What´s the difference between string made by a struct

In the college I saw that my teacher made a program making a struct just like this:

#include <iostream>
using namespace std;

struct string_
{
  char _string [255];
}

struct person
{
   string_ birthday[5]; 
   string_ name[5];
}x;

I think that he did it because it seems to be easier to manipulate the strings in that way... The problem came when I did an exam just in that way and he said that it was unnecesary

How can I save the strings not doing that and not using the datatype "string". something like...?

#include <iostream>
using namespace std;

struct person
{
   char birthday[5][255]; 
   char name[5][255];
}x;

It may be because you cannot return array (char[255]) in a function, but you can return a struct, that contains an array.

For example

char[255] foo(); // cant do that
char* foo(); // can do that, but instead of copying string, only pointer to its begining is returned
string_ foo(); // can do that, and whole struct, that contains char[255] will be copied (returned)
