unsigned == signed ?

Show all headers | View raw

int main()
{
uint x = -1;
int y = -1;
if (x == y)
printf("EQUAL");
else
printf("NOT EQUAL");
}

This code prints "EQUAL". Does this mean that bit comparison is done for 
the
equality test? If it doesn't can you give me an example that shows bit
comparison isn't done? I also wanted to know if we can assign a number to
uint & int variables such that "unit var != int var". Thanks so much
