Program to Multiply Two Numbers

#include int main() { double a, b, product; printf("Enter two numbers: "); scanf("%lf %lf", &a, &b); // Calculating product product = a * b; // Result up to 2 decimal point is displayed using %.2lf printf("Product = %.2lf", product); return 0; }

Output

Enter two numbers: 2.4 1.12 Product = 2.69

In this program, the user is asked to enter two numbers which are stored in variables a and b respectively.

printf("Enter two numbers: "); scanf("%lf %lf", &a, &b);

Then, the product of a and b is evaluated and the result is stored in product.

product = a * b;

Finally, product is displayed on the screen using printf().

printf("Product = %.2lf", product);

Notice that, the result is rounded off to the second decimal place using %.2lf conversion character.
