Reading txt file to char array

Question

im trying to read txt file to my char array[9][9]. I tried some tips from other topics, but they didn't work.

So, I have an example file.txt like this, which I saved myself, like this: it is 9x9

123------

---456---

------789

and so on, whitespaces here are ' ' instead of '-'. When I'm trying to read it, and put it to my array again, it is displayed like this:

123456789.

Here's my code:

system("cls");
ifstream sudoku_read;
string name_read;

cout << "Put a text name: "
getline(cin, name_read);
sudoku_read.open(name_read, ios::in | ios::binary);

for (int i = 0; i < 9;i++)
{
    for (int j = 0; j < 9; j++)
    {

        sudoku_read >> tab[j][i].number;

    }
}

I tried noskipws also but it does not work correctly.

Answer 1

char crs[100];
unsigned vindex = 0;
std::stringstream ss;
ss = sudoku_read.rdbuf();
std::string flstr = ss.str();
for(int i=0; i<strlen(flstr); i++){
    if(flstr[i] != ' '){
      crs[vindex++] = flstr[i];
    }
}
vindex = 0;
for (int i = 0; i < 9;i++)
{
    for (int j = 0; j < 9; j++)
    {
        tab[j][i].number = crs[vindex++] - '0'; //watch out it should be [i][j] by convention
    }
}

I have conventionally set crs' size to 100 since it is unspecified.

Assumptions:

• You have enough numbers in the file to fill in the matrix
• You condone using stringstream and cstring
