主要用到了指针、结构体、数组、链表、文件读取
由于平时用java，所以感觉自己的代码还是可以看看的，尽量用面向对象的思想去写,这也使得原本近千行代码的程序只用了不到一半的代码完成。
User.h //用户对象
struct User
{
char UserAccount[100];
char UserPassword[100];
int Money;
struct User *next;
};
UI.h //就是一个简单的菜单显示
int showMenu(char MenuItem[][20], int itemCount){
system("cls");
for (int i = 0; i < 10;i++){
printf("\n");
}
printf("***************************************************\n");
for (int i = 0; i < itemCount; i++){
printf("* ");
printf("%d.", i+1);
int Str_size = 20;
for (int j = 0; j < 10; j++){
if (MenuItem[i][j] != '\0'){
putchar(MenuItem[i][j]);
}
else{
putchar(' ');
}
}
printf(" *\n");
}
printf("***************************************************");
return 0;
}
FileContrller.h用于文件相关的操作，还有初始化
