In this tutorial, we will discuss the C program to multiply two numbers using the function
In this topic, we will learn a simple concept of how to multiply two numbers using the function in the C programming language
already we learned the same concept using the operator.
if you known click here C program to multiply two numbers
In this program, we can see step by step procedure for completion of the program.
Program 1
#include <stdio.h>
#include <stdlib.h>
int multiplyNum(int , int);//function declaration or prototype
int main()
{
int num1,num2,product;//variable declaration
printf("Enter the two number ");
scanf("%d %d",&num1,&num2);//taking two number as input from user
product=multiplyNum(num1,num2);//calling the function
//The product value (returned by the function) is stored in product variable.
printf("The product of these numbers :%d",product);
//display the product value
getch();
return 0;
}
int multiplyNum(int a, int b)//defining function based in declaration
{
int result=a*b;//find product of two numbers
//and result stored in result variable
return result;//returning result
} When the above code is compiled and executed, it produces the following results
Enter the two numbers 12 23 The product of these numbers :276
In this program, we can see step by step procedure for completion of the program.
Program 2
#include <stdio.h>
#include <stdlib.h>
float multiplyNum(float, float);
int main()
{
float num1,num2,product;
//variable declaration
printf ("Enter both numbers\n");
scanf("%f %f" ,&num1,&num2);//Taking numbers as input
product=multiplyNum(num1,num2);//calling the function
//The product value (returned by the function) is stored in product variable.
printf("The product of these numbers :%.2f",product);
//display the product value
getch();
return 0;
}
float multiplyNum(float a, float b){
//defining function based in declaration
float result=a*b;//find product of two numbers
//and result stored in result variable return result;
return result;//returning result }
}
When the above code is compiled and executed, it produces the following results
Enter both numbers 12.34 23.45 The product of these numbers:289.37
