🖼️ Screenshot Recommendations

Program Output Screenshots

Use tools like:

• Carbon (carbon.now.sh) - Beautiful code screenshots
• Terminalizer - Animated terminal recordings
• Asciinema - Terminal session recorder

Code Snippet Styling

// ═══════════════════════════════════════════════════════════
// 📚 STACK IMPLEMENTATION - PUSH OPERATION
// ═══════════════════════════════════════════════════════════

void push(int stack[], int &top, int max, int value) {
    if (top >= max - 1) {
        cout << "❌ Stack Overflow!" << endl;
        return;
    }
    
    stack[++top] = value;
    cout << "✅ Pushed: " << value << endl;
}
