pointer operator

// C program to demonstrate declaration of
// pointer variables.
#include <stdio.h>
int main()
{
    int x = 10;
 
    // 1) Since there is * in declaration, ptr
    // becomes a pointer variable (a variable
    // that stores address of another variable)
    // 2) Since there is int before *, ptr is
    // pointer to an integer type variable
    int *ptr;
 
    // & operator before x is used to get address
    // of x. The address of x is assigned to ptr.
    ptr = &x;
 
    return 0;
