What is recursion? in C++

 Recursion:

A function that repeatedly calls itself.

CODE:

#include<iostream>

using namespace std;

// recursive function -> recursion..

void func() {
cout << "function call...work\n";

func(); // calls itself 

}

int main() {
func();

return 0;

}

OUTPUT:-

function call..work

function call..work

function call..work

function call..work

function call..work

...

.

..

infinite times, until a base case is declared(Smallest problem, where solution is known)..
