concept Sortable = requires(T a) { { std::sort(a.begin(), a.end()) } -> std::same_as<void>; }; // 这个概念要求T类型有begin()和end()方法,并且可以用std::sort函数进行排序 标准库中提供了上百种常用的概念,放在和等头文件中。比较常用的一些有:std::sa...
Here is a more complete example of what can be done with the library: #include <algorithm> #include <cassert> #include <forward_list> #include <functional> #include <vector> #include <cpp-sort/adapters.h> #include <cpp-sort/sorters.h> int main() { struct wrapper { int value; }; ...
sort(vect.begin(), vect.end()); cout<<"after sort"<<endl; printVector(vect); return 0; }
vector<pair<string, int> > demo(m.begin(), m.end()); for (auto it = demo.begin(); it != demo.end(); ++it) { cout << (*it).first << " " << (*it).second << endl; } cout << endl; // 排序后查看效果 sort(demo.begin(), demo.end(), Special); ...
输入多行数时,直到读至输入文件末尾(EOF)为止 说明1:当读到输入结束时,cin >> a >> b返回 0,循环也结束。 说明2:在调试程序时,键盘输入的数据,用CTRL-Z(即按住CTRL键不放,再按下Z)组合作为输入结束,此谓键盘输入设备的“文件末尾”。 重点掌握 Sample Input 1 5 10 20 400 516 Sample Output 6 ...

#include<iostream>#defineN 3+2#definesum(a, b) (a + b)//宏可以带参数intmain(){std::cout <<2*N << std::endl;//输出8std::cout <<2*sum(1,2);//输出6return0;} #define是有风险的,可能导致文本被意外替换。较为推荐的做法是使用const限定符声明常量,使用函数代替带参宏。
