What is C? Why do we need to learn it?

What is C?

C is a general-purpose programming language that’s been around since the early 1970s. It's like the backbone of many modern languages (like Python, Java, and C++) because it's super powerful and efficient. C lets you get close to the hardware, making it great for performance-critical applications like operating systems, embedded systems, and even some games.

Why are we learning C?

  • Fundamentals: It’s like learning how to drive a manual car before switching to an automatic. If you know C, you understand how things work under the hood, like memory, pointers, and data structures.

  • Speed: C is super fast and optimized, which is why it's still used for things where performance matters.

  • Portability: Programs written in C can run on different machines with little to no modification.

  • Control: It gives you fine control over system resources (like memory), making it a beast for systems programming.

  • Gateway: Once you know C, languages like C++, Java, and even Python become easier because they have roots in C syntax.

Basically, C is that OG language that'll make you a better programmer overall, no matter what you work on in the future!
