C Pitfalls and Pitfalls

This part of the content comes from "C Traps and Pitfalls". After reading this book, I felt enlightened about the mistakes I made before.

• Vocabulary Trap
• Second syntax trap
• Three semantic traps
• four connections
• Five library functions
• Six preprocessors
• Seven Portable Defects
• Eight suggestions
