⚙️ Quick C++ Compile & Run Script

A handy Bash script is included to help compile and run .cpp files in one command.

📁 Script Location

scripts/run_cpp.sh

🔧 Installation

1. Make the script executable:

chmod +x scripts/run_cpp.sh

2. Move it to a global directory so it can be used anywhere:

sudo mv scripts/run_cpp.sh /usr/local/bin/run_cpp

3. Now you can run C++ files from any location like this:

run_cpp main.cpp

---

📌 Script Features

• Uses g++ with -std=c++17
• Compiles file to a .out executable
• Runs the program automatically after successful compilation
• Displays useful errors if the file is missing or fails to compile

💻 Example

run_cpp basics/hello.cpp

Sample output:

Compiling basics/hello.cpp -> basics/hello.out
Running basics/hello.out...
-------------------------------
Hello, world!

🧩 Requirements

• Ubuntu or Debian-based Linux system

• g++ installed:

  sudo apt update && sudo apt install g++
