Quick Setup Guide

Step 1: Install Compiler

# macOS
xcode-select --install

# Linux
sudo apt install build-essential git

# Windows (in WSL2)
sudo apt update && sudo apt install build-essential git

Step 2: Verify Installation

Create a test file:

// hello.c
#include <stdio.h>

int main() {
    printf("Hello, C World!\n");
    return 0;
}

Compile and run:

gcc hello.c -o hello
./hello

Step 3: Create Course Directory

mkdir -p c-course/{chapters,solutions,examples,projects}
cd c-course

Comprehensive Environment Verification

Create this verification script to test your complete setup:

#!/bin/bash
# save as verify_setup.sh
chmod +x verify_setup.sh

echo "🔍 C Programming Environment Verification"
echo "========================================"

# Test C compiler
if command -v gcc &> /dev/null; then
    echo "✅ GCC found: $(gcc --version | head -n1)"
elif command -v clang &> /dev/null; then
    echo "✅ Clang found: $(clang --version | head -n1)"
else
    echo "❌ No C compiler found. Please install gcc or clang."
    exit 1
fi

# Test compilation
echo "🔧 Testing compilation..."
cat > test.c << 'EOF'
#include <stdio.h>
#include <stdlib.h>

int main() {
    printf("C environment working!\n");
    return 0;
}
EOF

if gcc -o test test.c && ./test; then
    echo "✅ Compilation successful"
    rm -f test test.c
else
    echo "❌ Compilation failed"
    rm -f test test.c
    exit 1
fi

# Check make
if command -v make &> /dev/null; then
    echo "✅ Make found: $(make --version | head -n1)"
else
    echo "⚠️  Make not found (optional for basic course)"
fi

# Check Git
if command -v git &> /dev/null; then
    echo "✅ Git found: $(git --version)"
else
    echo "⚠️  Git not found (optional for basic course)"
fi

echo ""
echo "🚀 Environment verification complete!"
echo "You're ready to start the C Programming Course."

Run the verification:

./verify_setup.sh
