1. What power does creating your own variables give you that you wouldn’t otherwise have? 2. How does naming affect a variable’s creation and use?

3. What kinds of things are you able to set as a variable’s value?

4. How do the settings ‘For this sprite only’ and ‘For all sprites’ differ?

5. If you made one speed variable for all sprites, what would that mean?

Write a method in the heapintpriorityqueue class called merge that accepts another heapintpriorityqueue as a parameter and adds all elements from the other queue into the current queue, maintaining proper heap order such that the elements will still come out in ascending order when they are removed. your code should not modify the queue passed in as a parameter. (recall that objects of the same class can access each other's private fields.)

Consider the following statements: struct nametype{string first; string last; }; struct coursetype{string name; int callnum; int credits; char grade; }; struct studenttype{nametype name; double gpa; coursetype course; }; studenttype student; studenttype classlist[100]; coursetype course; nametype name; mark the following statements as valid or invalid. if a statement is invalid, explain why.a.) student.course.callnum = "csc230"; b.) cin > > student.name; c.) classlist[0] = name; d.) classlist[1].gpa = 3.45; e.) name = classlist[15].name; f.) student.name = name; g.) cout < < classlist[10] < < endl; h.) for (int j = 0; j < 100; j++)classlist[j].name = name; i.) classlist.course.credits = 3; j.) course = studenttype.course;

What is a point-in-time measurement of system performance?
