Recursion : C Language Tutorial

Recursion is simply a function that calls itself, its advantage is that the code we write gets short and it gets easy to solve problems.

Example1:

void display(int n)
{
cout << n << " ";
display(n-1); //It will call display but with (n-1)
return;
}

Example2:

void rec()
{
rec(); //Function calls itself
}

int main()
{
rec(); //Setting off recursion
}
