Mercator's projection. See {Projection}.

1. {function}.

2. In {functional programming}, the most common
{higher-order function} over lists. Map applies its first
argument to each element of its second argument (a list) and
returns the list of results.

map :: (a -> b) -> [a] -> [b]
map f [] = []
map f (x:xs) = f x : map f xs

This can be generalised to types other than lists.

  • std::map lt;Key,T,Compare,Allocator gt;::map - cppreference. net
    Example Run this code #include <iomanip> #include <iostream> #include <map> #include <string> template<typename Key, typename Value, typename Cmp> std::ostream operator <<(std::ostream os, const std::map<Key, Value, Cmp> map) { os << "{ "; for (auto comma {map size()}; const auto p : map)
  • Standard library header lt;map gt; - cppreference. net
    map (initializer_list <pair <Key, T>>, Compare = Compare (), Allocator = Allocator ()) -> map <Key, T, Compare, Allocator>; template<class InputIter, class Allocator>
  • std::unordered_map - cppreference. net
    std::unordered_map is an associative container that contains key-value pairs with unique keys Search, insertion, and removal of elements have average constant-time complexity
  • std::map lt;Key,T,Compare,Allocator gt;::~map - cppreference. net
    Destructs the map The destructors of the elements are called and the used storage is deallocated Complexity Linear in the size of * this Notes If the elements are pointers, the pointed-to objects are not destroyed
  • std::map lt;Key,T,Compare,Allocator gt;::contains - cppreference. net
    Complexity Logarithmic in the size of the container Example Run this code #include <iostream> #include <map> int main () { std::map<int, char> example {{1, 'a'}, {2, 'b'}}; for (int x : {2, 5}) if (example contains(x)) std::cout << x << ": Found\n"; else std::cout << x << ": Not found\n"; } Output: 2: Found 5: Not found
  • std::map lt;Key,T,Compare,Allocator gt;::insert - cppreference. net
    One way to check success of a hinted insert is to compare before and after Example Run this code #include <iomanip> #include <iostream> #include <map> #include <string> using namespace std::literals; template<typename It> void print_insertion_status (It it, bool success) { std::cout << "Insertion of " << it -> first
  • std::map lt;Key,T,Compare,Allocator gt;::emplace - cppreference. net
    #include <iostream> #include <string> #include <utility> #include <map> int main () { std::map<std::string, std::string> m; uses pair's move constructor m emplace(std::make_pair(std::string("a"), std::string("a"))); uses pair's converting move constructor
