An example would be the conversion of an integer value into a floating point value or its textual representation as a string, and vice versa. An example call to the printf function printf is a c standard library function that formats text and writes it to standard output The std::string class is the standard representation for a text string since c++98

The class provides some typical string operations like comparison, concatenation, find and replace, and a function for obtaining substrings
[8] the individual units making up the string are of type char.
Java syntax a snippet of java code with keywords highlighted in bold blue font the syntax of java is the set of rules defining how a java program is written and interpreted The syntax is mostly derived from c and c++ Unlike c++, java has no global functions or variables, but has data members which are also regarded as global variables. 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. See c sharp conversion operators Undue reliance on the object type (from which all other types are derived) runs the risk of defeating the purpose of the c# type system It is usually better practice to abandon object references in favour of generics, similar to templates in c++ and generics in java.
