Fibonacci Series C Program

Here is a C language program to print Fibonacci series. Fibonacci series is the series where a series of numbers in which each number ( Fibonacci number ) is the sum of the two preceding numbers.

The simplest is the series 1, 1, 2, 3, 5, 8, etc.

Print Fibonacci Series C Program

// c program to print fibonacci series
#include <stdio.h>
void fibonacci(int limit){
    int f0 = 0;
    int f1 = 1;
    int f2;
    
    printf("\nYour Fibonacci series with %d elements is...",limit+1);
    
    while(limit>1){
        if(f0 == 0 && f1 == 1){
            printf("\n%d,%d,",f0,f1);
        }
        f2 = f1 + f0;
        f0 = f1;
        f1 = f2;
        
        printf("%d,",f2);
        
        limit--;
    }
} 

int main(){
    int limit;
    
    printf("Enter series limit(1 - ∞):");
    scanf("%d",&limit);
    
    fibonacci(limit);
    
    return 0;
}

Input & Output

Enter series limit(1 - ∞):10
Your Fibonacci series with 11 elements is...
0,1,1,2,3,5,8,13,21,34,55,
