Recursive Function

[olive jewel]

Hi guys, i am trying to make a recursive function but I am having some troubles.
If the first if is true several times, calling the function herself over and over again when all of the recursive calls ends and the program reaches the second if of the first "checkFour" call, (the original one) the value of "int dist" should be the same of the arg of the first invoke, right?
For "arg of the first invoke" i mean checkFour(, , THIS ONE);

 void checkFour(int x, int y, int dist)
    {
        int xx = x;
        int yy = y;

        xx++;
        if(!vrf(x, y, xx, yy) && check(xx, yy, dist))
        {
            intt.push_back(getStr(x, y, xx, yy));
            checkFour(xx, yy, dist + 1);
        }
        xx -= 2;

        if(!vrf(x, y, xx, yy) && check(xx, yy, dist))
        {
            intt.push_back(getStr(x, y, xx, yy));
            checkFour(xx, yy, dist + 1);
        }
        xx++;
        yy++;

        if(!vrf(x, y, xx, yy) && check(xx, yy, dist))
        {
            intt.push_back(getStr(x, y, xx, yy));
            checkFour(xx, yy, dist + 1);
        }
        yy -= 2;

        if(!vrf(x, y, xx, yy) && check(xx, yy, dist))
        {
            intt.push_back(getStr(x, y, xx, yy));
            checkFour(xx, yy, dist + 1);
        }
    }```

Kind of hard to tell without more information

What do vrf and check do

You're exploring the four adjacent squares, unless you keep track of which squares you've reached already you can easily get into infinite recursion

ty for ur help but didnt get your point

How vrf or check could change the value of dist?

wdym of adjacent squares?

ohhh

u guessed what I am doing

yeah I keep tracked and thats what vrf does
