Fibonnaci Number in C language

The Fibonacci Sequence is the series of numbers:

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, ...

The next number is found by adding up the two numbers before it.

if you want to search the x-th fibonacci digit you can use this code 

#include<stdio.h>

int main()
{
    int fib,a,b,c,f;
    scanf("%d",&fib);
    a=0;
    b=1;
    c=0;
    for(f=1;f<fib;f++)
    {
        c=a+b;
        a=b;
        b=c;
    }
    printf("the fibonacci %dth digit is %d",fib,c);
    return 0;
}

or you want print the all the list of fibonacci number

#include<stdio.h>

int main()
{
    int fib,a,b,c,f;
    scanf("%d",&fib);
    a=0;
    b=1;
    c=0;
    printf("%d digit of fibonnaci\n",fib);
    printf("%d %d",a,b);
    for(f=1;f<fib;f++)
    {
        c=a+b;
        a=b;
        b=c;
        printf(" %d",c);
    }
    return 0;

}

that is all from me
thank you
