C++基本语法---vector的使用

#include 
#include 
using namespace std;

int main()
{	
	vector vec;
	//int i = 0 ;
	
	cout << "vector原始大小:" << vec.size() << endl;
	
	for (int i = 0 ; i < 5 ; i++){
		vec.push_back(i);
	}
	
	cout << "vector push数据之后的大小:" << vec.size() << endl;
	
	for(int i = 0 ; i < vec.size() ; i++){
		cout << i << ":" << vec[i] << endl;
	}
	
	cout << "使用迭代器访问" << endl;
	vector::iterator v = vec.begin();
	while(v != vec.end()){
		cout << "v:" << *v << endl;
		v++;
	}
	
    return 0;
}
