VSCODE Setup Environment for Competitive Programming

## VSCode Tasks for C++ Compilation and Execution

This project uses a `tasks.json` file in Visual Studio Code to streamline the process of compiling and running C++ programs. Below is a breakdown of the tasks and how to use them.

## Prerequisites

- **g++**: Ensure that `g++` is installed on your system to compile C++ programs.
  You can install it using the following command:
  ```bash
  sudo apt install g++
  ```

  • Visual Studio Code: You should have VSCode installed with the C++ extensions for syntax highlighting and better development experience.

  • input.txt: This file should exist in the same directory as your C++ file if you want to redirect input during execution.

Tasks Overview

The tasks.json provides two tasks: one for compiling the C++ code, and another for compiling and running it in one step.

1. Compile Task

  • Label: compile

  • Command: This task compiles the currently open C++ file using the following command:

    g++ -std=c++17 -o <filename without extension> <file path>
    • Input: The open C++ file in the editor.
    • Output: An executable file with the same name as the C++ source file (but without the .cpp extension).

How to Use

  1. Open your .cpp file in VSCode.
  2. Press Ctrl+Shift+B and select the compile task.
  3. The compiled executable will be created in the same directory as your source file.

2. Compile and Run Task

  • Label: compile and run

  • Command: This task compiles and then runs the program, redirecting input from input.txt and outputting to output.txt.

    g++ -std=c++17 -o <filename without extension> <file path> && ./<filename without extension> < input.txt > output.txt
    • Input: The currently open .cpp file in the editor, and input.txt if present.
    • Output: The output will be saved to output.txt in the same directory as the C++ file.

Summary

  1. Open your .cpp file in VSCode.
  2. Make sure you have an input.txt file in the same directory.
  3. Press Ctrl+Shift+B and select the compile and run task.
  4. The program will be compiled and executed, with input read from input.txt and output written to output.txt.

Notes

  • File Paths: This tasks.json file handles file paths with spaces (e.g., directories like Programming for Career), so ensure that your project files are structured correctly.
  • Input/Output Redirection: The program expects input.txt to be present for input redirection. You can modify the task for different input/output needs.

Troubleshooting

  • No such file or directory: Ensure that the paths in the input.txt and output.txt files are correct.
  • Compile Errors: Check that your C++ code does not contain syntax errors by looking at the terminal output when running the compile task.
