我在 Ubuntu 19.04 上使用 VS 代码，我正在尝试运行一个非常简单的程序：
int main(int argc, char *argv[]) {
cout << "hello";
//some other simple stuff
我正在使用 gdb 逐步完成此代码。我的launch.json文件如下：
{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.
// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
"version": "0.2.0",
"configurations": [
{
"name": "(gdb) Launch",
"type": "cppdbg",
"request": "launch",
"program": "${workspaceFolder}/project1_debug",
"args": ["-c queue", "-f stack"],
"stopAtEntry": false,
"cwd": "${workspaceFolder}",
"environment": [],
"externalConsole": false,
"MIMode": "gdb",
"setupCommands": [
{
"description": "Enable pretty-printing for gdb",
"text": "-enable-pretty-printing",
"ignoreFailures": true
}
]
}
]
cout 下面的其他"简单东西"工作正常，只是cout不起作用。我检查了输出，问题和调试控制台，它们都没有显示任何输出。
这是我的调试控制台所说的：

Breakpoint 1, main (argc=3, argv=0x7fffffffdeb8) at project1.cpp:6

Execute debugger commands using "-exec <command>", for example "-exec info registers" will list registers in use (when GDB is the debugger)
Kill the program being debugged? (y or n) [answered Y; input not from terminal]
我不明白为什么cout不起作用。
输出在终端选项卡中，从下拉菜单中选择"数字：cppdbg：文件名"标签
我只是在launch.json中将externalConsole设置为 true，现在我在外部控制台中获得了我想要的输出(即新的 bash(
#include <iostream>，如果您在此命名空间之外，请不要忘记使用std::cout
