AHPA #10:The Secure Array(use C programming)• A programmer that you work with, Peter, is a jerk.• He is responsible for an array [theArray] that is a key part of an importantprogram and he maintains a sum of the array values at location [0] in the array.• He won't give you access to this array; however, your boss has told you that youneed to get input from the user and then place it into the array.• Each evening Peter will scan the code and remove any illegal references to hisarray.• Using pointers, access Peter's array without him knowing it and place threevalues that you got from the user (101, 63, 21) at locations 3, 6, and 9.Recalculate the sum value and update it.

Mark the following statements as true or false. A double type is an example of a simple data type. (1) A one-dimensional array is an example of a structured data type. (1) The size of an array is determined at compile time. (1,6) Given the declaration: int list[10]; the statement: list[5] - list[3] * list[2]; updates the content of the fifth component of the array list. (2) If an array index goes out of bounds, the program always terminates in an error. (3) The only aggregate operations allowable on int arrays are the increment and decrement operations. (5) Arrays can be passed as parameters to a function either by value or by reference. (6) A function can return a value of type array. (6) In C++, some aggregate operations are allowed for strings. (11,12,13) The declaration: char name [16] = "John K. Miller"; declares name to be an array of 15 characters because the string "John K. Miller" has only 14 characters. (11) The declaration: char str = "Sunny Day"; declares str to be a string of an unspecified length. (11) As parameters, two-dimensional arrays are passed either by value or by reference. (15,16)
Question 4: (30 marks) A Math teacher is teaching Math course to a set of classes (each class may have different number of students) and want to check the behavior of his students in a homework report. The teacher gave the classes the same exam and marked their answer and wants to know the class whose students got the highest average. Help the teacher in the required analysis of student’s marks by implementing a Java program ClassAverageMArks2DimmArray using 2-dimensional array to store the students marks and then compute the average of each class student’s marks. The program has the following specification: • A Method titled averageClassMarks for computing the average (as double) of a class students marks (given to the method as a single-dimensional array) • Another Method titled averageAllClassesMarks for computing the average (as single array of double) of all the classes class student’s marks (given to the method as a 2dimensional array). This method has to repeatedly call the…
