Calculates the average of three input values using function.
#include <iostream> using namespace std; int calc_av(int num1, int num2, int num3); //Prototype int main()/* ww w . j av a 2 s. c o m*/ { int num1, num2, num3; int avg; // Holds the return value. cout << "Please type three numbers (such as 23 54 85) "; cin >> num1 >> num2 >> num3; avg = calc_av(num1, num2, num3); cout << "\n\nThe average is " << avg; // Print the return value. return 0; } int calc_av(int num1, int num2, int num3) { int local_avg; // Holds the average for these numbers. local_avg = (num1+num2+num3) / 3; return (local_avg); }
