Hello World in Vala

Vala is a programming language that aims to bring modern programming language features to GTK+ applications without imposing any additional runtime overhead on the application. It is an object-oriented language with a syntax similar to C#, but it compiles to C code that can be linked with other C libraries.

To print "Hello, World!" in Vala, you can use the following code:

void main()
{
    print("Hello, World!\n");
}

In this code, we define a main function that takes no arguments and returns nothing (void). Inside the function, we use the print function to print the string "Hello, World!" to the standard output (stdout). The "\n" character at the end of the string is a newline character that tells print to move to the next line after printing the string.

You can compile this code using the valac compiler:

valac hello.vala

This will create an executable file called hello. You can run it by typing:

./hello

And you should see the output:

Hello, World!

Conclusion

Vala is a powerful programming language that allows you to write GTK+ applications with ease. With its syntax similar to C#, it is easy to understand and learn for programmers who are familiar with C-like languages. Its ability to compile to C code allows you to use any C library in your Vala programs, making it a versatile option for developing desktop applications.
