is it ok to do this

instead of

int f(a) {
if(a == 3) return 1
else return 0;
}
to write

return (a == 3);
? thanks in advance

Nothing is wrong with the ternary operator yet it is not mandatory. Sometimes ternary is avoided in code that you debug, it makes it easier, and there are other reasons for not using ternary.

But I spam it like hell at every chance I get anyway.
