cross-river scheme can be as follows:Typedef char Solution; Solution sln [5];The above is actually an alias Solution for the type char, and then the Solution is used to define the sln to better reflect the semantics to increase the readability of the Code. In the previous article, the number of people on both sides of the Strait is mapped to char [4]. To enhance the semantics, you can:Typedef char PersonLayout [4]; PersonLayout oldLayout [2, 200];Note that the above is typedef char PersonLayout

corresponding basic data types are wrapped up class.These classes of data all exist in the heap,Java uses the new () statement to tell the compiler that it is dynamically created as needed at run time, so it is more flexible, but the disadvantage is that it takes more time.4.string is a special wrapper class data。 That is, you can use string str = new String ("abc"); In the form of string str = "abc" (In c
