[Dev-C++] Help me with debugging pls.

Hello all,
here is my short code: 

#include <iostream.h> 
#include <stdio.h> 
#include <stdlib.h> 

int main (int argc, char *argv[]) 
{ 
    int x =3D 1000; 

    x =3D x*x; 
    cout << "Hello World!" << endl; 
    x =3D 1; 
    cout << "Press ENTER to continue... " << x <<endl; 
    getchar (); 

    return 0; 
} 

I need to watch variable x, but when I step in code while debugging each=
 line with x is skiped and no x value is displayed. Only three lines (cout=
 and getchar) are evaluated correctly. 
Some error "No symbol x in current context." is displayed in debugging=
 infos.

Does anyone know where is the problem, can you try it by yourself and write=
 me your status? I need to watch variables values while debugging because=
 otherwise it is not valuable for me. I have devcpp.exe 4.9.4.3.

Thank you very much for your help.

With best regards,

Vaclav Kremen.
