Explanation: In the above program, the cin.get() function reads data through the keyboard
using first while loop. The if condition checks for blank space in the entered text. If space
is found, the putback() statement replaces space dot (.). The putback() sends the given
character in the input stream. The peek() also checks the ‘#’ symbol in the entered text, if it is
found, the ignore() statement ignores the character and the character will not be displayed on
the screen. The program is terminated when the key F6 or ctrl+z is pressed.
