7) [5 points) The following input buffer contains 20 keystrokes entered by the user from multiple prompts. The input buffer pointer is positioned at the first keystroke in column 0 (indicated by N). Read operations a-e are executed on the buffer in sequence. The pointer for any read operation starts where the previous read operation left it. After each read operation show what value will be stored in a variable, and where the pointer will be after the read. In the input buffer: blank represents the SPACE character R represents the ENTER character T represents the TAB character a-e represent non-whitespace characters. In the table below, for the value stored, use: B to represent the SPACE character N to represent nothing null R to represent the ENTER character T to represent the TAB character a-e to represent non-whitespace characters. Input buffer Read operation Value stored after read Buffer pointer after read input buffer pointer as start) a) cin b) cinget c) cin d) zetline e) gatline * Enter a number. 7) [5 points) The following input buffer contains 20 keystrokes entered by the user from multiple prompts.
