Recursion in C

What Is Recursion?

Recursion is another technique that you can use if a programmer need to work on a set of values. By conceptual, it's usually easier to use iteration than recursion. However, in certain situations recursion makes more sense. Practically any loop can be converted to use recursion instead, and vice-versa.

How Recursion Related To Function?

In simple terms, recursion occurs when a function calls itself. As one would imagine, such a process would repeat indefinitely if not stopped, thus recursion needs to have some sort of end condition i.e) condition to break recursiion.

C program - Recursion

#include <stdio.h>
int rec(int count);     //function declaration
int main()
{
rec(1);
return 0;
}
int rec(int count)
{
if(count > 5)
{
return 0;
}
else
{
printf("\nThis is recursion");
count++;
rec(count);
}
return 0;
}
