(a) Outline any four features of Object-Oriented Programming OOP, giving examples in each case. (b) Consider the following code fragments: If a = 10; Evaluate the new value of “b” in the following: (i) b = ++ a; (ii) b = a ++; What value would a and b store in (i) and (ii) after program execution?

Programming OOP, giving examples in each case.
(b) Consider the following code fragments: If a = 10; Evaluate the new value of “b” in the following:
(i) b = ++ a;
(ii) b = a ++;
What value would a and b store in (i) and (ii) after program execution?
2. Create a C++ program that makes use of three arrays; name, mark, grade. The program should accept the names and marks of a number of students to be entered by the user. Use the number of students as the size of the arrays.
Grades are computed and stored in the grade array using the criteria:
100 – 60 = A;
59 – 40 = B;
below 40 = C.
The program should continuously request a user who enters a mark below 0 or above 100 to enter a mark in the range 0 – 100. Finally, the program should display the list of students in this format: Name | Mark | Grade
Q3. Create a structure called time. Its three members, all type int, should be called hours, minutes, and seconds. Write a program that prompts the user to enter a time value in hours, minutes, and
seconds. This can be in 12:59:59 format, or each number can be entered at a separate prompt
(“Enter hours:”, and so forth).
The program should then store the time in a variable of type struct time, and finally print out the total number of seconds represented by this time value:
long totalsecs = t1.hours*3600 + t1.minutes*60 + t1.seconds
