Overview
Before writing and running C++ programs, it is essential to set up a suitable development environment. This includes installing a C++ compiler, choosing an integrated development environment (IDE) or text editor, and understanding how to write, compile, and run a basic program.
C++ code must be compiled into machine-readable format before execution. This is typically done using compilers like GCC (GNU Compiler Collection), MSVC (Microsoft Visual C++), or Clang.
2.2 Installing a C++ Compiler
There are several popular compilers and platforms for compiling C++ code:
- GCC (GNU Compiler Collection)
- Available on Linux, Windows (via MinGW), and macOS.
- Open-source and widely used in academia and industry.
- To install on Linux:
sudo apt update
sudo apt install g++
- MinGW (Minimalist GNU for Windows)
- Provides GCC on Windows.
- After installation, the g++ command can be used from the terminal or Command Prompt.
- Microsoft Visual C++ (MSVC)
- Part of Microsoft Visual Studio.
- Ideal for Windows application development.
- Clang
- A compiler frontend for the LLVM project.
- Known for fast compilation and great diagnostics.
