Is there a benefit/downside to return in an else statement?

Question

Version 1:

int abc(...)
{
    if(a || b || c))
        return 1;
    else
        return 0;
}

Version 2:

int abc(...)
{
    if(a || b || c))
        return 1;

    return 0;
}

Is there any difference? Which code is the proper one?

Answer 1

"Is there any difference?"

No.

"Which code is the proper one?"

None. They are equivalent. Note if the else isn´t explicitly needed for the context, omit it since it is redundant:

Unnecessary 'else' after 'return'. (No-else-return)

Note: The linked question is for Javascript, but it shares the same concern of yours.

Furthermore, your code could be simplified:

int abc (...)
{
    return (a || b || c);
}

If the condition is true 1, else 0 is returned.
