输入未知个数的数字,字符串

 

//以整数为例 #include <iostream> #include <vector> #include <algorithm> using namespace std; int main(){ vector<int> v; int tmp; while(cin>>tmp){ v.push_back(tmp); if(getchar() == '\n') break; } //输出 for(int val:v){ cout<<val<<endl; } return 0; } //以字符串为例 #include <iostream> #include <vector> #include <algorithm> using namespace std; int main(){ vector<string> v; string tmp; while(cin>>tmp){ v.push_back(tmp); if(getchar() == '\n') break; } //输出 for(string val:v){ cout<<val<<endl; } return 0; }
