vector遍历删除特定项目和遍历删除所有项目方法

#include <iostream>
#include <string>
#include <vector>

using namespace std;

int main(void)
{
    vector<string> vecStr;

    vecStr.push_back("aaa");
    vecStr.push_back("bbb");
    vecStr.push_back("ccc");
    vecStr.push_back("ddd");
    vecStr.push_back("eee");
    vecStr.push_back("fff");
    vecStr.push_back("ggg");

    for (vector<string>::iterator iter = vecStr.begin(); iter != vecStr.end(); ++iter)
    {
        cout << *iter << endl;
    }
    cout << "-----------------------------" << endl;
    for (vector<string>::iterator iter = vecStr.begin(); iter != vecStr.end();)
    {
        if ("ggg" == *iter)
        {
            iter = vecStr.erase(iter);
        }
        else
        {
            ++iter;
        }
    }
    cout << "************************************" << endl;
    for (vector<string>::iterator iter = vecStr.begin(); iter != vecStr.end(); ++iter)
    {
        cout << *iter << endl;
    }
    return 0;
}

 

    //遍历删除所有元素
    for (vector<string>::iterator iter = vecStr.begin(); iter != vecStr.end();)
    {
        iter = vecStr.erase(iter);
    }
