A variable that contains the address of another variable or address of a memory location is called a pointer.
A pointer is also called a pointer variable.
A pointer variable can store address of other variables.
In C language we know that all the variables should be declared before they are used, pointer variables should be declared before they are used.
Q) W.A.P to initialize pointer to variable
#include<stdio.h>
void main()
{
int a =25,b=34,sum;
int *pa, *pb;
pa=&a;
pb=&b;
sum=*pa+*pb;
printf(“%d”,sum);
getch();
}
