Why the value of a doesn't change?
#include <iostream> using namespace std; int main() { const int a = 10; const int *aPtr = &a; int *aPtr2 = const_cast<int *>(aPtr); *aPtr2 = 20; cout << a << endl; cout << *aPtr << endl; cout << *aPtr2 << endl; return 0; } //Output 10 20 20 Why the value of a is not changed when the value of *aPtr and *aPtr2 is changed. They both are pointing to same memory location where a is stored. So where the value 10 is stored and where value 20 is stored?

Feichtinger Andreas I couldn't understand your answer, can you elaborate more?

But you didn't answer my question where the values 10 and 20 are stored?

Because they are constants and not variables
Try it with 'var' instead of 'const'

Int main () {
var Int a = 10;
var Int *aPtr = & a;
