Pointer is a variable holding a memory address?

Answer 1

pointer is a derived datatype which contains memory addresses as their values.

program:-

#include<stdio.h>

#include<conio.h>

void main()

{

int m=5,*p;

clrscr();

p=&m;

printf("address of variable m is %p",(void *)p);

}

Answer 2

int *x,*y;

int a=14,b=10;

x=&a;

y=&b;

printf(the variable and address of the variable a is %d", a,*x);

Answer 3

Yes, the value of a pointer is an address.

For example:

int iv= 12;
int *ptr = &iv; /* now the value of 'ptr' is the address of 'iv' */

Answer 4

Yep. It's rvalue is the lvalue of another variable.

Answer 5

7. Write a program to implement linked lists using pointers.

Answer 6

Do write.

Answer 7

variable = value;
