Using the computation by rounding method (see http://en.wikipedia.org/wiki/Fibonacci_number#Computation_by_rounding):

```Code#include <stdio.h>
#include <math.h>

double fib_closed(unsigned long n)
{
double rt5 = sqrt(5.0);
double phi = (1.0 + rt5)/2.0;

return (floor(pow(phi,n)/rt5 + 0.5));
}

int main(void)
{
unsigned long i;
for (i = 0; i < 100; i++)
{
printf("fib_closed(%lu) = %.0f
", i, fib_closed(i));
}
return 0;
}
```

Code for fibonacci series

```Code#include<stdio.h>
void main(){
int i=0,j=1,sum=0,num;
printf("enter the size of the series");
scanf("%d",&num);
while(sum<num){
printf("%d",sum);
i=j;
j=sum;
sum=i+j;
}
getch();
}
```
