Question

Example code follows:

bool result;
result = Operation1();
result &= Operation2();
result &= Operation3();
return result;

The intention is to ensure that, if any of the functions returns false, the functions that follow are not called. Is this syntax correct or do I need to do result = result && Operation2();?

Answer 1

If you mean a logical “and” rather than bitwise (I suspect so, since you’re using a bool), use short circuiting:

result = Operation1() && Operation2() && Operation3();

The functions will be evaluated left-to-right until one of them returns false, then the rest will not be evaluated.
