Vector删除指定元素

#include<iostream>
#include<vector>
using namespace std;
int main()
{
vector<int> MyTest;
for(int i = 1; i < 101; i++)
{
MyTest.push_back(i); //循环赋初值
}
cout<<MyTest[49]<<endl;
cout<<MyTest.size()<<endl;
//找到元素位置
vector<int>::iterator idelete = MyTest.begin() + 49;
//释放元素
MyTest.erase(idelete);
cout<<MyTest[49]<<endl;
cout<<MyTest.size()<<endl;
return 0;
