some C++ question

so /prog/rammers can you tell me why this only returns
x=1 y=1
I'm trying to have it return the values that equal 133745639

heres the code:

#include <cstdlib>
#include <iostream>

using namespace std;

int main(int argc, char* argv[])
{
unsigned long int x = 1;
unsigned long int y = 1;
unsigned long int z;


while ( z != 133745639)
{
z = x * y ;

if ( z = 133745639 )
{
cout << "x=" << x << "y=" << y << endl;
}
else
x++;
}
system("PAUSE");
return 0;

}

The trouble with forcing utf8 is that some highly popular operating systems are fairly stupid regarding character encoding. You'd first have to make sure that the editors in question will reliably save utf8 text without requiring the developer to jump through hoops first, because to do otherwise would be to shoot yourself in the foot. A language whose syntax makes the normal development workflow more difficult is destined to fail. Take a history lesson from APL, lest you repeat its mistakes.
