    So integral types are zero-initialized, strings are initialized to empty strings, etc. The following example illustrates inserting elements into a map using the insert function and searching for a key using a map iterator and the find function:

  3. Associative array - Wikipedia

    en.wikipedia.org/wiki/Associative_array

    In computer science, an associative array, map, symbol table, or dictionary is an abstract data type that stores a collection of (key, value) pairs, such that each possible key appears at most once in the collection. In mathematical terms, an associative array is a function with finite domain. [1] It supports 'lookup', 'remove', and 'insert ...

  4. Comparison of programming languages (associative array)

    en.wikipedia.org/wiki/Comparison_of_programming...

    In Java associative arrays are implemented as "maps", which are part of the Java collections framework. Since J2SE 5.0 and the introduction of generics into Java, collections can have a type specified; for example, an associative array that maps strings to strings might be specified as follows:

  5. Comparison of Java and C++ - Wikipedia

    Allows procedural programming, functional programming (since Java 8) and generic programming (since Java 5), but strongly encourages the object-oriented programming paradigm. Includes support for creating scripting languages. Runs as native executable machine code for the target instruction set(s). Runs on a virtual machine.

    For example, performing a search on an associative container such as a map or set can be much slower using iterators than by calling member functions offered by the container itself. This is because an associative container's methods can take advantage of knowledge of the internal structure, which is opaque to algorithms using iterators.

  7. C++ - Wikipedia

    en.wikipedia.org/wiki/C++

    Function overloading allows programs to declare multiple functions having the same name but with different arguments (i.e. ad hoc polymorphism). The functions are distinguished by the number or types of their formal parameters. Thus, the same function name can refer to different functions depending on the context in which it is used.

  8. Comparison of programming languages (string functions)

    en.wikipedia.org/wiki/Comparison_of_programming...

    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. In object-oriented languages ...

  9. C++ string handling - Wikipedia

    en.wikipedia.org/wiki/C++_string_handling

    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. An std::string can be constructed from a C-style string, and a C-style string can also be obtained from one. [7]
