Fundamental data types in C, such as int, char, float, and double, and teaches how to declare and initialize variables. It also covers typecasting and the importance of choosing appropriate data types for efficient programming.

Learn conditional statements (if, else, switch) to make decisions in programs and loops (for, while, do-while) to repeat actions. These structures are essential for controlling the flow of a program based on specific conditions or iterations.

Learn how to break down your code into smaller, manageable pieces by creating functions. You'll learn how to pass data to functions, get results back, and even make functions call themselves (recursion) to solve tricky problems more efficiently.

It covers how to store and manipulate collections of data with arrays and strings. You'll also dive into pointers, learning how they can be used to reference and modify data, pass arrays to functions, and work with memory more directly for efficient programming.

Learn how to manage memory while your program is running using tools like malloc and free. This allows your program to adjust memory as needed, making it more flexible and efficient, especially when dealing with large or unpredictable data.

Work with files in C, allowing you to read from and write to text or binary files. You'll learn how to open, read, write, and close files, which is essential for saving and retrieving data in your programs.
