C Program to find Multiplication using Pointers

C Program to calculate multiplication of two numbers using pointers

This c program is used to calculate the multiplication of two numbers using c pointers.

#include<stdio.h>                                                               
                                                                                
void main()
{
    int a, b, *p, *q, mul;
 
    // Reads two user inputs integer values for variable a and b.
    printf("\nEnter integer a:");
    scanf("%d", &a);
    printf("\nEnter integer b:");
    scanf("%d", &b);

    // assign address of variable a and b to integer pointers p and q.
    p = &a;
    q = &b;
 
    // performs multiplication using pointers p and q referring the address of a and b values.
    mul = *p * *q;
 
    printf("\nMultiplication of the numbers: %d", mul);
}                                                                   
                                                                                  

$ cc multiplication-using-pointer.c 
$ ./a.out 

Enter integer a:2

Enter integer b:4

Multiplication of the numbers: 8
