How Can I Provide Standard Input to My C/C Program When Debugging in Visual Studio Code?

Writing to Standard Input in Visual Studio Code with C/C Extension

Debugging a C/C program often requires the ability to provide user input during execution. This can be challenging when using the C/C extension in Visual Studio Code, especially for Windows users since the debugging facility is unavailable.

Current Implementation:

You have successfully configured Visual Studio Code to build and run your code using a Makefile and custom tasks. However, to receive user input at runtime, you need to enable console input.

Solution:

1. Open Visual Studio Code's settings (Code -> Preferences -> Settings).
2. Scroll down to the "User Settings" section.
3. Add the following custom setting:

{
   "code-runner.runInTerminal": true
}

4. Save the settings.

Explanation:

The code-runner.runInTerminal setting launches the program in the integrated terminal. This allows for standard input while the program is running.

Example:

Consider the following helloworld.cpp program:

#include <iostream>

using namespace std;

int main() {
  string name;

  cout << "Enter your name: ";
  cin >> name;

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

  return 0;
}

When you run this program with the modified settings, the terminal will prompt you for input and pass it to the program as standard input.
