OOPs

In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.

Constructor

The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

A university course (not this one!) has three quizzes worth 20 points each and a final exam worth 40 points. A student's course score is simply the sum of points from the quiz and the final exam. A C structure type has been set up to hold a student's class record: struct mark_record { int id; // ID number int quiz[3]; // quiz scores, each out of 20 int final; // final exam score out of 40 }; Suppose that a number of these records are collected in an array, and a program needs to make a list of ID numbers of students with course totals greater than or equal to some level, for example 80 or 90. That leads to the following function interface: int ge_level(const struct mark_record *a, int n, int level, int *list); // REQUIRES: // n > 0. Elements a[0] ... a [n-1] contain meaningful mark records. // Elements list [0] ... list[n-1] exist. // PROMISES: // Return value (ru) is the count of course totals from a[0] ... a[n-1] that are >= level. list[o] ... list[ru-1] contain id numbers for // //…
