한 다중 집합에서 다른 다중 집합으로의 한 위치에서 다른 위치로 다중 집합 컨테이너의 요소를 삽입하는 C++ STL의 다중 집합 insert() 함수입니다.
사용된 기능 목록:
- ms.size() =다중 집합의 크기를 반환합니다.
- ms.insert() =다중 집합에 요소를 삽입하는 데 사용됩니다.
예시 코드
#include <iostream>
#include <set>
#include <string>
#include <cstdlib>
using namespace std;
int main() {
multiset<int> ms;
multiset<int>::iterator it, it1;
int c, i;
while (1) {
cout<<"1.Size of the Multiset"<<endl;
cout<<"2.Insert Element into the Multiset"<<endl;
cout<<"3.Display Multiset"<<endl;
cout<<"4.Exit"<<endl;
cout<<"Enter your Choice: ";
cin>>c;
switch(c) {
case 1:
cout<<"Size of the Multiset: "<<ms.size()<<endl;
break;
case 2:
cout<<"Enter value to be inserted: ";
cin>>i;
if (ms.empty())
it1 = ms.insert(i);
else
it1 = ms.insert(it1, i);
break;
case 3:
cout<<"Elements of the Multiset: ";
for (it = ms.begin(); it != ms.end(); it++)
cout<<*it<<" ";
cout<<endl;
break;
case 4:
exit(1);
break;
default:
cout<<"Wrong Choice"<<endl;
}
}
return 0;
