[RESOLVED] How does const_cast<> work?

[vincegata]

Hello,

const_cast<> supposed to "cast away const" but it does not. The output is: 1002 1001, I expect it to be 1002 1002. Could someone explain what's going on? Thx.

#include<iostream>
using namespace std;

int main(int argc, char* argv[])
{
    const int ci = 1001;
    int* i1 = const_cast<int*>(&ci);
    *i1 = 1002;
    cout << *i1 << " " << ci << endl;

    return 0;
}
