Set is the set, which satisfies uniqueness,The standard library set in C + + is a class template,templateclass T, // set::key_type/value_type class Compare = less, // set::key_compare/value_compare

Vector is the most basic sequential container in C + +, which can be used as an automatic variable-length array, which is easier to use than directly defining an array, but runs less efficiently than an array.The internal implementation of the

In C #, when you transfer a value type parameter to a method, you are actually using a copy of the parameter, which is to copy the original variable and then pass it to a method to let it operate. Therefore, the modification of parameters within the

The partial class is not actually a new type, but a modification of a simple property of a class, which we call "local classes". a class modified by partial can write files of a class separately in several different. cs files, but when used, these
