force two digits on an array for a 15 puzzle game-CodePudding

I am making a 15 puzzle game for school but right now it only has 9 numbers but if i add 2 digit numbers it messes up the whole grid. So I want there to be 2 digits on all numbers (2→→02).

int[,] tab = { { 2, 1, 7 }, { 6, 9, 4 }, { 3, 0, 7 } };

Since you are working with an 2D array you can do something like this:

int[,] tab  = { { 2, 1, 7 }, {  6, 9, 4 }, {  3, 0, 7 } };

for (int i = 0; i < 3; i  ) {
   for (int j = 0; j < 3; j  ) {
      Console.Write(String.Format("{0,2:00} ", tab[i,j]));
   }
   Console.Write("\n");
}

Here we are using String.Format to print the numbers as two digits. Since there is only one digit for the integers in the table, a leading zero will automatically be added. So for your code the output would be:

02 01 07
06 09 04
03 00 07

When displaying the numbers, format the strings. Here's an example:

int value = 2;
string result = String.Format("{0,2:00}", value);
Console.WriteLine(result);

The example displays the following output:
02
