好的，所以我最近才开始用 C++ 编程，没有其他语言的经验。
我一开始对学校项目有一个简单的想法，但不知何故，它让我在我试图创建的代码中迷失了方向。
想法如下，我想创建一个程序，首先给我一个“开始”“加载”“高分”菜单，然后当你选择其中一个时，你会得到它所说的：P 所以我从一些基本结构开始包括我在每个问题后分配给 .txt 文档的点，然后是一些 if 和 switch-case 和一个 do-while，所以如果你失败了，你可以选择重新启动。
到目前为止我已经完成的代码（距离完整还很远，但这是我所得到的）（svar 表示答案 / fraga 表示问题）：
#include <iostream>
#include <fstream>
#include <cstdlib>
using namespace std;
struct highscore{
int svar;
}
int main(){
bool fail = true;
int svar = 0, fraga;
char val;
do{
cout << " Menu" \n;
cout << " 1. Start" \n;
cout << " 2. Load" \n;
cout << " 3. Credits" \n;
cin >> val;
switch(val){
case '1':
ofstream utFil;
utFil.open("highscore.txt", ios::app);
if (!utFil){
cout << "file could not open";
exit (1);
}
cout << "WELCOME TO THE CISCO QUIZ\n" "GOOD LUCK\n \n \n" ;
cout << "how many layers are there in the OSI model?" \n "4"\n "5"\n "or 7?" \n;
cin >> fraga;
switch(fraga){
case '4':
cout << "Game Over!"\n;
cout << "Do you wish to restart? (answer with 1 for yes and 2 for no)\n";
cin >> fail;
if(fail != '1'){
fail = false;
}
break;
case '5':
cout << "Game Over!"\n;
cout << "Do you wish to restart? (answer with 1 for yes, 2 for no)\n";
cin >> fail;
if(fail != '1'){
fail = false;
}
break;
case '7':

break;

正如你所看到的，这让我感到困惑，也许你也得到了任何提示，我将非常感激
谢谢帮助：>
好的，因为我刚刚加入这个论坛，所以我还不能回答我自己的问题，所以我决定更新我的原件并再次发送代码，但这次有另一个问题。这次我无法保存分数到 .txt 文件中，它只创建一个 .txt 但保持为空 这是更新代码的样子：
#include <iostream>
#include <fstream>
#include <cstdlib>

如何让我的代码将分数保存到 .txt 文件中，而不仅仅是创建 .txt？
