sequences containers:

array:连续空间,无法扩充

const long ASIZE  =   500000L;
void test_array()
{
array<long,ASIZE> c;  				
clock_t timeStart = clock();									
    for(long i=0; i< ASIZE; ++i) {
        c[i] = rand(); 
    }
	cout << "milli-seconds : " << (clock()-timeStart) << endl;	
	cout << "array.size()= " << c.size() << endl;	
	cout << "array.front()= " << c.front() << endl;	//数组第一个元素
	cout << "array.back()= " << c.back() << endl;//数组最后一个元素
	cout << "array.data()= " << c.data() << endl;//这个数组在内存起点的位置
	

vector:后面自动扩充

deque:前后都可以扩充

list:双向链表

forward_list(c++11):单向链表(节省内存)

associative containers:

内部都是红黑树实现

set/multiset:key即是value

map/multimap:key和value不同

map和set存储的是独一无二的,multiset和multimap可以放入重复的

unordered contaioners:

hashtable实现

unordered set/multiset:

unordered map/multimap:
