Dive into the fascinating world of the Fibonacci series, a cool math sequence! Ever wondered how it magically appears in code? This blog explores a special way – using recursion. Imagine a function that talks to itself, helping create the Fibonacci series. We’ll uncover this cool concept called recursion, where functions can call themselves, and we’ll learn a trick to avoid talking forever by setting a base case. Get ready for a coding adventure!
// Fibonacci series in c using recursion
#include<stdio.h>
int Fibonacci(int);
int main()
{
int num, i = 0, c;
scanf("%d",&num);
printf("Fibonacci series:\n");
for ( c = 1 ; c <= num ; c++ ){
printf("%d\n", Fibonacci(i));
i++;
}
return 0;
}
int Fibonacci(int num){
if ( num == 0 )
return 0;
else if ( num == 1 )
return 1;
else
return ( Fibonacci(num-1) + Fibonacci(num-2) );
}

Explanation of the Code:
This C program generates the Fibonacci series using recursion. The `main` function prompts the user to input the number of terms in the series (`num`).
It then iterates through a loop, printing each term of the Fibonacci series by calling the `Fibonacci` function.
The `Fibonacci` function defines the base cases (returning 0 for `num` equal to 0 and 1 for `num` equal to 1) and recursively calculates the subsequent terms.
The program continues until the desired number of terms is printed. Recursion allows for a concise and elegant implementation, breaking down the problem into smaller, solvable components.
