Visual Studio Code:从用户获取输入 [英] Visual Studio Code: Take Input From User

问题描述

目前，我正在尝试用 Visual Studio 代码编写 C/C++ 程序.为此，我安装了两个扩展:C/C++ &C++ 智能感知

Currently, I'm trying to write C/C++ program in Visual Studio code. For this I've installed two extensions: C/C++ & C++ Intellisense

根据文档，调试工具不适用于 Windows.我已经能够通过以下任务构建和运行代码:

As per the documentation, the debugging facility is not available for windows. I've been able to build and run the code with the following tasks:

{
    "version": "0.1.0",
    "command": "cmd",
    "isShellCommand": true,
    "args": [
        "/C"
    ],
    "tasks": [
        {
            "taskName": "Makefile",
            "suppressTaskName": true,
            // Make this the default build command.
            "isBuildCommand": true,
            // Show the output window only if unrecognized errors occur.
            "showOutput": "always",
            // No args
            "args": [
                "C:/Programs/cygwin/bin/make.exe",
                "all"
            ],
            // Use the standard less compilation problem matcher.
            "problemMatcher": {
                "owner": "cpp",
                "fileLocation": [
                    "relative",
                    "${workspaceRoot}"
                ],
                "pattern": {
                    "regexp": "^(.*):(\d+):(\d+):\s+(warning|error):\s+(.*)$",
                    "file": 1,
                    "line": 2,
                    "column": 3,
                    "severity": 4,
                    "message": 5
                }
            }
        },
        {
            "taskName": "Run",
            "suppressTaskName": true,
            "isTestCommand": true,
            "args": [
                "helloworld"
            ]
        }
    ]
}

和一个简单的Makefile:

all: clean helloworld

helloworld: helloworld.cpp
    C:/Programs/cygwin/bin/g++ helloworld.cpp -o helloworld

clean:
    C:/Programs/cygwin/bin/rm -rf helloworld

但是，当程序在运行时需要一些用户输入时，就会出现问题.假设对于这个非常熟悉的 helloworld 程序.

But, the problem arises, when the programs needs some user input while running. Suppose for this very familiar helloworld program.

# include <iostream>

using namespace std;

int main ()
{
  int name;

  cin >> name;

  cout << "Hello, " << name << "!!!" << endl;

  return 0;
}

你能帮我在运行时获取用户输入吗?有一种变通方法可以将输入作为命令行参数传递.但是，对于具有复杂流程的程序来说，这是不可能的.

Can you please help me to get the user input at run time. There is a work-around to pass the input as command line arguments. But, that is not possible for programs with complex flows.

推荐答案

转到 Code ->首选项 ->设置并添加自定义设置:

Go to Code -> Preferences -> Settings and add custom settings:

{
   "code-runner.runInTerminal": true
}

最后运行你的 C++ 代码，你将能够在控制台中输入值

Finally run your c++ code and you will be able to enter values in console
