🚀 How to Run the Code Examples

Using PowerShell (Command Line)

1. Navigate to the code directory:

cd "d:\xampp\htdocs\Class\xi\C Programming\code_examples\lesson_01"

2. Compile a C program:

gcc hello_world.c -o hello_world.exe

3. Run the compiled program:

.\hello_world.exe

4. Compile and run in one command:

gcc hello_world.c -o hello_world.exe; .\hello_world.exe

Using VS Code

1. Open the project folder in VS Code
2. Open any .c file
3. Press Ctrl + F5 to compile and run
4. Or right-click and select "Run Code" (if Code Runner is installed)

Common Commands for Practice

# Navigate to different lesson folders
cd "code_examples\lesson_02"
cd "code_examples\lesson_03"

# Compile with debugging information
gcc -g program.c -o program.exe

# Run with input file (for testing)
.\program.exe < input.txt

# Check for memory leaks (with additional tools)
gcc -Wall -Wextra program.c -o program.exe

🔧 Troubleshooting Common Issues

Compilation Errors

Error: 'gcc' is not recognized

# Solution: Add gcc to PATH or reinstall MinGW
# Verify PATH: echo $env:PATH

Error: Permission denied

# Solution: Run PowerShell as Administrator
# Or change to a different directory with write permissions

Runtime Errors

Program doesn't wait for input

// Add this before scanf to clear buffer
fflush(stdin);  // Windows
// Or add a space before %c
scanf(" %c", &variable);

Infinite loops

// Always ensure loop condition changes
while (condition) {
    // Make sure condition can become false
    counter++;  // Don't forget to update variables
}

Common Beginner Mistakes

1. Missing semicolons: Every statement needs ;
2. Wrong format specifiers: Use %d for int, %f for float
3. Forgetting & in scanf: Always use &variable except for strings
4. Case sensitivity: Main ≠ main
5. Missing return 0: Always end main() with return 0;
