Explain Pointers in C with Examples?

Question

C Programming

Answer 1

A pointer is a variable whose value is the address of another variable, i.e., direct address of the memory location. Like any variable or constant, you must declare a pointer before using it to store any variable address.
example:
#include <stdio.h>

int main () {

int var = 20; /* actual variable declaration */
int *ip; /* pointer variable declaration */

ip = &var; /* store address of var in pointer variable*/

printf("Address of var variable: %x\n", &var );

/* address stored in pointer variable */
printf("Address stored in ip variable: %x\n", ip );

/* access the value using the pointer */
printf("Value of *ip variable: %d\n", *ip );

return 0;
}
