C program to find product two numbers using pointer

C program to find the product of two numbers using pointer

In this tutorial, we will discuss C program to find product two numbers using pointer

In the C programming language, we can use the pointer variable to find product of two numbers .

In this article, we are going to learn how to display the product of two numbers using the pointer variable.

Program 1

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int num1,num2;      //1
    int *ptr1,*ptr2;    //2
    int mul;              //3

    printf("Please enter value for num1: ");    //4
    scanf("%d",&num1);                           //5
    printf("Please enter value for num2: ");      //6
    scanf("%d",&num2);                             //7

    ptr1=&num1;                                      //8
    ptr2=&num2;

    mul=*ptr1 * *ptr2;                                 //10

    printf("Product of the two integer values is: %d",mul);  //11
    getch();
    return 0;
}

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

Please enter a value for num1: 12
Please enter a value for num2: 11
Product of the two integer values is: 132

Methods

Create two variables to store two numbers as input (num1 and num2) provided by the user.
Create two pointer variables to store the address of the numbers: num 1 and num2
Create a variable to store the sum of these numbers: sum.
Request the user to enter the first input to store variable num1
Using scanf() function, store the first input value in num1
Request the user to enter the second number to store as variable num2
Using scanf() function, store the second input value in num2.
Assign the address of variable num1 to ptr1
Assign the address of variable num2 to ptr2
Find the product of two number using their addresses – find the product of num1 and num2 using their addresses or multiply them using the pointer variables.
Finally, display result on the screen- the product of both numbers num1 and num1
