How Can I Use VS Code Extensions to Handle Standard Input/Output in My C/C Programs?

Leveraging VS Code Extensions for Standard Input/Output in C/C Programs

Visual Studio Code offers a comprehensive C/C extension that enhances the development experience. However, for debugging purposes, standard input/output (I/O) functionality may pose challenges. This article explores a solution that enables writing to the standard input of a C/C program running in VS Code.

Initially, the user attempts to compile and execute the program using a series of defined tasks that leverage make and g . While these tasks facilitate successful compilation and execution, they fall short when encountering programs that require user input during runtime.

To address this issue, VS Code provides a customizable settings option that grants the necessary control over program behavior. By navigating to Code -> Preferences -> Settings and adding the following custom settings, you can activate the "runInTerminal" feature:

{
   "code-runner.runInTerminal": true
}

Once this setting is in place, running the C code triggers a terminal session within VS Code. This allows the user to interact with the standard input, providing the program with the necessary input values.

This solution alleviates the limitations of the previous debugging approach and empowers developers to execute C/C programs that rely on user input during runtime, enabling a more seamless and comprehensive development experience within Visual Studio Code.
