What are some popular applications of the C programming language?
The C Programming language is widely used for a variety of different tasks. These include:
- Systems programming, such as implementing operating systems.
- Embedded programming, such as writing firmware for embedded computers.
- Writing compilers or libraries for other programming languages.
- Computationally expensive code that needs to run very quickly.
- End-user applications, such as web browsers.

While C is still widely used for these applications, it has some drawbacks which have led many developers to use other languages like C++, C#, Java, Perl, Rust, and many others in place of C.
Suppose that I want to do matrix math. Would C or Perl be faster? Why?
