Simple C Program to find Fibonacci Series using For Loop

          

    Using this program a user can find a fibonacci series of entered number, so first let us understand what is Fibonacci Series. Numbers in Fibonacci Series are known as Fibonacci numbers. It is a series of number having particular pattern. For example first few numbers are:- 0,1,1,2,3,5,8,13,21...
Except first two numbers other numbers are found by adding previous two numbers. Ex: 2 is found by adding previous two numbers (1+1). see the program and observe the output, you will understand what exactly Fibonacci Series is.


Program:

 

#include<stdio.h>

#include<conio.h>

void main()

{

int c,n,t1=0,t2=1,display;

printf("Enter a number\n");

scanf("%d",&n);

printf("Fibonaci series:\n",n);

 for(c=0;c<n;c++)

 {

     if(c<=1)

      display=c;

     else

     {

        display=t1+t2;

        t1=t2;

        t2=display;

     }

     printf("%d\n",display);

 }

 getch();

}

Output:

This is the output you will get if you run the above given program to find Fibonacci Series using For Loop.
