Pointers is a difficult concept for many students.  I'm not sure how to make students understand the concept better. In an attempt to have you try to understand pointers, I'm going to ask you to write a paper that summarizes the chapter (or an online resource) that may help you understand the concept of pointers. Include the following topics in the paper. Include illustrations either from the book, or an online source or your own illustration.

• Come up with an introduction
• Pointer Variable Declarations and Initialization
• Pointer Operators
• Pass-by-Reference with Pointers
• Built-In Arrays
• Using const with Pointers
• sizeof Operator
• Pointer Expressions and Pointer Arithmetic
• Relationship Between Pointers and Built-In Arrays
• Pointer-Based String
• About Smart Pointers

You may include additional topics and illustrations to maybe help someone else understand the concept. Upload your final paper to this assignment page.

Part II.

Suppose there are students living in two dorms, called Gold and Blue. Students are each one of two types, Partiers and Studiers, which determines their preferences. Each dorm will vote on a tax rate, the proceeds of which will be used to fund a party. The mean of the votes will become the effective tax rate, and all residents of the dorm will be required to pay that fee. To simplify the problem, assume that all people may vote for either a tax of $0 or a tax of $100. (For example, if half of all people vote for $100 in a dorm, then the tax rate will be $50. The tax rate must be between $0 and $100.)

All students have a payoff (utility) equal to (1000−T)+μ(N ×T)

where T is the tax that they pay, and N is the number of people living in the dorm (so N × T is the total money spent on the party). The parameter μ is 0 for Studiers and 0.2 for Partiers.

Suppose that there are 100 Partiers and 100 Studiers. Initially, there are 70 Partiers and 30 Studiers in Gold Dorm, with the remainder in Blue. Given that allocation of people, what will be the tax rates in Gold and Blue? (2 points) (There will be two different tax rates.)

1. What is the total utility (payoff) in society (i.e., add up the payoff of all 200 students)?

2. Suppose now that people can move and sort. Suppose further that people choose where to go assuming that the tax rate and party size tomorrow is the same as it was yesterday. What will be the new tax rates in Gold and Blue after people sort?

3. What is the total utility (payoff) in society (i.e., add up the payoff of all 200 students)?

Approximately 22% of the daytime students at TCU are majoring in one of the four science colleges. If we were to take a random sample of 200 TCU students, what is the probability of getting a value for the sample proportion (p-hat) that is less than 0.20?

4]The GPAs of all students enrolled at a large university have an approximately normal distribution with a mean of 3.02 and a standard deviation of .29. Find the probability that the mean GPA of a random sample of 20 students selected from this university is 2.93 to 3.11
