Is there an advantage to having an ‘else’ following a block
which ends with a ‘return’ or is it simply out of habit

int foo (int a)
{
    if(a==0)
    {
        return false;
    }
    else
        if(a==1)
        {
            return true;
        }
        else
        {
        }
    return -1;
}

just curious
