So my situation right now is, I need to read in(input from the user) up to 8 digits as characters (not numerical instead as a character input).
But only characters 0,1,2,3,4,5,6,7,8,9 is labelled as valid inputs. This means that the ASCII equivalent for these characters is between decimal 48-57
Anything below decimal 48 and above decimal 57 will deem the input as invalid.

The next step is to check how many inputs are there. Example if I were to enter "--------kaskldjklasd12345678" this will still only take as 8 inputs because it has 1,2,3,4,5,6,7,8 while the alphabets and symbols are being ignored. Basically, I want the program to identify if the user input is 8 characters(only between 0-9) or when the RETURN key is pressed, then I would want to store the characters into an array.

Right now, I'm figuring on how to store the input characters into an array. The program below is doing the comparing and addition for the counter to determine the counter=8. I'm stuck on how to store the values/character in an array.

The array storing should be only after the counter(d5) hits 8. So do I put ?



The code I have right now is:

I somehow managed to edit and make it work for the part I am asking, however I’m stuck at the second part.

I have managed to read the data from user input and compared it with ASCII Code and only accept a certain value which is between 48 - 57 which represents characters 0-9.

Now, I'm having a hard time figuring out how do I print a certain string based on the input of the user. The requirements is to enter a maximum of 8 digits(eg: 12345678) or when the RETURN character is captured(13 in ASCII) and the program will print a specific string based on the number typed in. Another example would be if a user inputs , this will still be treated as 8 digits as 1,2,3,4,5,6,7,8 is valid.

A specific string is being given to me as follows - this is part of the info that is given to me it continues to 9


The hard part is figuring how to retrieve the character I stored in the array and have it compare with a certain value so that if for example, the input is then the program knows it has to print
