C++ console program. The current code is working with exception to one item. When testing, if an 'upper case' capital alpha character is used, it errors out because the  'upper case' letter is not found in the array matrix. I am looking for a solution that does not included adding the entire alphabet, in uppercase, to the matrix. Please do not change my existing code, with exception to the edits or changes to fix the issue. Please provide the edited source code as a solution or answer to this question. The following are test sequences to use for testing: 

1)  {#&@ = nice

2)  [@@, !, (#<@ ][ = meet at five pm

3) Y$% -!<@ ${&@ !)!#{ ($#+@* [/ ]+!{: = You have once again foiled my plans

In test #3, please note that the 'Y' will cause an error during testing because the upper case letter is not recognized in the array matrix. The solution for this is what I am looking for, with out changing the rest of my existing code. #1 and #2 works properly.
