solve B please

A. Write a C++ program to create a structure called "Time" that consists of three integer members: hours, minutes, and seconds. Ask the user to input a time value in the format of HH:MM:SS or in separate entries for each value (e.g. "Enter hours:". "Enter minutes:". "Enter seconds:"). The program should then store this time value in a variable of structure type and calculate the total number of seconds represented by the input time value using the formula: total secs = t1.hours 3600+t.minutes 60+t1. seconds. Once the calculation is complete, the program should output the resulting number of total seconds. B. Use the "time" structure from Q1. (A) which performs the following. 1. Request two-time values from the user, in the format of 12:59:59, and store them in struct type variables, 2. Convert each time value to seconds of type int. 3. Add the two converted values together. 4. Convert the result back to the format of hours-minutes-seconds. 5. Save the final result in a "time" structure variable. 6. Display the final result in the 12:59:59 format. 7. Create a function TimeDifference 0 that takes two structure variables as input parameters and returns their time difference as a structure
