User Input in C Programming - A Complete Guide

Master user input fundamentals in C programming through a 16-minute tutorial covering essential concepts from basic variable declarations to handling input buffers. Begin with VSCode setup before exploring variable declarations and understanding undefined behavior risks. Learn to use scanf() for different data types, manage input buffers effectively, and handle string inputs using both scanf() and fgets(). Discover how to properly use getchar() and remove newline characters from strings. Practice with hands-on examples including collecting user information like age, GPA, grades, and full names while implementing proper input validation and buffer management techniques.
