#include
void main ()
{
const int x = 5;
const int *ptrx;
ptrx = &x;
*ptrx = 10;

A. 5
B. Compilation Error
C. 10
D. Garbage value

Answer 1

Answer: Option(B) - Compilation Error.

Explanation:

#include<stdio.h>

int main()

{

const int x = 5;

const int *ptrx;

ptrx = &x; // ptrx is pointer is constant

*ptrx = 10; // Cannot be modified using ptrx.

printf("%d",x);

}

Output:

Error : assignment of read-only location 'ptrx'.

Hope it helps!
