C++ [Help Appreciated]


bool click(char KEY[])
{
    static int n;
    if(KEY!=0)n++;
    if(n>20){n=0; return true;}
    else return false;
}

int main()
{
    if(click(key[A]))//Do something
    else if(click(key[B]))//Do something
    return 0;
}

How do I make it so that the value of "static int n" is only incremented by one instance of the click() function? I used printf to watch the value of "int n" and it was being shared by both instances of the click() function.

One solution I found that worked was by passing a separate variable to each function:


bool click(char KEY[], int &n)
{
    if(KEY!=0)n++;
    if(n>20){n=0; return true;}
    else return false;
}

int main()
{
    static int a=0, b=0;
    if(click(key[A], a));//Do something
    else if(click(key[B], b));//Do something
    return 0;
}
Again, this works but it's kind of messy. Surely there must be a better solution to this problem. As you can guess, I'm new to this.

Why are you writing bad C in Sepples?
