Answer to Question #173966 in C++ for jowel

Question

Write a class TimeStamp that represents a time of the day. It must have variables to store the number of seconds, minutes and hours passed. It also must have a function to print all the values. You will also need to overload a few operators.

Task 1: Create a list of objects of class TimeStamp. Task 2: Insert 5 time values in the format ssmmhh

i. 15 34 23

ii. 13 13 02

iii. 43 45 12

iv. 25 36 17

v. 52 02 20

Task 3: Delete the timestamp 25 36 17

Task 4: Print the list

Output should be: 15:34:23

13:13:02

43:45:12

52:02:20
