C++ vector遍历demo，多种姿势任你选~
for(vector<int>::iterator it = obj.begin(); it != obj.end(); it++)
{
cout << *it << ",";
}
for(auto it = obj.begin(); it != obj.end(); it++)
{
cout << *it << ",";
}
for(int i=0;i<obj.size();i++)
{
cout<<obj[i]<<",";
}
for (auto iter : obj)
{
cout << iter << ",";
}
#include <vector>
#include <iostream>
using namespace std;
int main()
{
vector<int>obj;
for(int i=0;i<10;i++)
{
obj.push_back(i);
cout<<obj[i]<<",";
}
cout << endl << "vector size is :" << obj.size() << endl;
//iterator遍历
for(vector<int>::iterator it = obj.begin(); it != obj.end(); it++)
{
cout << *it << ",";
}
cout << endl;
//数组循环遍历
for(int i=0;i<obj.size();i++)
{
cout<<obj[i]<<",";
}
cout << endl;
//auto关键字遍历遍历
for(auto it = obj.begin(); it != obj.end(); it++)
{
cout << *it << ",";
}
cout << endl;
//基于范围的for循环
for (auto iter : obj)
{
cout << iter << ",";
}
cout << endl;
return 0;
}
