Program to implement Fibonacci series

Program to implement Fibonacci series. Comment if you need any help.

#include<stdio.h>

int fibo(int x);

main()

{

int n,i,ar[50];

printf("\n  enter the number of terms:");

scanf("%d",&n);

ar[0]=0;

for(i=1;i<n;i++)

{

ar[i]=fibo(i);

}

printf("\n");

for(i=0;i<n;i++)

printf("%d ",ar[i]);

printf("\n");

}

int fibo(int c)

{

int fib=0;

if((c==1)||(c==2))

return 1;

else

{

fib=fibo(c-1)+fibo(c-2);

return fib;

}

}
