Fibonacci series in c using for loop

#include<stdio.h>

int main(){

    int k,r;

    long int i=0l,j=1,f;

    //Taking maximum numbers form user

    printf("Enter the number range:");

    scanf("%d",&r);

    printf("FIBONACCI SERIES: ");

    printf("%ld %ld",i,j); //printing firts two values.

    for(k=2;k<r;k++){

         f=i+j;

         i=j;

         j=f;

         printf(" %ld",j);

    }

  

    return 0;

}

Sample output:

Enter the number range: 15

FIBONACCI SERIES: 0 1 1 2 3 5 8 13 21 34 55 89 144 233 377

Code 2:

1. Fibonacci series using array in c

2. Fibonacci series program in c language

3. Source code of Fibonacci series in c

4. Wap to print Fibonacci series in c

#include<stdio.h>

int main(){

    int i,range;

    long int arr[40];

    printf("Enter the number range: ");

    scanf("%d",&range);

    arr[0]=0;

    arr[1]=1;

    for(i=2;i<range;i++){

         arr[i] = arr[i-1] + arr[i-2];

    }

    printf("Fibonacci series is: ");

    for(i=0;i<range;i++)

         printf("%ld ",arr[i]);

  

    return 0;

}

Sample output:

Enter the number range: 20

Fibonacci series is: 0 1 1 2 3 5 8 13 21 34 55 89 144 233 377 610 987 1597 2584 4181

4. Fibonacci series in c with explanation

5. C code to generate Fibonacci series

#include<stdio.h>

int main(){

    int k=2,r;

    long int i=0l,j=1,f;

    printf("Enter the number range:");

    scanf("%d",&r);

    printf("Fibonacci series is: %ld %ld",i,j);

    while(k<r){

         f=i+j;

         i=j;

         j=f;

         printf(" %ld",j);

          k++;

    }

  

    return 0;

}

Sample output:

Enter the number range: 10

Fibonacci series is: 0 1 1 2 3 5 8 13 21 34

Code 4:

1. Sum of Fibonacci series in c

#include<stdio.h>

int main(){

    int k,r;

    long int i=0,j=1,f;

    long int sum = 1;

    printf("Enter the number range: ");

    scanf("%d",&r);

    for(k=2;k<r;k++){

         f=i+j;

         i=j;

         j=f;

         sum = sum + j;

    }

    printf("Sum of Fibonacci series is: %ld",sum);

  

    return 0;

}

Sample output:

Enter the number range: 4

Sum of Fibonacci series is: 4
