C Get Started

Visual Studio Code (VS Code) is a popular and lightweight editor for coding. Follow these steps to install it:

• Download and install VS Code from the official website or trusted sources.
• To open VS Code quickly: Press the Windows key, type "VS Code" and hit Enter.

You need a compiler to translate your code into a working program. MinGW provides the tools to compile both C and C++ code.

1. Download MinGW

   • Open a web browser and search for "MinGW download." Download the installer (mingw-get-setup.exe).

2. Run Installer

   • Open your downloads (Ctrl + J), then double-click the installer.
   • Click Install, set the location to C:\MinGW.

3. Select Packages

   • Select mingw32-base and mingw32-gcc-g++.
   • Right-click each and select 'Mark for Installation.'

4. Apply Changes

   • Go to 'Installation' > 'Apply Changes' and wait for installation to finish.

5. Set PATH Environment Variable

   • Press Windows + S and search for "Environment Variables." Edit environment variables, select Path, click Edit, then New. Add: C:\MinGW\bin

6. Verify Installation

   • Open the command prompt (Windows + R, type cmd, press Enter).
   • Run:
     • gcc --version
     • g++ --version
     • If both display version information, your installation is complete.

To enhance coding features in VS Code, install:

• C/C++ Extension (from Microsoft)
• Code Runner (for one-click code execution)

Open Extensions panel using Ctrl + Shift + X.

• Open a project folder: Ctrl + K, then Ctrl + O.
• Create a new file: Ctrl + N.
• Save a file: Ctrl + S.
• Example file names: main.c (for C), main.cpp (for C++).

Write your program in main.c:

c Run in compiler
#include <stdio.h>

int main() {
    printf("Hello from C");
    return 0;
}

text
Hello from C

c Run in compiler
#include <iostream>
using namespace std;

int main() {
    cout << "Hello from C++";
    return 0;
}

• Open Terminal in VS Code: Ctrl + `
• Compile for C: gcc main.c -o main
• Compile for C++: g++ main.cpp -o main

• Enter ./main in the terminal to execute the program.

• Run your code: Ctrl + Alt + N
• Stop execution: Ctrl + Alt + M

• To configure the default output panel, press Ctrl + , (open settings)
  • Search: 'Code Runner: Run In Terminal'
  • Turn OFF for simple output in the Output panel.
  • To enable interactive input in the terminal, turn ON 'Run In Terminal.'
• To view output, use Ctrl + Shift + U and select 'Code Runner'.

Advanced users can set up auto-compilation:

• Open Command Palette: Ctrl + Shift + P
• Type: 'Tasks: Configure Task'
• Select: 'C/C++: g++.exe build active file'
• To build: Ctrl + Shift + B

1. Setting up VS Code and MinGW provides a complete environment for C development.
2. Configuring the PATH variable ensures the compiler runs from any terminal window.
3. VS Code extensions like C/C++ and Code Runner simplify editing and running code.
4. Manual compiling reinforces understanding of the build process.
5. Output modes in VS Code help tailor the experience for different program requirements.

1. Install VS Code and MinGW, then verify installation by compiling a sample program.
2. Create a new C file named hello.c and print "Hello, World!".
3. Compile hello.c using the terminal and run the executable.
4. Set up VS Code extensions for C programming and test one-click run.
5. Configure Code Runner’s output to use the Terminal for input-enabled programs.

1. Always verify your compiler installation with version commands before writing code.
2. Use shortcuts for faster navigation in VS Code.
3. Save files with '.c' for C or '.cpp' for C++ to ensure proper syntax detection.
4. For input and output programs, use the Terminal mode in Code Runner.
5. Configure build tasks in VS Code for automatic or one-touch compilation.
6. Regularly update extensions for improved performance and features.
