### fibonacci series program |  fibonacci series in c using recursion

1. #include<stdio.h>
2. int main()
3.  int n1=0,n2=1,n3,i,number;
4.  printf("Enter the number of elements:");
5.  scanf("%d",&number);
6.  printf("\n%d %d",n1,n2);
7.  for(i=2;i<number;++i)
8.  {
9.   n3=n1+n2;
10.   printf(" %d",n3);
11.   n1=n2;
12.   n2=n3;
13.  }
14.   return 0;
15.  }
Out Put
```Enter the number of elements:15
```
`0 1 1 2 3 5 8 13 21 34 55 89 144 233 377 233 377`

#### fibonacci series program | Fibonacci Series using recursion in C

1.  #include<stdio.h>
2. void printFibonacci(int n){
3.  static int n1=0,n2=1,n3;
4.    if(n>0){
5. n3 = n1 + n2;
6. n1 = n2;
7.  n2 = n3;
8. printf("%d ",n3);
9. printFibonacci(n-1);
10.  }
11. }
12. int main(){
13. int n;
14. printf("Enter the number of elements: ");
15. scanf("%d",&n);
16. printf("Fibonacci Series: ");
17. printf("%d %d ",0,1);
18. printFibonacci(n-2);
19. return 0;

Output:

`Enter the number of elements:150 1 1 2 3 5 8 13 21 34 55 89 144 233 377 `

# fibonacci series in c using function | Display Fibonacci series in C within a range using a function

Enter range: 20
The fibonacci series is:
0 1 1 2 3 5 8 13

## fibonacci series in c using for loop

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

int first = 0, second = 1, third, i, n;

printf ("Enter the length of the fibonacci series \n");
scanf ("%d", &n);

printf ("The Fibonacci series is :\n");

printf ("%d%d", first, second);

for (i = 2; i <= n; i++)

{

third = first + second;

printf ("%d ", third);

first = second;

second = third;

}

return 0;

}```

OUTPUT:

`Enter the length of the fibonacci series                                                                                               10                                                                                                                                    The Fibonacci series is :                                                                                                              011 2 3 5 8 13 21 34 55   `

### fibonacci series in c using while loop | C Program for Fibonacci Series using While Loop

```#include<stdio.h>int main(
