在C语言中,没有内置的is_sorted函数。但你可以使用标准库提供的sort函数来对数组进行排序,然后通过手动编写代码来判断数组是否已排序。以下是一个示例代码:
```c
#include <stdio.h>
int is_sorted(int arr[], int size) {
for (int i = 0; i < size - 1; i++) {
if (arr[i > arr[i + 1]) {
return 0; // 数组未排序
}
}
return 1; // 数组已排序
}
int main() {
int arr[] = {1, 2, 3, 4, 5};
int size = sizeof(arr) / sizeof(arr<span class="em">1</span><span class="em">2</span><span class="em">3</span>
