The feature of map is that all elements are automatically sorted according to the value of the element's impairment. All elements of the map are pair, with both a real value (value) and a key value (key). The first element of the pair is treated as

C + + provides a class of STL functions to retrieve elements in an array, which is simpler and more widely used are binary_search,upper_bound and Lower_bound, which are included in the header file #include, use the following:StlLower_bound and Upper_

Char in C + + is a basic type, like an int, but a string is a class that comes with a library.String This class includes a number of member functions, such as push_back (), insert (), append (), and so on, the declared variable is an object, but
