Why C?

If programming languages were a family tree, C would be near the root. Created by Dennis Ritchie at Bell Labs in 1972, it's still, half a century later, one of the most-used languages alive — and the foundation nearly everything else stands on.

The language beneath the languages

Look at what's written in C:

• Operating systems — Linux, Windows, and macOS kernels are largely C
• Other languages — Python, Ruby, and PHP's main interpreters are C programs
• Databases, embedded devices, your car, your microwave — C, C, C

When your Python runs print(), C code ultimately does the work. Learning C means understanding the machinery under every abstraction.

Close to the metal

C gives you almost nothing for free — and that's the lesson. No automatic memory management, no built-in strings-that-just-work. You manage memory yourself (Camp 4's pointers). In return you get:

• Speed — C code runs about as fast as software can
• Control — you decide exactly what the machine does
• Understanding — concepts other languages hide, C makes you see

First taste

Every line earns its place, and you'll understand all of them next lesson. (Runs in a cloud sandbox — the pause is real compilation.)

What's next

Compile and run your first C program — and decode every symbol in it.
