How to Install and Use Clang Compiler on Linux for C/C++

Installing Clang on Linux

• 💻 Clang is a compiler for C and C++ that can be installed on Linux via the terminal.
• 🐧 For Ubuntu/Debian systems, use the command sudo apt install clang.
• 🚀 For Fedora, the command is sudo dnf install clang. Note that package manager commands may differ across distributions.
• ✅ Verify the installation by typing clang --version in the terminal.

Compiling C Code with Clang

• 📝 Create a C file (e.g., hello.c) using a text editor like nano.
• 💡 A simple C program includes <stdio.h>, an int main() function, printf() for output, and return 0;.
• ⚙️ Compile the C file using the command clang hello.c -o hello, where -o hello specifies the output binary name.
• ▶️ Run the compiled C program with ./hello.

Compiling C++ Code with Clang++

• 📝 Create a C++ file (e.g., hello.cpp) using nano.
• 💡 A basic C++ program includes <iostream>, uses std::cout for output, and std::endl for a new line.
• 🛠️ Compile C++ code using clang++ hello.cpp -o hello_cpp, specifying the output binary name.
• ⚠️ If compilation fails, check for syntax errors in the code, such as using cout instead of see out.
• ▶️ Execute the compiled C++ program with ./hello_cpp.
