Display Fibonacci series in C Program

In this tutorial, learn to display the Fibonacci sequence of first n numbers (entered by the user) in c programming language.

Fibonacci Series in C using loop

#include<stdio.h>
int main()
{
    int count, start = 0, second = 1, next, i;
 
    //Ask user to input number of terms 
    printf("Enter a positive number:\n");
    scanf("%d",&count);
 
    printf("First %d terms of Fibonacci series:\n",count);
    for ( i = 0 ; i < count ; i++ )
    {
       if ( i <= 1 )
          next = i;
       else
       {
          next = start + second;
          start = second;
          second = next;
       }
       printf("%d\n",next);
    }
 
    return 0;
}

Output

Enter a positive number:
