sort()升序排列

sort()函数可以用于对数组进行升序排列。它有三个参数，第一个参数是数组的首地址，第二个参数是排序的元素个数。默认情况下，sort()函数按照升序排列。你可以直接使用sort()函数来对数组进行升序排列，无需自己写排序函数。以下是一个示例代码：

#include <iostream>
#include <algorithm>
using namespace std;

int main() {
    int arr[] = {4, 2, 7, 1, 5};
    int n = sizeof(arr) / sizeof(arr << " ";
    }

    return 0;
}

运行以上代码将输出：1 2 4 5 7，即数组元素按升序排列。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
