For insertion of an element constructed in place—that is, no copy or move operations are performed—see set::emplace and set::emplace_hint.Examplec++ 複製 // set_insert.cpp // compile with: /EHsc #include <set> #include <iostream> #include <string> #include <vector> using namespace ...
C++ insert struct set //Model/BookStruct.cpp #include <iostream> using namespace std; struct BookStruct { int BookIndex; long double BookId; char *BookName; char *BookTitle; bool operator < (const BookStruct &other) const { return BookIndex < other.BookIndex; } }; //Model/Util.h #...

与map不同,set中数据只能通过insert()函数进行插入。 例如: #include <stdio.h>
