Multiplication program of two floating-point numbers using function in C

Multiplication program of two floating-point numbers using function in C

In this tutorial, we will discuss the concept of Multiplication program of two floating-point numbers using function in C

In this topic, we are going to learn how to multiply two floating-point numbers using the function in C language

What is multiplication

The multiplication is a method of combining a group of equal size. The multiplication is an arithmetic operation inverse of division

It is one of the four basic operation of arithmetic calculation others being addition,subtraction,division

The multiplication of two  numbers means, it is the operation one number is combining within another using multiply(*) operator.

The answer of a multiplication operation is called as “product”

Program to multiply of two floating-point numbers in C

Program to find product of two  numbers

The program calculates the product of the given floating point numbers using function in C language

Program 1

#include <stdio.h>
#include <stdlib.h>
float mulNum(float,float);
int main()
{
    printf("find Product of floating point value\n");
   float f_No=10.5,s_No=15.9,product;
   //declaring and initializing variables
    product=mulNum(f_No,s_No);
    //calling the function and assigning the output to product variable
    printf("Product is : = %.3f",product);
//display result up to 3 decimal places
getch();
    return 0;
}
    float mulNum(float a, float b){//function definition
float result=a * b;
//multiply two numbers and store the output in variable result
return result;
//return the result to main method
    }

When the above code is executed, it produces the following result

find Product of floating point value
Product is : =166.950

Program to find product of two  numbers- Takes input from the user

The program allows the user to enter two floating-point numbers and then it calculates the multiplication of the given numbers using function in C  language

Program 2

#include <stdio.h>
#include <stdlib.h>
float mulNum(float,float);
int main()
{
    printf("find Product of floating point value\n");
   float f_No,s_No,product;
    printf("Enter first number: ");
    //ask input from the user
    scanf("%f",&f_No);
    //storing the input value in variable f_No
    printf("Enter second number: ");
    //ask input from the user
    scanf("%f",&s_No);
    //storing the input value in variable s_No
    product=mulNum(f_No,s_No);
    //calling the function and assigning the output to product variable
    printf("Product is : = %.3f",product);
//display result up to 3 decimal places
getch();
    return 0;
}
    float mulNum(float a, float b){//function definition
float result=a * b;
//multiply two numbers and store the output in variable result
return result;
//return the result to main method
    }

When the above code is executed, it produces the following result

find Product of floating point value
Enter first number: 23.23
Enter second number: 12.12
Product is : =281.548
