Hi. I'm new in programing and i have this program that i'm working on right now.
it's still a working progress. but when i run it and choose from the options. the program kept moving upwards. like it looses the top part of the border. like this one:

this always happens to me. i don't know why. can you check my program?
here is the code. i know it's an ugly program. but i need help.
#include<stdio.h>
#include<conio.h>
#define vid 20
#include<dos.h>

char ans;
