# VSCode C/C++ File Input + Output (Code Runner) Three Way View from [this video](https://www.youtube.com/watch?v=EAR7De6Goz4)

## 0. Download Code Runner extension for VSCode

## 0.5 Open Settings in VSCode (Cmd + , ), go to `Code-runner: Executor Map`, then open settings.json

## 1. Add these two lines in settings.json of the .vscode/ folder in the directory of your .cpp file.
```json
"c":   "cd $dir && gcc $fileName -o $fileNameWithoutExt && ./$fileNameWithoutExt < input.txt > output.txt",
"cpp": "cd $dir && g++ $fileName -o $fileNameWithoutExt && ./$fileNameWithoutExt < input.txt > output.txt"
```

## 2. Place files
input.txt   ← program reads from this  
output.txt  ← program writes to this (auto-created)

Both go in the same folder as your .c/.cpp file.

## 3. Run / Stop
Run code (while focused on the .cpp file):  
Ctrl + Option + N  

Terminate code:  
Ctrl + Option + M

## 4. After running
Open output.txt to see all program output.
