In C++, sorting string is done using two ways one with using some of the sorting techniques and another to use in-built STL Library that is provides by C++. Sorting strings is just as arranging the given strings in a specified order such as ascending order or descending order. Now let us...
在STL标准容器中,只有vector,string,deque可以使用sort的。 以vector为例: #include<iostream>#include<algorithm>#include<vector>usingnamespacestd;boolcmp(inta,intb) {returna>b; }intmain() { vector<int>vi; vi.push_back(3); vi.push_back(1); vi.push_back(2); sort(vi.begin(),vi.end(),...

当你的容器中元素时一些标准类型(int float char)或者string时,你可以直接使用这些函数模板。但如果你时自己定义的类型或者你需要按照其他方式排序,你可以有两种方法来达到效果:一种是自己写比较函数。另一种是重载类型的'<'操作赋。 #include<iostream>#include<algorithm>#include<functional>#include<vector>usingnam...
