Short-Circuit Evaluation

In C++ the functions a, b and c given below are functionally identical. There may be good reasons to write a or b, but assuming there aren't, I prefer c.

Function a feels strangely asymmetric. Function b has more symmetry, but is rather verbose. Function c is short and to the point.

bool foo(int &); bool bar(int &); bool a(int & n) { if (foo(n)) return true; return bar(n); } bool b(int & n) { if (foo(n)) return true; if (bar(n)) return true; return false; } bool c(int & n) { return foo(n) || bar(n); }
