C++ 图书管理系统：按出版日期排序的图书数据结构

#include #include #include using namespace std;

struct Book { string name; string author; string date; };

bool cmp(const Book &a, const Book &b) { return a.date < b.date; }

int main() { int n; cin >> n; Book *books = new Book[n]; for(int i = 0; i < n; i++) { cin >> books[i].name >> books[i].author >> books[i].date; } sort(books, books+n, cmp); for(int i = 0; i < n; i++) { cout << books[i].name << ' ' << books[i].author << ' ' << books[i].date << endl; } delete[] books; return 0; }
