Setting Up Your C Programming Environment

Title: Setting Up Your C Programming Environment

To write and run C programs, you'll need a text editor to write your code and a C compiler to translate that code into an executable program. The most common compiler is GCC (GNU Compiler Collection).

1. Open a Text Editor or IDE

You'll need a program to write your code. Popular choices include:

Visual Studio Code (VS Code): Free, powerful, and highly recommended. It has excellent extensions for C/C++.
Notepad++ (Windows): Simple and effective for basic text editing.

Open your preferred editor.

2. Install GCC (if you don't have it)

Windows:
- The easiest way is to install MinGW-w64. Search for "MinGW-w64 download" and follow the instructions. Once installed, ensure that the bin directory of MinGW (e.g., C:\MinGW\bin or C:\Program Files\mingw-w64\x86_64-8.1.0-posix-seh-mingw-w64\mingw64\bin) is added to your system's PATH environment variable. You can test this by opening a new Command Prompt and typing gcc --version.
macOS:
- Install Xcode Command Line Tools by opening Terminal and running: xcode-select --install. This will install GCC (actually Clang, which is compatible).
Linux (Ubuntu/Debian-based):
- Open Terminal and run: sudo apt update then sudo apt install build-essential.

3. Create Your Folder Structure

It's good practice to organize your files.

Go to a location on your computer where you want to store your programming projects (e.g., your Documents folder, or create a new ProgrammingProjects folder).
Inside ProgrammingProjects, create a main folder for your subject, for example: C_Programming.
Inside C_Programming, create folders for each week, e.g., Week1, Week2.

Your structure will look something like this:

ProgrammingProjects/
└── C_Programming/
    ├── Week1/
    └── Week2/

4. Create, Write, and Save Your C Files

For each program, you'll create a new file inside the appropriate week's folder.
Open a new file in your text editor.
Type the C program code in its respective file.
Save the file with a .c extension (e.g., operators.c, max_min_three.c).

5. Execution of Program in the Command Prompt

This is how you compile and run your C programs:

Open your Command Prompt (Windows), Terminal (macOS/Linux).
Navigate to your file's directory: Use the cd command to change directories.
- Example: If your operators.c file is in C:\Users\YourUser\ProgrammingProjects\C_Programming\Week1, you would type:
  Bash
```
cd C:\Users\YourUser\ProgrammingProjects\C_Programming\Week1
```
- On macOS/Linux, it might be:
  Bash
```
cd ~/ProgrammingProjects/C_Programming/Week1
```
Compile the program: Use gcc to compile your .c file into an executable.
Bash
```
gcc your_program_name.c -o your_program_name
```
- Example for Week 1, Question 1:
  Bash
```
gcc operators.c -o operators
```
- If compilation is successful, it will create an executable file (e.g., operators.exe on Windows, or just operators on macOS/Linux) in the same directory. If there are errors, gcc will print them, and you'll need to fix your code.
Run the program: Execute the compiled program.
Bash
```
./your_program_name
```
- Example for Week 1, Question 1:
  Bash
```
./operators
```
- The program will then run, prompt for input (if any), and display its output in the command prompt.
