so i seem to be having an issue with my code. It is a very basic program. All it does is ask you where you want to go and adjust the coordinates accordingly but i cant seem to get the integers to increase or decrease when i tell it to any suggestions? of it is written in c

#include <iostream>

using namespace std;

int main()
{
bool quit = false;

while ( !quit )
{
    char userDirect = 'n';

    int x = 0;
    int y = 0;

    cout << "Coordinates: ("<<x<<","<<y<<")" << endl; 
    cout << "Where would you like to go? (N)orth (E)ast (S)outh (W)est: " << endl;
    cout << "(Q) to Quit." << endl;
    cin >> userDirect;

        if( userDirect == 'n' || userDirect == 'N' )   x;   

        else if( userDirect == 'e' || userDirect == 'E' )   y;      

        else if( userDirect == 's' || userDirect == 'S' ) --x;

        else if( userDirect == 'w' || userDirect == 'W' ) --y;

        else if( userDirect == 'q' || userDirect == 'Q' )
        {
            cout << "Quiting... ";
            quit = true;
        }


}
}
