C++Program to Multiply Two Numbers
#include <iostream>
using namespace std;
int main() {
double num1, num2, product;
cout << "Enter two numbers: ";
// stores two floating point numbers in num1 and num2 respectively
cin >> num1 >> num2;
// performs multiplication and stores the result in product variable
product = num1 * num2;
cout << "Product = " << product;
return 0;
}
Output
Enter two numbers: 3.4
5.5
Product = 18.7
In this program, the user is asked to enter two numbers. These two numbers entered by the user are stored in variable num1 and num2 respectively.
Then, the product of num1 and num2 is evaluated and the result is stored in variable product.
Finally, the product is displayed on the screen.
