21.数组求最大值

#include<iostream>

using namespace std;

int main()

{

    int arr[] = { 300,350,200,400,250 };

    int max = arr[0];

    for (int i = 1; i < sizeof(arr) / sizeof(arr[0]); i++)

    {

        if (max < arr[i])//如果有值大于max

        {

            max = arr[i];//更新最大值

        }

    }

    cout << max << endl;

    system("pause");

    return 0;

}
