  2. new and delete (C++) - Wikipedia

    en.wikipedia.org/wiki/New_and_delete_(C++)

    The C++ standard library instead provides a dynamic array (collection) that can be extended or reduced in its std::vector template class. The C++ standard does not specify any relation between new / delete and the C memory allocation routines, but new and delete are typically implemented as wrappers around malloc and free. [6]

  3. C++ string handling - Wikipedia

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

    In modern standard C++, a string literal such as "hello" still denotes a NUL-terminated array of characters. [1] Using C++ classes to implement a string type offers several benefits of automated memory management and a reduced risk of out-of-bounds accesses, [2] and more intuitive syntax for string comparison and concatenation. Therefore, it ...

  5. Placement syntax - Wikipedia

    en.wikipedia.org/wiki/Placement_syntax

    In the C++ programming language, placement syntax allows programmers to explicitly specify the memory management of individual objects — i.e. their "placement" in memory. Normally, when an object is created dynamically, an allocation function is invoked in such a way that it will both allocate memory for the object, and initialize the object ...

  6. Memory corruption - Wikipedia

    en.wikipedia.org/wiki/Memory_corruption

    When the corrupted memory contents are used later in that program, it leads either to program crash or to strange and bizarre program behavior. Nearly 10% of application crashes on Windows systems are due to heap corruption. [1] Modern programming languages like C and C++ have powerful features of explicit memory management and pointer ...

  7. Comparison of programming languages (string functions)

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

    find_character(string,char) returns integer Description Returns the position of the start of the first occurrence of the character char in string. If the character is not found most of these routines return an invalid index value – -1 where indexes are 0-based, 0 where they are 1-based – or some value to be interpreted as Boolean FALSE.

  8. Smart pointer - Wikipedia

    en.wikipedia.org/wiki/Smart_pointer

    Smart pointers can facilitate intentional programming by expressing, in the type, how the memory of the referent of the pointer will be managed. For example, if a C++ function returns a pointer, there is no way to know whether the caller should delete the memory of the referent when the caller is finished with the information.

  9. Manual memory management - Wikipedia

    en.wikipedia.org/wiki/Manual_memory_management

    In computer science, manual memory management refers to the usage of manual instructions by the programmer to identify and deallocate unused objects, or garbage.Up until the mid-1990s, the majority of programming languages used in industry supported manual memory management, though garbage collection has existed since 1959, when it was introduced with Lisp.
