在Mac操作系统上无法在vscode中使用cin或cout
在Mac操作系统上无法在vscode中使用cin或cout
提问于 2020-10-11 17:32:35
Mac OS: Catalina 10.15.7
重现问题的步骤：
- 在Mac.
中安装Xcode和vs代码
- 在vs代码.
中安装c++扩展
- 创建一个名为cpp01.
的文件夹。
- 在vs代码中打开该文件夹.
- 创建一个名为cpp01.cpp的文件，并在该文件中复制以下内容。
#include <iostream>
using namespace std;
int main() {
int intYear;
cout << "Enter Year: ";
cin >> intYear;
cout << "You have entered year: " << intYear << "\n";
}- 选择“运行”->而不调试“
”
- 选择"C++ (GDB/LLDB)"
- 选择"Clang ++ -构建和调试活动文件“
终端中的预期输出(或者如果我在Windows或Linux中运行相同的程序，我应该能够在终端中看到以下输出)：
Enter Year:那我就能进入这一年了。
但是，在Mac中运行此程序时的实际输出是：
Executing task: /usr/bin/clang++ -g /Users/abc/vscode/cpp/cpp01/cpp01.cpp -o /Users/abc/vscode/cpp/cpp01/cpp01 <
Terminal will be reused by tasks, press any key to close it.然后，如果我按下终端中的任何键，它就会关闭终端。我永远也无法进入这一年。
也就是说，在Mac中运行这个程序的行为是完全不同的。
那么，如何使用“运行”->来运行程序而不进行调试呢？(注意，我可以通过命令"./programname“编译程序并在外部终端中运行它，我只是不能使用”运行而不调试“来运行它，因为我可以在Windows或Linux中这样做)
以下是一些更多的信息：

从外部控制台运行。在launch.json中：
"externalConsole"：没错，
