Hello! I'm just having a little trouble! I've posted this question a few times and have learned a lot from each of them, but there is just still a few issues. I think the last answer was actually cut off on accident, but I still learned a lot.

When running the code and entering the game, it exits immediately after I make a selection for the coordinates. Also I need to hide the placement of the ships so they are not visible to the user. They are only supposed to appear once the user has sunk the whole ship. I've been implementing everyone's advice, but this assignment is just lost on me.

I appreciate any help!

For the most part this is what I am trying to do:

---populate a (10x10) board to sim a game of battleship

---There are 5 ships randomly placed on the board (this is determined randomly by computer and the user nor programmer will know the placements).

---Each ship will take a certain amount of hits to sink (refer to their lengths) and to enter a hit user needs to enter a row then col ( Ex: J9)

---after each attempt a message populates whether the gamer "hit" or "missed" the target and updates the board with an H or M accordingly.

----enforce preventative coding so if the gamer selects outside of the boards region, they are notified that their selection is invalid

---the user is given the option to start a new game or quit at the end

----use structs and dynamic memory allocation as necessary
