Build real programming skills from scratch with a free C course: understand binary, memory, data types and write your first programs—earn a certificate.
Learning C is one of the fastest ways to understand what software is really doing under the hood. This beginner-friendly course takes you from foundational computer science ideas to writing and running your first C programs, while building the habits that make code reliable, readable, and efficient. Instead of treating programming as memorizing syntax, you will develop a clear mental model of how data is represented, how instructions flow through the CPU, and why those details matter when you start creating useful software.
You will start with the essentials of how computers store and work with information, including binary and hexadecimal. By connecting number systems to real files and practical computing concepts, you gain confidence reading low-level representations that often feel mysterious to newcomers. This understanding then supports more advanced topics, like why data types exist, what signed and unsigned values mean, and how overflow can produce unexpected results when your program exceeds the limits of a number’s representation.
As you progress, the course bridges concepts to hands-on practice. You will see how C programs are structured, why include statements matter, and how a simple program is built and executed. You will also learn how functions work as building blocks: how they receive arguments, return values, and help you organize logic into reusable pieces. These skills translate directly to larger projects and to other programming languages, giving you a strong base for continued learning in technology and programming.
The course also makes the relationship between programs and memory easier to grasp. You will explore key ideas about RAM, what happens to data when power is removed, and how the CPU drives execution using mechanisms like the instruction pointer. With this perspective, you will be better prepared to debug issues, reason about program behavior, and write code that behaves predictably. By the end, you will be able to run C code confidently and understand not just what to type, but why it works.

What happens to data stored in RAM when a computer is turned off?
RAM is volatile memory, so its contents are lost when power is removed.
