[2016-01-19] [C + +] [About Map container]

• The map container is sorted according to the key value
• The map container has a count function, so you don't have to use find to determine if an element exists every time.
• When the map is easily indexed, if the element does not exist, it is automatically created and assigned to the default value
• If you can play this way:
• Map<string,int> MP;
• mp[' A ']++;
