Hey guys could i get some help im getting an error saying "pass error before char"
but i cant see any syntax errors?

* If the user decides to "uncover square f1", the following can happen:
* - If a mine is accidentally uncovered, the game is lost.
* - If a numbered square is uncovered, this is marked in the "displayGrid"
* variable?,?,?,?,?,?,
?,?,?,?,?,?,
?,?,?,?,?,?,
?,?,?,?,?,?,
?,?,?,?,?,?,
?,?,?,?,?,?};
.
* - If a blank square is uncovered, this is marked in the "displayGrid"
* variable and all adjacent blank squares above, below, left, or right
* are also marked.
* In this example, square f1 is blank, so the "displayGrid" variable is
* updated to look like this:
* ---------------------------
* 1 2 3 4 5 6
* +---+---+---+---+---+---+ [ EXAMPLE 5]
* a | ? | ? | ? | ? | ? | ? |
* +---+---+---+---+---+---+
* b | 2 | 2 | 1 | ? | ? | ? |
* +---+---+---+---+---+---+
* c | | | 1 | ? | ? | ? |
* +---+---+---+---+---+---+
* d | | | 2 | ? | ? | ? |
* +---+---+---+---+---+---+
* e | | | 3 | ? | ? | ? |
* +---+---+---+---+---+---+
* f | | | 2 | ? | ? | ? |
* +---+---+---+---+---+---+
* ---------------------------
* From the above information, the user can already deduce where five of the
* six mines are located. They are in squares a1, a2, d4, e4, and f4. So, the
* user would next want to "flag square a1" and the other four squares.
* The user can only flag squares on unknown squares. So, our "displayGrid"
* variable now looks like this:
* ---------------------------
* 1 2 3 4 5 6
* +---+---+---+---+---+---+ [ EXAMPLE 6]
* a | F | F | ? | ? | ? | ? |
* +---+---+---+---+---+---+
* b | 2 | 2 | 1 | ? | ? | ? |
* +---+---+---+---+---+---+
* c | | | 1 | ? | ? | ? |
* +---+---+---+---+---+---+
* d | | | 2 | F | ? | ? |
* +---+---+---+---+---+---+
* e | | | 3 | F | ? | ? |
* +---+---+---+---+---+---+
* f | | | 2 | F | ? | ? |
* +---+---+---+---+---+---+
* ---------------------------
* The user can now deduce that there are no mines in squares a3, a4, b4, and
* c4. The user can now uncover these squares one at a time if he or she
* wishes. However, this is somewhat inefficient. Alternatively, the user may
* want to "sweep" around a numbered square that is considered safe because
* the adjacent mines have been (hopefully) correctly flagged.
* So the user can "sweep square b3". This effectively executes the "uncover"
* command on the surrounding 8 squares (but only the ones that are marked as
* UNKNOWN). After performing the "sweep square b3" command, the "displayGrid"
* variable looks like this:
* ---------------------------
* 1 2 3 4 5 6
* +---+---+---+---+---+---+ [ EXAMPLE 7]
* a | F | F | 1 | | | |
* +---+---+---+---+---+---+
* b | 2 | 2 | 1 | | | |
* +---+---+---+---+---+---+
* c | | | 1 | 1 | 1 | |
* +---+---+---+---+---+---+
* d | | | 2 | F | 2 | |
* +---+---+---+---+---+---+
* e | | | 3 | F | 4 | 1 |
* +---+---+---+---+---+---+
* f | | | 2 | F | ? | 1 |
* +---+---+---+---+---+---+
* ---------------------------
* The user can now flag the final mine at square f5. When all 6 mines are
* flagged, the user guesses are verified. If any guess is incorrect, then
* the user loses and the game is over. Otherwise the user wins the game and
* the game is over. The displayMinefield() function is called one last time
* with bad guesses marked as BAD_GUESS.
*
* This function is a large one, and it is recommended that you further
* modularise it. Leave this one until you have implemented the other six
* major functions. Additionally, you should implement the three commands in
* this order: flag, uncover, sweep.
