Strings / char arrays inside a structure

I am trying to create a structure containing several arrays of strings inside it. For my purposes, I wanted to use std :: string arrays, but char * arrays would also work if they could do the job. In any case, I cannot figure out how to initialize things. This is what I have:

initialize.h

#include <string>

struct myStruct
{
    std::string x[22];
    std::string y[8];
};

extern myStruct data[22];

myform.cpp

#include <initialize.h>
#include <string>

myStruct data[22];

data[0].x = {"a", "b", "c", "d", ...};

I get errors that look like this:

Error 1 error C2059: syntax error: '{' Error 2 error C2143: syntax error: missing ';' before '{' Error 3 error C2143: syntax error: missing ';' before '}'

I tried various permutations with char * or std :: string * arrays, but to no avail, I was pretty stuck. Did I forget something fundamental?

Thanks in advance.

Other comments are true, but I believe there is one more thing you can do. You can initialize the structure when you declare it in your header:

struct myStr
{
  string x[22];
  string y[8];
} data[22] = { {...}, {...}, ... };

It will be long and ugly too, but can solve your question. As others have said, you cannot violate this and assign it after creating the instance.
