C++ algorithm Library
The <algorithm> library has many functions that allow you to modify ranges of data from data structures.
A list of useful functions in the algorithm library can be found below.
| Function | Description |
|---|---|
| adjacent_find() | Finds a pair of consecutive elements with the same value in a data range |
| all_of() | Checks if all of the elements in a data range match a condition |
| any_of() | Checks if at least one element in a data range matches a condition |
| binary_search() | An efficient algorithm for finding if a value exists in a sorted data range |
| copy() | Copies the values from a data range into a different data range |
| count() | Counts the number of times that a value occurs in a data range |
| count_if() | Counts the number of elements in a data range that match a condition |
| fill() | Writes a value into every element of a data range |
| find() | Finds the first element of a data range with a specified value |
| find_first_of() | Finds the first element of a data range which matches one of several specified values |
| find_if() | Finds the first element of a data range which matches a condition |
| find_if_not() | Finds the first element of a data range which does not match a condition |
| for_each() | Runs a function on every element in a data range |
| includes() | Checks if all of the values in a sorted data range exist in another sorted data range |
| is_permutation() | Checks if a data range is a permutation of another |
| is_sorted() | Checks if a data range is sorted |
| is_sorted_until() | Finds the position in a data range at which elements are no longer sorted |
| lower_bound() | Finds the first element at or above a specified lower bound in a sorted data range |
| max_element() | Finds the element with the highest value in a data range |
| merge() | Merges the values of two data ranges into a new data range |
| min_element() | Finds the element with the lowest value in a data range |
| none_of() | Checks if none of the elements in a data range match a condition |
| random_shuffle() | Randomly rearranges the elements in a data range |
| replace() | Replaces all occurrences of a value in a data range with a different value |
| replace_copy() | Creates a copy of a data range with all occurrences of a specified value replaced with a different value |
| replace_copy_if() | Creates a copy of a data rage where all values that match a condition are replaced with a different value |
| replace_if() | Replaces all values in a data range that match a condition with a different value |
| reverse() | Reverses the order of elements in a data range |
| reverse_copy() | Creates a copy of a data range with the elements in reverse order |
| search() | Finds a specified sequence of values in a data range |
| sort() | Sorts the values of a data range in ascending order |
| swap() | Swaps the values of two variables |
| swap_ranges() | Swaps the values of two data ranges of the same size |
| upper_bound() | Finds the first element above a specified upper bound in a sorted data range |
