C Program To Find Fibonacci Series | Learnt Hub

Hello friends, in this post today, you will learn how to find fibonacci series in C programming language.

Before starting the program, we need to know about it that what is Fibonacci Series.

Fibonacci Series:-

The first two numbers in this series are 0 and 1. To find the next number one has to combine the two previous numbers.
For example:
0,1,1,2,3,5,8,13,21,34,55..........n.

1. Operators
2. Conditions Statements
3. Loops
4. Array

In the above series we need to explained this.
First two no are 0 and 1, sum of these are 1. Next is 1 and 1, sum of these are 2. Again is 1 and 2, sum of these are 3.

Code:

#include<stdio.h> int main() { int a,b,num,sum,count=0; printf("Enter the number of term:\n "); scanf("%d",&num); printf("Enter 1st and 2nd number:\n "); scanf("%d%d",&a,&b); printf("Fibonacci series is: %d%d",a,b); while(count<num) { sum=a+b; printf("%d",sum); a=b; b=sum; count++; } return 0; }

Output:

Enter the number of term: 5

Enter 1st and 2nd number:

1

2

Fibonacci series is: 3,5,8,13,21
