Basic Program
In this example, We will learn a simple program for pointer. Before that, You must have knowledge of the following topics.
Few Notes to remember:
*is used to access the value stored in the pointer variable&is used to store the address of the given pointer
CODE
#include <stdio.h>
int main()
{
int var = 24; // actual variable declaration
int *p;
p = &var; // storing address of int variable var in pointer p
printf("\n\nAddress of var variable is: %x \n\n", &var);
// address stored in pointer variable
printf("\n\nAddress stored in pointer variable p is: %x", p);
// access the value using the pointer variable
printf("\n\nValue of var variable or the value stored at address p is %d ", *p);
return 0;
}the output of above code is
Address of var variable is: 61ff18
Address stored in pointer variable p is: 61ff18
Value of var variable or the value stored at address p is 24
