vector

• 反转

  方法一：使用vector自带的反转迭代器reverse_iterator,rbegin(),rend()

vector<int>::reverse_iterator riter;

for (riter=arrayInt.rbegin();riter!=arrayInt.rend();riter++)

{

    arrayRever.push_back(*riter);

}

   

方法二：使用<algorthm>中的reverse()

arrayRever=arrayInt;

reverse(arrayRever.begin(),arrayRever.end());
