Description

The variables firstNumber and secondNumber are multiplied using the 
arithmetic operator * and the product is stored in the variable result.

C/C++

/* C Program to multiply two numbers */
//Save it as MultiplyTwoNumber.c

#include<stdio.h>
int main(){

    float firstNumber, secondNumber, result;

    printf("Enter the first number : ");
    scanf("%f",&firstNumber);

    printf("Enter the second number : ");
    scanf("%f",&secondNumber);

    result = firstNumber * secondNumber;

    printf("The multiplication of %.3f and %.3f is %.3f",firstNumber,secondNumber,result);

    return 0;
}

Input:
Enter the first number : 
3.5
Enter the second number : 
1.2

Output:
The multiplication of 3.5 and 1.2 is 4.200
