Question

If have if block like that

if(foo() || foo2() || foo3())
{
 //do some things
}

I need only one foo function to return true to execute that code.
But I have to call all of them.
Problem starts when first foo returns true. This way rest of foos (foo2 and foo3) are not being called.

I know that I can do it like that:

bool foo1 = foo1();
bool foo2 = foo2();
bool foo3 = foo3();

if(foo1 || foo2 || foo3) {}

But I have 18 foo functions and this is in few parts of my code.
Is there any trick to do it short and easy?

Answer 1

The || operator is short circuiting. You could use | instead:

if (foo1() | foo2() | foo3()) {}

But you should also consider making an array of function pointers and calling them in a loop.

and this is in few parts of my code

You should refactor your code so that you can reuse it, rather than copying and pasting the same code in many places.
