this is my program, it works fine when asking for inputs, but as soon as i press enter for the output the window just dissapers.

Code:
#include<stdio.h>
main()
{int bno;
 float sv,tax;

clrscr();
 printf("\n\n\t Enter Bill Number:");
 scanf("%d",&bno);
 printf("\n\n\t Enter Sale Value:");
 scanf("%f",&sv);

if(sv<=100000)
...
