尝试使用max_element找出数组中的最大数字时出错 [英] Error when attempting to use max_element to figure out the highest number in an array

问题描述

int a = max_element(highesthuman[0], highesthuman[2]); 
  if( win > loss)
  {
    cout << "You won " << (win-loss) << " games more than the computer did! You used " << a  << "     the most."; 
  }
}

上面的数组由

int humanrock = 0;
int humanpaper = 0;
int humanscissors = 0;
int highesthuman [3] = {humanrock, humanpaper, humanscissors};

运行我的整个程序时，出现错误消息一元的无效类型参数".我查了一下，但听不懂指针"或人们指的是什么.

When running my whole program I get an error saying "invalid type argument of unary". I looked this up but was not able to understand "pointers" or what people were referring too.

推荐答案

std :: max_element()接受两个迭代器作为参数，并返回一个迭代器.在您的情况下，迭代器是指针.因此，您应该更改

std::max_element() accepts two iterators as parameters, and returns an iterator. In your case iterators are pointers. So you should change

int a = max_element(highesthuman[0], highesthuman[2]); 

到

int a = *max_element(highesthuman, highesthuman + 3);
