得到错误“\ 342”和“\ 200”和“\ 214”错误

嗨我想写一个简单的游戏程序，但在ubuntu 13.10使用g ++和gedit得到错误'\ 342'和'\ 200'和'\ 214'。 代码是：

#include <iostream> #include <cctype> using namespace std; char all_d() { return 'D'; } int main() { bool more = true; while ( more ) { cout << "enter C to cooperate, D to defect, Q to quit\n"; char player_choice; cin >>‌ player_choice; if ( player_choice != 'C' || player_choice != 'D' || player_choice != 'Q' ) { cout << "Illegal input.\nenter an other\n"; cin >> player_choice; } char cpu_choice = all_d(); cout << "player's choice is " << player_choice << endl; cout << "cpu's choice is " << cpu_choice << endl; } if ( player_choice == 'Q' ) { cout << "Game is Over!\n"; more = false; } } 

而terminal输出是：

 IPD.cpp:18:3: error: stray '\342' in program cin >>‌ player_choice; ^ IPD.cpp:18:3: error: stray '\200' in program IPD.cpp:18:3: error: stray '\214' in program IPD.cpp: In function 'int main()': IPD.cpp:29:47: error: 'end' was not declared in this scope cout << "cpu's choice is " << cpu_choice << end; ^ IPD.cpp:32:7: error: 'player_choice' was not declared in this scope if ( player_choice == 'Q' ) ^ 

甚至试图编译这个：

 #include <iostream> using namespace std; int main() { char a; cin >>‌ a; } 

terminal又说：

• 尽pipeunixODBC已安装，但缺lesssql.h头文件
• 崇高文本3 – 编译程序并在terminal中运行
• 在Qt Creator中进入Qt源代码（在Ubuntu Linux中）
• 为什么在Ubuntu 12.04下的OpenMP比串行版本慢
• 库链接，但引用是未定义的

 a.cpp:8:2: error: stray '\342' in program cin >>‌ a; ^ a.cpp:8:2: error: stray '\200' in program a.cpp:8:2: error: stray '\214' in program 

任何人都可以帮助我？

请注意，我昨天晚上安装了Ubuntu。

 cin >>‌ a; 

 while ( more ) { cout << "enter C to cooperate, D to defect, Q to quit\n"; char player_choice; // other stuff } if ( player_choice == 'Q' ) { cout << "Game is Over!\n"; more = false; }
