C ++数组中的Max [英] Max In a C++ Array

问题描述

我正在尝试通过使用算法库/标头中的max函数在用户制作的数组中找到最大"元素.

I am trying to find the 'biggest' element in a user made array ,by using the max function from the algorithm library/header.

我已经在cplusplus参考站点上进行了一些研究，但是我只看到了如何使用max函数比较两个元素.相反，我试图使用函数"max"显示最大数量，而不必进行"for"循环来找到它.

I have done some research on the cplusplus reference site but there I only saw how to compare two elements using the max function. Instead I am trying to display the maximum number using a function 'max' ,without having to make a 'for' loop to find it.

例如:

数组:array[]={0,1,2,3,5000,5,6,7,8,9} 最高值:5000

我编写了这段代码，但是它给了我很多错误，这可能是问题所在?

I have made this code but it gives me a bunch of errors, which can be the issue?

#include <iostream>
#include <algorithm>
using namespace std;
int main()
{
    int array[11];
    int n = 10;
    for (int i = 0; i < n; i++) {
       array[i] = i;
    }
    array[5] = 5000;
    max(array , array + n);
    for (int i = 0; i < n; i++)
        cout << array[i] << " ";
    return 0;
}

推荐答案

max_element是您需要的功能.它将迭代器返回给定范围内的max元素.您可以像这样使用它:

max_element is the function you need. It returns an iterator to the max element in given range. You can use it like this:

cout << " max element is: " << *max_element(array , array + n) << endl;
