Explain why

Line 138 and 140 gives different results when the address is same for both.

What do const cast actually do?

OUTPUT

CODE FOR REFERANCE

#include

using namespace std;

int main() {

const int var1 = 10;

const int* ptr1 = &var1;

cout

cout

int* ptr2 = const_cast (ptr1); // const_cast type should be same

*ptr2 = 3;

cout

cout

cout

return 0;

}

The old value of ptr1 is: 10 The old adress of ptr1 is: exglffo4 The new value of ptri is: 3 The new adress of ptr1 is: axglff04 The new value of varl is: 10
