Using C++:

Write a program that will read up to ten letters into an array, named letter_box, and write the letters back to the screen in the reverse order. For example, if the input is abcd. (excluding the double quotes), then the output should be dcba (excluding the double quotes). Use a period as a sentinel value to mark the end of the input. Your program needs to handle the cases when the user enters more than 10 characters.
