Earlier quoted context omitted.

He probably thought pointers are the only kind of variables and that he needed to dereference them. I imagine something like int *a = 1, *b = 2; printf("%d\n", *a && *b); Either that or he used `%s` as a format specifier. That seems more probable. Edit: Or, as I just realised the people below me meant, printf(a && b);

Nah mate, it's just some compiler flag that I didn't turn on (don't know which. my gcc-fu is fail since it's been really a long time since I touched C)

I suck at C?

Or didn't put a format specifier, which makes sense coming from languages that don't have one in their print statements.

For Python, a common idiom is to do this: condition and truecase or falsecase See "Boolean operations" and "Conditional expressions": http://docs.python.org/3/reference/expressions.html#boolean-...
