for (;len>=1;len--) { for (int start=1;start<len;start++) 假如在你源码上改  程序代码：#include <iostream> #include <string> using namespace std; struct Hero { std::string name; int age; std::string sex; }; void bubble_sort( struct Hero heroArray[], size_t len ) { for( size_t i=len; i!=0; --i ) { for( size_t j=1; j!=len; ++j ) { if( heroArray[j-1].age > heroArray[j].age ) { std::swap( heroArray[j-1].name, heroArray[j].name ); std::swap( heroArray[j-1].age, heroArray[j].age ); std::swap( heroArray[j-1].sex, heroArray[j].sex ); } } } } void print_array( const struct Hero heroArray[], size_t len ) { for( size_t i=0; i!=len; ++i ) { cout << heroArray[i].name << '\n'; } } int main( void ) { struct Hero heroArray[5]= { {"刘备",23,"男"}, {"关羽",100,"男"}, {"张飞",20,"男"}, {"赵云",150,"男"}, {"貂蝉",88,"女"} }; size_t len = sizeof(heroArray)/sizeof(heroArray[0]); bubble_sort( heroArray, len ); print_array( heroArray, len ); return 0; } 假如用C++正正经经地写 程序代码：#include <string> struct Hero { std::string name; int age; std::string sex; }; #include <iostream> #include <algorithm> using namespace std; int main( void ) { struct Hero heros[] = { {"刘备", 23, "男"} , {"关羽", 100, "男"} , {"张飞", 20, "男"} , {"赵云", 150, "男"} , {"貂蝉", 88, "女"} }; sort( begin(heros), end(heros), [](const auto& a,const auto& b){return a.age<b.age;} ); for( const auto& e : heros ) cout << e.name << '\n'; } |
