list容器&迭代器应用

 1.

#include<iostream>
#include<list>
using namespace std;
int main(){
	list<int> a={1,2,3,4,5};
	list<int> b={6,7,8,9,10};
	list<int>::iterator i;
	a.splice(a.end(),b,b.begin(),b.end());
	for(i=a.begin();i!=a.end();++i){
		cout<<*i<<" ";
	}
	return 0;
}

#include<iostream>
#include<list>
using namespace std;
int main(){
	list<int> a={1,2,3};
	list<int> b={4,5,6};
	list<int>::iterator i,j;
	i=a.begin();
	j=a.end();
	advance(i,+2);
	b.splice(b.begin(),a,i,j);
	for(i=b.begin();i!=b.end();++i){
		cout<<*i<<" ";
	}
	return 0;
}
