  2. 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]

  3. Comparison of programming languages (string functions)

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

    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.

  4. Comparison of programming languages (basic instructions)

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

    The actual sizes of short int, int, and long int are available as the constants short max int, max int, and long max int etc. ^b Commonly used for characters. ^c The ALGOL 68, C and C++ languages do not specify the exact width of the integer types short , int , long , and ( C99 , C++11 ) long long , so they are implementation-dependent.

  6. Three-way comparison - Wikipedia

    en.wikipedia.org/wiki/Three-way_comparison

    In C++, any class that can be three-way compared can be a parameter to instances of std::compare_three_way, std::strong_order, std::weak_order, or std::partial_order. Since Java version 1.5, the same can be computed using the Math.signum static method if the difference can be known without computational problems such as arithmetic overflow ...

  7. C++14 - Wikipedia

    en.wikipedia.org/wiki/C++14

    C++14 allows the lookup to be done via an arbitrary type, so long as the comparison operator can compare that type with the actual key type. [16] This would allow a map from std::string to some value to compare against a const char* or any other type for which an operator< overload is available.

  9. Run-time type information - Wikipedia

    en.wikipedia.org/wiki/Run-time_type_information

    In C++, RTTI can be used to do safe typecasts using the dynamic_cast<> operator, and to manipulate type information at runtime using the typeid operator and std::type_info class. In Object Pascal, RTTI can be used to perform safe type casts with the as operator, test the class to which an object belongs with the is operator, and manipulate type ...
