  2. 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 ...

  3. Array slicing - Wikipedia

    en.wikipedia.org/wiki/Array_slicing

    Common examples of array slicing are extracting a substring from a string of characters, the "ell" in "hello", extracting a row or column from a two-dimensional array, or extracting a vector from a matrix. Depending on the programming language, an array slice can be made out of non-consecutive elements.

  4. Template:Remove last word - Wikipedia

    en.wikipedia.org/wiki/Template:Remove_last_word

    This template removes the last word of the first parameter, i.e. the last non-space token after the last space. Use |1= for the first parameter if the string may contain an equals sign (=). By default, words are delimited by spaces, but the optional parameter |sep= can set the separator to any character.

  5. C string handling - Wikipedia

    en.wikipedia.org/wiki/C_string_handling

    A string is defined as a contiguous sequence of code units terminated by the first zero code unit (often called the NUL code unit). [1] This means a string cannot contain the zero code unit, as the first one seen marks the end of the string. The length of a string is the number of code units before the zero code unit. [1]

  6. Trie - Wikipedia

    en.wikipedia.org/wiki/Trie

    Insertion into trie is guided by using the character sets as indexes to the children array until the last character of the string key is reached. [14]: 733-734 Each node in the trie corresponds to one call of the radix sorting routine, as the trie structure reflects the execution of pattern of the top-down radix sort. [15]: 135

  7. Erase–remove idiom - Wikipedia

    en.wikipedia.org/wiki/Erase–remove_idiom

    It is, however, preferable to use an algorithm from the C++ Standard Library for such tasks. [1] [2] [3] The member function erase can be used to delete an element from a collection, but for containers which are based on an array, such as vector, all elements after the deleted element have to be moved forward to avoid "gaps" in the collection ...

  8. String (computer science) - Wikipedia

    en.wikipedia.org/wiki/String_(computer_science)

    This representation of an n-character string takes n + 1 space (1 for the terminator), and is thus an implicit data structure. In terminated strings, the terminating code is not an allowable character in any string. Strings with length field do not have this limitation and can also store arbitrary binary data.

  9. Null-terminated string - Wikipedia

    en.wikipedia.org/wiki/Null-terminated_string

    This allows the string to contain NUL and made finding the length need only one memory access (O(1) (constant) time), but limited string length to 255 characters. C designer Dennis Ritchie chose to follow the convention of null-termination to avoid the limitation on the length of a string and because maintaining the count seemed, in his ...
