The expression ((Integer) 42). toString will convert an integer literal to string in Java while 42. ToString performs the same operation in C#. This is because the latter one is an instance call on the primitive value 42, while the former one is an instance call on an object of type java.lang.Integer.
The order in which the enumeration values are given matters. An enumerated type is an ordinal type, and the pred and succ functions will give the prior or next value of the enumeration, and ord can convert enumeration values to their integer representation. Standard Pascal does not offer a conversion from arithmetic types to enumerations, however.
Existing Eiffel software uses the string classes (such as STRING_8) from the Eiffel libraries, but Eiffel software written for .NET must use the .NET string class (System.String) in many cases, for example when calling .NET methods which expect items of the .NET type to be passed as arguments. So, the conversion of these types back and forth ...
For function that manipulate strings, modern object-oriented languages, like C# and Java have immutable strings and return a copy (in newly allocated dynamic memory), while others, like C manipulate the original string unless the programmer copies data to a new string.
Many languages have explicit pointers or references. Reference types differ from these in that the entities they refer to are always accessed via references; for example, whereas in C++ it's possible to have either a std:: string and a std:: string *, where the former is a mutable string and the latter is an explicit pointer to a mutable string (unless it's a null pointer), in Java it is only ...
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.
Gosu supports several file types: Class (.gs files) Program (.gsp files) Enhancement (*.gsx files) Template (*.gst files) In addition to standard class types Gosu supports enums, interfaces, structures, and annotations. Program files facilitate Gosu as a scripting language. For example, Gosu's Hello, World! is a simple one-line program:
Val() function which also parses a null value while converting into double (In c# Convert.ToDouble() is used to convert any object into a double type value, but which throws an exception in the case of a null value) CInt, CStr, CByte, CDbl, CBool, CDate, CLng, CCur, CObj and a wide variety of conversion functions built into the language
