variable nested for loops

Question

I\'m trying to figure out how I can use recursion to do n-level nested for loops. For example, if n=3, there would be 3 \'levels\'

for(z=0;z<6;z++){
   fo         


        

Answer 1

You are very vague about why you want this. For a starter a possible solution is to replace each for loop with a recursive function.

void recursiveX(int zVal, int yVal, int xVal)
{
    if(zVal+yVal+xVal == f)...
    if(xVal != 0)
        recursiveX(zVal, yVal, xVal -1);
}

void recursiveY(int zVal, int yVal)
{
    recursiveX(zVal, yVal, 6);
    if(yVal != 0)
        recursiveY(zVal, yVal-1);
}

void recursiveZ(int val)
{
    recursiveY(val, 6);
    if(val != 0)
        recursiveZ(val-1);
}
...
recursiveZ(6);

And in the end you can merge this all into one function. Nevertheless using recursion just because it is possible is never a good Idea.
