如何在 C++ 中比较字符串数组

Question

I am trying to compare two strings in my program so that I can arrange them in dictionary order. I am not allowed to declare an array like this: string arr[10] , instead I have to declare it like this: char arr[10][20] , where the [10] denotes the number of strings and the [20] denotes the size of each string.

To compare two strings I tried using something like: arr[5]>arr[7] , but it didn't work. Any ideas?

strcmp() should do the trick

Since you are limited to char arrays instead of string literals look at C documentation instead of C++ documentation. I assume you are a student as I had the same limitations.
