## 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
