Design a program that asks the user to enter a string

The string will then be displayed back to the user

This is followed by determining the number of

alphabetic characters

numeric characters

lower$\_$case letters

upper$\_$case letters

whitespace characters

and then displaying them

The user should be given additional chances to enter additional strings

and each time a string is entered, the above process is to be performed

The inputting is to stop, when the user enters "end" as the input string

At that point, total number of

alphabetic characters

numeric characters

lower$\_$case letters

upper$\_$case letters

whitespace characters

are to be displayed and the program terminated

An algorithm:

Prompt the user to enter a string at the keyboard

As long as the string is not "end"

Display the string, along with an appropriate message

Examine the current character of the string

If it's alphabetic, update the alphabetic$\_$counter and the total$\_$alphabetic$\_$counter

If it's numeric, update the numeric $\_$counter and the total$\_$numeric$\_$counter

If it's a lower$\_$case letter, update the lower$\_$case $\_$counter and the total$\_$lower$\_$case$\_$counter

If it's a upper$\_$case letter, update the upper$\_$case $\_$counter and the total$\_$upper$\_$case$\_$counter

If it's a whitespace character, update the whitespace $\_$counter and the total$\_$whitespace$\_$counter

Continue from step $2\mathrm{.}2$ with the next character until done with this string

Display the alphabetic$\_$counter, numeric $\_$counter, lower$\_$case $\_$counter, upper$\_$case $\_$counter, and whitespace $\_$counter, each on a separate line, and each along with an appropriate message

Prompt the user to enter another string at the keyboard

Display the total$\_$alphabetic$\_$counter, total$\_$ numeric $\_$counter, total$\_$lower$\_$case $\_$counter, total$\_$ upper$\_$case $\_$counter, and total$\_$ whitespace $\_$counter, each on a separate line, and each along with an appropriate message

Stop
