Hi all
I am still working on Battleship for my class. I tell the user
to type in coordinates as expected in battleship, that is, a1 or
g4. I use a string to store that input, lowercase the string,
then convert it to a char array and cast the first element (the
letter) to an int, then subtract 97 since a actually means the
first gameboard slot (0, ascii a is 97 and 97?97=0). I take the
second element, the number, and cast to an int but subtract 49.
The problem is that my professor wants nothing less than a 15x15
grid. If I continue converting the way I am, then a1 and a12
look the same to the program since array[1]=1 and that is all it
looks for. How can I tell it that I want all elements after 0 to
be strung together to form an integer, but not added? Take b15.
I don't want to turn elements 1 and 2 into 6 but rather keep them
as 1 and 5 but string them together as 15. Maybe there is a way
to convert a string to an int? Thanks for any help.
Have a great day,
Alex
