## Q. C Program to Print Fibonacci Series upto N terms.

Here you will find an algorithm and program in C programming language to print fibonacci series. First let us understand what fibonacci series means.

**Explanation : **The Fibonacci sequence is a sequence consisting of a series of numbers and each number is the sum of the previous two numbers. For Example :- 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, …….

## Fibonacci Series Algorithm

START Step 1->Declare variables i, a, b, nextTerm Step 2->Initialize the variables, a=0, b=1, and nextTerm = 0 Step 3->Initialize or Enter the number of terms of Fibonacci series to be printed Step 4->Repeat below steps n times -> print the value of a -> nextTerm = a + b -> a = b -> b = nextTerm STOP

# C Program to Print Fibonacci Series

#include <stdio.h> int fib(int n) { int a, b, nextTerm, i; a = 0; b = 1; for (i = 1; i <= n; ++i) { printf("%d ", a); nextTerm = a + b; a = b; b = nextTerm; } } int main () { int n = 9; fib(n); return 0; }

#### Output

0 1 1 2 3 5 8 13 21
