Converting bool to text in C++

Question

Maybe this is a dumb question, but is there any way to convert a boolean value to a string such that 1 turns to \"true\" and 0 turns to \"false\"? I could just use an if st

Answer 1

If you decide to use macros (or are using C on a future project) you should add parenthesis around the 'b' in the macro expansion (I don't have enough points yet to edit other people's content):

#define BOOL_STR(b) ((b)?"true":"false")

This is a defensive programming technique that protects against hidden order-of-operations errors; i.e., how does this evaluate for all compilers?

1 == 2 ? "true" : "false"

compared to

(1 == 2) ? "true" : "false"
