solution.cpp

#include <iostream>//header file for input output function
using namespace std;//it tells the compiler to link std namespace
int find(int num1, int num2)
{//function definition
     int first, second;//variable declaration
     first = num1 * num2;
     second = first - num1 + num2;

     if (second > 50)
          num1 = first / 10;
     else
          num2 = second / 20;
     return num1 + num2;
}

int discover(int one, int two)
{//function definition
     int secret = 1;
     for (int i = one; i < two; i++)
          secret = secret * i;
     return secret;
}

int main()
{//main function
cout << find(15, 25) << endl;//function calling

cout << discover(3, 9) << endl;//function calling

cout<<find(10,10)<<\"\"<<discover(10,find(10,10))<<endl;//function calling

int x = 20,y = 10;

cout << discover(x, y) << endl;//function calling

return 0;
}

output

20160
