Compiled language facts for kids
A compiled programming language is a special kind of programming language that computers can understand very quickly. When you write a program using one of these languages, a tool called a compiler changes your code into instructions the computer can follow directly. These instructions are stored in a file that the computer can run super fast.

What is a Compiled Language?
Imagine you're writing a secret message in a language only you and your friend understand. A compiled programming language is a bit like that secret language. But instead of your friend, it's for a computer!
How Computers Understand Code
Computers don't understand human languages. They only understand very basic instructions, like "turn this on" or "add these numbers." This is called machine code.
When you write a program in a language like C++ or Rust, you use words and symbols that make sense to you. A special program called a compiler then takes your code and translates it entirely into machine code. This translated code is saved as an executable file. Think of it like translating a whole book into another language before anyone reads it. Once translated, the computer can read and follow the instructions in the executable file very, very quickly.
Compiled vs. Interpreted Languages
There are two main ways computers can run programs: by compiling them or by interpreting them.
- Compiled Languages: As we learned, these languages are fully translated into machine code by a compiler before they run. This makes them very fast to execute. It's like having a complete instruction manual ready to go.
- Interpreted Languages: These languages are different. Instead of translating the whole program at once, a special program called an interpreter translates and runs the code one line at a time. It's like having someone translate a sentence for you right when you need it. This can be slower for the computer to run, but it can be faster for programmers to write and test their code because they don't have to wait for the whole program to compile every time they make a small change.
Examples of Programming Languages
Many popular scripting languages are often interpreted. However, some programming languages can be either compiled or interpreted, depending on how they are used.
Here are some examples:
These languages offer flexibility, allowing developers to choose the best approach for their project.
