It's important to note that the name of an array by itself is really a pointer to the first element of the array. Therefore passing an array to function is simple since you can just specify the name of the array. Are these statements true?
What transpires when a parameter for an array is sent in with either the ref or out keyword, and the results are observed?
1)Examine the above code that creates the array: a)How is the base type of the array specified? b)How is the length of the array specified? c)How many Strings are actually stored in the array after the array has been created? d)How is the base type of the ArrayList specified? e)How is the capacity of the ArrayList specified? f)What is the capacity of the ArrayList? g)What is the size of the ArrayList?
Revise the following Course class implementation in the following c++ code When adding a new student to the course, if the array capacity is exceeded, increase the array size by creating a new larger array and copying the contents of the current array to it. Implement the dropStudent function. Add a new function named clear() that removes all students from the course. Implement the destructor and copy constructor to perform a deep copy in the class. Write a test program that creates a course, adds three students, removes one, and displays the students in the course.
A pointer variable is just what it sounds like. What is its purpose? Exactly what does it mean to have a "dynamic array"? Pointers and dynamic arrays have what relationship?

Assume that the integer array myScores has been declared and assigned values. Assume that the integer variable size has been declared and initialized using the number of elements in the array myScores. Write a code block that declares a pointer to an integer and initializes it using the address of the array.
