Cool

To write “Hello World!” in the Cool programming language, you can follow these steps:
1. Open a text editor or an IDE (Integrated Development Environment) that supports the Cool programming language.
2. Write the following code:

program hello_world {
    println("Hello World!")
}

1. Save the file with a .cool extension, for example, hello_world.cool.
2. Compile the program using a Cool compiler or an IDE that supports the Cool programming language. You can find several compilers available online. For example:

– The official Cool Compiler (https://github.com/CoolCompiler/coolcompiler)
– The CoolIDE IDE (https://www.coolide.org/)
5. Run the compiled program to output “Hello World!”.

Note that if you encounter any issues or errors, make sure that your Cool compiler or IDE is properly installed and configured. You may also want to check the documentation of the language for more information on syntax and usage.
