Help with filestreaming
closed account (48CM4iN6)
Hey guys. My project is a reservation system. My problem is in filestreaming ( i think) . My objective that I can't figure out is to show that the cottage is reserved continously. My problem is after the 1st input, it no longer shows the "Reserved" previously. How do i this?
Here's my code: (you can run it to see)

void QuitProgram();
void ResetCottages();
void Header();
class ychoice{};
class nchoice{};
class nvalidp{};
struct reserve
{
char name[100];
