Fibonacci Series

Q.)  Write a C program to Fibonacci numbers less than given user number.

#include<stdio.h>

#include<conio.h>

int main( )

{

int x, y, z, num ;

printf("Enter any last Number of FIBONACCI series : ") ;

scanf("%d", &num) ;

x=0;

y=1;

while(num>=x)

    {

         z=x+y ;

         printf("%d\t", x) ;

         x=y ;

         y=z ;

     }

return 0 ;

}

                   :: OUTPUT OF ABOVE PROGRAM ::

Enter any last Number of FIBONACCI series : 60

1    1    2    3     5     8      13      21       34       55
