First Thing First: What Is Fibonacci Series ?
Fibonacci Series is a series of numbers where the first two Fibonacci numbers are 0 and 1, and each subsequent number is the sum of the previous two. Its recurrence relation is given by Fn = Fn-1 + Fn-2.
Below are a series of Fibonacci numbers(10 numbers):
0
1
1
2
3
5
8
13
21
34
How Its Formed:
0 <– First Number (n1)
1 <– Second Number (n2)
1 <– = 1 + 0
2 <– = 1 + 1
3 <– = 2 + 1
5 <– = 3 + 2
8 <– = 5 + 3
13 <– = 8 + 5
21 <– = 13 + 8
34 <– = 21 + 13
In this tutorial, we will learn two following ways to display Fibonacci series in C programming language: 1) Using For loop 2) Using recursion. Fibonacci Series in C using loop. A simple for loop to display the series. Program prompts user for the number of terms. C program to print fibonacci series till Nth term. In this program we first take number of terms in fibonacci series as input from user. Then starting with 0 and 1 as first two terms of the fibonacci series we generate and print consecutive fibonacci numbers by adding last two terms using a for loop. In this tutorial, we will learn two following ways to display Fibonacci series in C programming language: 1) Using For loop 2) Using recursion. Fibonacci Series in C using loop. A simple for loop to display the series. Program prompts user for the number of terms and displays the series having the same number of terms. Write a C program to calculate sum of Fibonacci series up to given limit. Solution: A series in which each number is sum of its previous two numbers is known as Fibonacci series. Each number in series is called as Fibonacci number. In this program, we assume that first two Fibonacci numbers are 0 and 1. C break and continue The Fibonacci sequence is a sequence where the next term is the sum of the previous two terms. The first two terms of the Fibonacci sequence are 0 followed by 1. The Fibonacci sequence: 0, 1, 1, 2, 3, 5, 8, 13, 21.

Logic To Generate Fibonacci Series using For Loop
Fibonacci Sequence C Program
We know that the first 2 digits in Fibonacci series are 0 and 1. So we directly initialize n1 and n2 to 0 and 1 respectively and print that out before getting into For loop logic. Since we’ve already printed two Fibonacci numbers, we assign 3 to loop control variable count and iterate through the for loop till count is less than or equal to the user entered number.
Inside For loop
As per definition of Fibonacci series: “..each subsequent number is the sum of the previous two.” So we add n1 and n2 and assign the result to n3 and display the value of n3 to the console.
Next, we step forward to get next Fibonacci number in the series, so we step forward by assigning n2 value to n1 and n3 value to n2.
For loop keeps repeating above steps until the count is less than or equal to the user entered number. If the user entered limit/count is 10, then the loop executes 8 times(as we already printed the first two numbers in the Fibonacci series, that is, 0 and 1).

What is Fibonacci series?
First two numbers of the fibonacci series is 0 and 1. From 3rd number onwards, the series will be the sum of previous 2 numbers.
Fibonacci series: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, etc
