Question

Im trying to learn a bit about c++ and have run in to some trouble.

I have the following code:

char board[5][5];
ifstream myReadFile;
myReadFile.open("c:/test.txt");

for(int i=0; i<5; i++)    
{
    for(int j=0; j<5; j++) 
    {
        while (myReadFile.good())     
        {
            board[i][j] = myReadFile.get();                 
            cout << board[i][j];
        }
    }
}
myReadFile.close();

for(int x=0; x<5; x++)
{
    for(int y=0; y<5; y++)
    {
        
        cout << board[x][y];
    }
    cout << endl;
}

Now i was expecting the first loop to read the chars from the txt file and this works, so yeah!
But the second loop, i was expecting to print the same char back to cout. However this was not the case, so i add the line

cout << board[i][j]

to the first loop to see if they where loading correctly.
This is the result i get

Can someone explain why the second loop isn’t printing the same as the first.

Answer 1

you are replacing board[i][j] immediately after reading a char from file. Put the while loop as the outer most loop.

 while (myReadFile.good())     
        {
            board[i][j] = myReadFile.get();                 
            cout << board[i][j];
        }

Here, it continuously replaces board[i][j] with new character while i & j remains the same.
