C program to Print a Non-Fibonacci series

Write a C program to generate non-fibonacci series to given Limit:

#include<stdio.h>
#include<conio.h>
main()
{
 int n,a,b,c,d,x;
 a=0;
 b=1;
 c=0;
 printf("Enter the upper range of the series:");
 scanf("%d",&n);
 while(c<=n)
 {
  c=a+b;
  a=b;
  b=c;
  d=a+b;
  for(x=c+1;x<d;x++)
  {
   if(x<=n)
    printf("%d",x);
   else
    break;
  }
 }
 getch();
}


I hope this code was useful for u!!
