Comprehensive Collection of C Programming Examples

In this example, the product of the two floating-point numbers entered by the user will be calculated and printed on the screen.

The program multiplies two numbers

#include <stdio.h>
int main() {
　　　　double a, b, product;
　　　　printf("Enter two numbers: ");
　　　　scanf("%lf %lf", &a, &b);　　
　
　　　　//　Multiply
　　　　product = a　*　b;
　　　　//Using %.2lf shows decimal places after2The result of the bit
　　　　printf("Product = %.2lf", product);
　　　　
　　　　return 0;
}

Output result

Enter two numbers:　2.4
1.12
Product =　2.69

In this program, the user is required to input two numbers to store in variables a and b.

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

Then calculate the product of a and b, and store the result in product.

product = a　*　b;

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

Please note that the result uses %.2Round the character to two decimal places after the decimal point.
