1. the concept of templates. We have learned overload (overloading), for overloaded functions, the check mechanism of C + + can be different from the function parameter and the owning class. Call the overloaded function correctly. For example, to

Title: Arithmetic.Idea: Using the rand ()%100 function to generate a random positive integer within 100, and also using the Random function rand ()%4 to randomly generate four random integers corresponding to the subtraction of the 0,1,2,3

In an arithmetic expression, do not use char or bool, only use them when storing characters or Boolean values. Because type char is signed on some machines and unsigned on other machines, it is particularly prone to problems if you use char for

In summary, there are three types of annotations: 1. Single-line Comment 1: //haha single-line comment2. Multi-line annotations 1: /* 2: asdfasdfasdfasdfasdf 3: * /Where multiple lines of comments are written 1: /* 2: *
