Write a program that Sample Program with Subfunction in C++

This program demonstrates funtion calls by calling a small funtion to multiply two numbers

Source Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

#include <iostream> using namespace std; #include <conio.h> // Prototype Declarations int multiply (int num1, int num2); int main () { int multiplier; int multiplicand; cout << " Enter two integers: \n"; cin >> multiplier >> multiplicand; int Product = multiply (multiplier, multiplicand); cout << " Product of " << multiplier << " & " << multiplicand << " is " << Product ; getch(); return 0; } // main /* ============ Multiply ============== Multiply two numbers and return product. pre num1 & num2 contains values to be multiplied post product retured */ int multiply (int num1, int num2) { return (num1 * num2); }//multiply

OutPut:

Enter two integers: 17  21
Product of 17 & 21 is 357
