C++ sort排序函数用法详解
// sort algorithm example

#include
bool myfunction (int i,int j) { return (i bool myfunction2 (int i,int j) { return (i>j); }//降序排列 struct myclass { bool operator() (int i,int j) { return (i } myobject; int main () { int myints[8] = {32,71,12,45,26,80,53,33}; std::vector // using default comparison (operator <): std::sort (myvector.begin(), myvector.begin()+4); //(12 32 45 71)26 80 53 33 // using function as comp std::sort (myvector.begin()+4, myvector.end(), myfunction); // 12 32 45 71(26 33 53 80) //std::sort (myints,myints+8,myfunction);不用vector的用法 // using object as comp std::sort (myvector.begin(), myvector.end(), myobject); //(12 26 32 33 45 53 71 80) // print out content: std::cout << "myvector contains:"; for (std::vector std::cout << ' ' << *it; std::cout << ' '; return 0; }
