No, it doesn't return true.
The "=" operator returns the value of the expression on its right hand side.
Therefore, the statement given above is equivalent to (as far as the if is
concerned):
if (0) {
because the "=" operator returns 0, the value on its right hand side.
That is why a statement like:
a = b = c = 2
sets all the above variables to 2. Otherwise, if it were to operate the way you
think it should, it would set "c" to 2 and "a" and "b" to "true" ;-).
Hope that clears up things for you.
