Textbook Question

Chapter 5.7, Problem 3E

(Misc. application) a. Write a program to reverse the digits of a positive integer number. For example, if the number 8735 is entered, the number displayed should be 5378. (Hint: Use a do statement and continuously strip off and display the number’s units digit. If the variable numinitially contains the number entered, the units digit is obtained as (num % 10). After a units digit is displayed, dividing the number by 10 sets up the number for the next iteration.

Therefore, ( 8735 % 10 ) i s 5 a n d ( 8735 / 10 ) i s 873. The do statement should continue as long as the remaining number is not 0.)

b. Run the program written in Exercise 3a and verify the program by using appropriate test data.
