A recursive function is one which calls itself. To stop an infinite amount of calls, you need to define a base case. Your question is asking how to use them. In your C program - as with any other function - define your function first (before main() and after any included headers) Then, you will now be able to use this recursive function. The SoloLearn C tutorial outlines an example but here’s one too: void recursive(int z); int main() { recursive(8); //edit, adding a return statement return 0; } void recursive(int z) { if(z < 0) { return; } else { //do something recursive(z-1); } } It’s a pointless program but the fact recursive() calls itself means it is a recursive function. Note there is a base case/return statement to stop infinite calls.
