C Programs using Conditional and Control Statements

                        FIBBONACCI SERIES

EX.NO:2

AIM

            To write a C program to generate the Fibonacci series

ALGORITHM

Step-1: Start the program

Step-2: Enter the number

Step-3: Check the number whether the number is zero or not. If zero print Zero value. If  

             not zero go further.

Step-4: Set a loop up to the given number.

Step-5: fib=fib+a;

            a=b;

            b=c;

Step-6: Every increment in the loop prints the value of fib.

Step-7: After the execution of the loop stops the program

PROGRAM

#include<stdio.h>

main()

{

            int num,fib=0,a=0,b=1,i;

            printf(“Enter the number”);

            scanf(“%d”,&num);

            printf(“\n FIBBONACI SERIES\n”);

            if(num==0)

                        printf(“0”);

            else

            {

                        for(i=0;i<num;i++)

                        {

                                    fib=fib+a;

                                    a=b;

                                    b=fib;

                                    printf(“%d\t”,fib);

                        }}}

 OUTPUT

Enter the number 5

FIBONACCI SERIES

0 1 1 2 3

RESULT: Thus a c program to implement Fibonacci series is executed.
