Unfortunately, the solution ultimately proposed doesn't work in this case: int _a = 50; int result = min(num, _a); you end up expanding to "int _a = _a;"

Unfortunately, the solution ultimately proposed doesn't work in this case: int _a = 50; int result = min(num, _a); you end up expanding to "int _a = _a;" which creates a new int _a, and assigns it to itself.
