C program to find Fibonacci series of a number (using ARRAY)

#include<stdio.h>
#include<conio.h>
main()
{

    int i,n;
    long int arr[40];

    printf("Enter the number range: ");
    scanf("%d",&n);

    arr[0]=0;
    arr[1]=1;

    for(i=2;i<n;i++){
         arr[i] = arr[i-1] + arr[i-2];
    }

    printf("Fibonacci series is: ");
    for(i=0;i<n;i++)
         printf("%ld ",arr[i]);
 
getch();   
return 0;
}



OUTPUT:

Enter the number range: 8

Fibonacci series is: 0 1 1 2 3 5 8 13
