WAP A PROGRAM TO PRINT FIBONACCI SERIES UPTO NUMBER ENTERED BY THE THE USER.

#include<stdio.h>

void main()
{
int x, i;
printf(" ENTER NUMBER UPTO WHICH FIBONACI SERIES HAS TO BE GENERATED___ ");
scanf("%d", &x);
printf(" \n FIBONNACI IS = ");

for(i = 1; i < x; i++)
      fibb(i);


getch();
}
 fibb(int n)
 {
   int a;

  {
   if(n == 0)
      a = 0;
   if(n == 1)
      a = 1;
   else
      a = fibb(n-1) + fibb(n-2);

  }
  printf("%d", a);
return;
}
