习题9.20

Exercise 9.20:

Write a program to compare whether a vector<int> contains the same elements as alist<int>.

编写程序判断一个 vector<int> 容器所包含的元素是否与一个 list<int> 容器的完全相同。

#include<iostream>#include<list>#include<vector>using namespace  std;int main(){int vecValue, listValue;vector<int> my_vec;list<int> my_list;cout <<"input vector numbers, Ctrl+z to end" <<endl;while(cin >> vecValue){my_vec.push_back(vecValue);}    cin.clear();//注意，此处要使流状态重置为有效cout<<"input list numbers, Ctrl+z to end" <<endl;while(cin >> listValue){my_list.push_back(listValue);}if(my_vec.size() != my_list.size()){cout <<"the result is different"<<endl;goto Pause;}else{vector<int> ::iterator viter = my_vec.begin();list<int> ::iterator liter = my_list.begin();while(viter != my_vec.end()){if(*viter != *liter){cout <<"the result is different"<<endl;break;}viter++;liter++;}if(viter == my_vec.end()){cout <<"the result is same"<<endl;}}Pause:  system("pause");return 0;}
