how to scan the value of a variable by using pointer

Rajnish Tripathi 23:02

 Here in this post we will write a program in which we will scan the value of a variable by using pointer . So first we have to know that what is pointer . Pointer is a variable which store the address of  another variable . So here we will take input by using pointer.

Code:-

#include <stdio.h>
int main()
{
int i;
int *pi = &i;
printf("Enter a value\n");
scanf("%d", pi);
printf("you enter %d \n", i);
return 0;
}

Output:-

Enter a value 50
you enter 50
