Fibonacci Series Generation

4. Program to generate,first n number of elements in the Fibonacci series?

Algorithm

Step 1:Start

Step 2:Declare variables n,i=0,j=1,temp,k.

Step 3:Input and read the limit of the Fibonacci series,n.

Step 4:If n==1 then

                        4.1)Print i and j.

Step 5:Else

                        5.1)Print i and j.

                        5.2)Initialize k as 2.

                        5.3)while(k<n) repeat steps a to e.

                                    a)Find temp= i+j.

                                    b)Print temp.

                                    c)Assign i=j.

                                    d)Assign j=temp.

                                    e)Increment k by 1.

                        5.4)End while.

Step 6:End if.

Step 7:Stop.

Program

#include<stdio.h>

#include<conio.h>

void main()

            {

            int n,i=0,j=1,temp,k;

            clrscr();

            printf("Enter the limit: ");

            scanf("%d",&n);

            printf("fibonacci series\n");

            if(n==1)

                        {

                        printf("%d\n%d\n",i,j);

                        }

            else

            {

            printf("%d\n%d\n",i,j);

            for(k=2;k<n;k++)

                        {

                        temp=i+j;

                        printf("%d\n",temp);

                        i=j;

                        j=temp;

                        }

            }

            getch();

            }

Output

Enter the limit:13
