The main methods used in map are: Insert,erease,size,count,begin,end,find,clear,empty Insert Method: Inserts an element into the map, and the elements recorded in the map are usually key-value pairs, so the keys and values are encapsulated in pair

In unity, using UDP for data interaction, establish C/s mode, two clients and a service side. Two clients use different ports to send data to the server, and the server is processed and judged according to the data received to control the display of

1. Define pointers to two-dimensional arrays To facilitate the dynamic definition of rows and columns of two-dimensional arrays based on user input, variable rowsnum (rows) and colsnum (columns) are introduced. Take the example of a two-dimensional
