Given two floating numbers A and B. The task is to write a program to find the product of these two numbers. Examples:

Input: A = 2.12, B = 3.88 Output: 8.225600 Input: A = 3.78, B = 6.32 Output: 23.889601

In the below program to multiply two floating point numbers, the user is first asked to enter two floating numbers and the input is scanned using the scanf() function and stored in the variables A  and B  . Then, the variables A  and B  are multiplied using the arithmetic operator *  and the product is stored in the variable product. Below is the C program to multiply two floating point numbers: 

C




// C program to multiply two floating point numbers
#include <stdio.h>
 
int main()
{
    float A, B, product = 0.0f;
 
    // Ask user to enter the two numbers
    printf("Enter two floating numbers A and B : \n");
 
    // Read two numbers from the user || A = 2.12, B = 3.88
    scanf("%f%f", &A, &B);
 
    // Calculate the multiplication of A and B
    // using '*' operator
    product = A * B;
 
    // Print the product
    printf("Product of A and B is: %f", product);
 
    return 0;
}

Time Complexity: O(1), as we are not using any loops.

Auxiliary Space: O(1), as we are not using any extra space.
