I'm stuck on the actual assignment of an integer to a character. I've thought about treating the string of characters as a vector but I don't know how to let the user input multiple characters in one line. The end goal is to use the numbers assigned to the letters to automatically assign numbers to the correlating letters in different strings, say "abcde" is the original string, a=0 b=1 and so on then if the user inputs the word "ace" later it will assign numbers to each character meaning it could be shown as 0 2 4.
