// Application that finds the average of three integers.
#include <iostream> // required to perform C++ stream I/O

using namespace std; // for accessing C++ Standard Library members

// function main begins program execution
int main()
{
   // define variables
   int number1; // stores first number input by user
   int number2; // stores second number input by user
   int number3; // stores third number input by user
      
   // prompt user for first number
   cout << "Enter the first number: ";
   cin >> number1; // read user input

   // prompt user for second number
   cout << "Enter the second number: ";
   cin >> number2; // read user input

   // prompt user for third number
   cout << "Enter the third number: ";
   cin >> number3; // read user input

   // sum number1, number2 and number3 and divide by 3
   int result = number1 + number2 + number3 / 3;
  
   // display result
   cout << "Average is: " << result << endl;

   return 0; // indicate that program ended successfully

} // end function main
