For example, in Python, to print the string Hello, World! followed by a newline, one only needs to write print ("Hello, World!" In contrast, the equivalent code in C++ [ 7 ] requires the import of the input/output (I/O) software library , the manual declaration of an entry point , and the explicit instruction that the output string should be ...
This is a feature of C# 9.0. Similar to in scripting languages, top-level statements removes the ceremony of having to declare the Program class with a Main method. Instead, statements can be written directly in one specific file, and that file will be the entry point of the program. Code in other files will still have to be defined in classes.
The following is a very simple C# program, a version of the classic "Hello world" example using the top-level statements feature introduced in C# 9: [111] System . Console .
In this example, the main function simply prints the text Hello, world! to the console when the program is run. This code will be executed automatically when the Dart program is run. It is important to note that while the main function is the default entry point for a Dart program, it is possible to specify a different entry point if needed.
String functions are used in computer programming languages to manipulate a string or query information about a string (some do both).. Most programming languages that have a string datatype will have some string functions although there may be other low-level ways within each language to handle strings directly.

The following code fragment depicts the process flow of a system administration script (Windows script file). Although a section marking the code appears as a comment, the diagram is in an XML CDATA section, which is technically not a comment, but serves the same purpose here. [19]
Nemerle's most notable feature is the ability to mix styles of programming that are object-oriented and functional. Programs may be structured using object-oriented concepts such as classes and namespaces, while methods can (optionally) be written in a functional style.
