Extracted text: Q2: Write a program which stores time information in a structure. The time structure should store the data in hours:minutes:seconds format (12:59:59). You must validate the input e.g if user enters valid data for each of the member of the structure. Create 3 objects of time structure and ask user to enter value for each member of each object. Finally, retrieve the data from each object and display the total number of seconds of the entered time. Note: time is in 12 hours format and not in 24 hours format.
