C++ how would you read this file into an array.
here is the pesudo file.

Code:
REREREEEEEERRRREER
SOMEStrinG1234 RERRRR  EEERRRREER
SOMEStrinG1224 REREREEEREERRR REE
SOMEStrinG1214 REREREREREREREEEER
SOMEStrinG1204 RERE EEEEEERRRRRRR
SOMEStrinG1294 REREEREEE ERRRREER
SOMEStrinG1284 REREREEEEEERR REER

here is my attempted code
Code:
#include <iostream>
#include <fstream>
#include <string>
#include <cmath>

#define SIZE 255
using namespace std;

int main(int argc, const char * argv[])
{


    ifstream inFile;
    inFile.open("inFile", ifstream::in);
    if (!inFile) {
        cerr << "Error: file could not be opened" << endl;
        return -1;
    }

    // reading file line by line // EOF = no chars;
    string line[SIZE];
    int i = 0;
    while (inFile.good()) {
        getline(inFile, line[i], '\n');
        cout << line[i] << " line// " << i << endl;
        i++;
    }
    cin.clear();
    
    char studentID[SIZE][SIZE];
    string grades[SIZE][SIZE];
    for (int i = 1, k = 0; line[i].length(); i++, k++) {
        cin >> studentID[k][SIZE] >> grades[k][SIZE];
    }

    cout << studentID[2] << endl << grades[2][1];
    
    ofstream outFile;
    outFile.open("outData.txt", ifstream::out);
    if (!outFile) {
        cerr << "Error: file could not be opened" << endl;
        return -2;
    }

    return 0;
}

The context is this is for an exercise out book I am attempting to solve.
the point I am at in my coding is i would like to test my results by adding this statement inline.

Code:
    cout << studentID[2] << endl << grades[2][1];

But it is not outputting anything to common out.
The section I am working in is about c++ arrays (non vector)
So that is the scope of solution(s) feedback I am looking for

Thanks in advance.

locale::codes::langext

Locale::Codes::LangExt(3pm)				 Perl Programmers Reference Guide			       Locale::Codes::LangExt(3pm)

NAME

       Locale::Codes::LangExt - standard codes for language extension identification

SYNOPSIS

	  use Locale::Codes::LangExt;

	  $lext = code2langext('acm');		       # $lext gets 'Mesopotamian Arabic'
	  $code = langext2code('Mesopotamian Arabic'); # $code gets 'acm'

	  @codes   = all_langext_codes();
	  @names   = all_langext_names();

DESCRIPTION

       The "Locale::Codes::LangExt" module provides access to standard codes used for identifying language extensions, such as those as defined in
       the IANA language registry.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default IANA language
       registry codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying language extensions. A code set may be specified using either a name, or
       a constant that is automatically exported by this module.

       For example, the two are equivalent:

	  $lext = code2langext('acm','alpha');
	  $lext = code2langext('acm',LOCALE_LANGEXT_ALPHA);

       The codesets currently supported are:

       alpha
	   This is the set of three-letter (lowercase) codes from the IANA language registry, such as 'acm' for Mesopotamian Arabic.

	   This is the default code set.

ROUTINES

       code2langext ( CODE [,CODESET] )
       langext2code ( NAME [,CODESET] )
       langext_code2code ( CODE ,CODESET ,CODESET2 )
       all_langext_codes ( [CODESET] )
       all_langext_names ( [CODESET] )
       Locale::Codes::LangExt::rename_langext  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangExt::add_langext  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangExt::delete_langext  ( CODE [,CODESET] )
       Locale::Codes::LangExt::add_langext_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangExt::delete_langext_alias  ( NAME )
       Locale::Codes::LangExt::rename_langext_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangExt::add_langext_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangExt::delete_langext_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
