C++ coding problem

please read uploaded file! 

Thank you


For this assignment, you will be creating classes with data

 

members and methods. The classes for each problem should be defined in a

 

separate .h file with the implementation of methods in a

 

separate .cpp file.

 

NOTE: Before submission, check to make sure your assignment

 

does not have any cout statements

 

For this assignment, you will create a new project within

 

CodeBlocks. You can name the project any name you like, but

 

each problem has a specific file name to be used for the .h and

 

.cpp files associated with the classes. See the individual

 

problems for those names. Your project will contain 5 files total:

 

main.cpp file, 2 .cpp files(one for each class), and 2 .h files(one

 

for each class). ? Once you have your code running on your virtual machine (VM), you

 

must submit it to the autograder by zipping only the .h and .cpp

 

files(not the main.cpp) for the created classes into a single file to be submitted. You must

 

also submit your code (.zip) to Moodle to get full credit for the

 

assignment. Your

 

upload

 

file

 

needs

 

to

 

be

 

named

 

Lastname_Firstname_Assignment7.zip for the grading script to

 

run.Your classes will be included and accessed in the testing

 

application?s main function.

 

If you do not get your assignment to run on COG before the assignment

 

deadline, you will have the option of scheduling an interview grade

 

with your TA to get a grade for the assignment. We?ll talk more about

 

scheduling the interview in lecture and recitation. Even if you do get

 

the assignment to run on COG, you can schedule the interview if you

 

just want to talk about the assignment and get feedback on your implementation. However, you must submit your code to

 

Moodle to get credit for your program.

 

Submitting Your Code to Moodle:

 

You must submit your code to Moodle to get full credit for the

 

assignment, even if the computer science autograder gives you

 

a perfect score.

 

Please also include comments in your code submission to

 

describe what your code is doing. Comments should also

 

include your name, recitation TA, and the assignment and

 

problem number. TAs will be checking that you code has comments and adequate indentation and variable names..

 

Problems:

 

These problems will require you to create a class description in a .h

 

file and place all the code for implementing the classes into a .cpp

 

file. You will need to write a main.cpp to hold your main() function

 

that will test your classes. You will #include ?yourfile.h? at the

 

beginning of your main.cpp to define your class for use in main()

 

function. REMEMBER: the code submitted to Moodle will be reviewed

 

and up to a 20 point reduction will be assessed for poor

 

coding style (lacking proper indentation, descriptive variable

 

names, or required comments) 1. Quarterback Ratings

 

In football, there is a statistic for quarterbacks called the

 

passer rating. There are five input parameters to the

 

calculation: pass completions, pass attempts, total passing

 

yards, touchdowns, and interceptions. The calculations

 

required have been listed below.

 

You will create a class where the class description is placed in

 

a file named

 

Quarterback.h and a file named Quarterback.cpp will

 

contain the implementation of the methods for that class.

 

COG will use these files to test your implementation of the

 

class. ? Create a class called Quarterback that has the following

 

private data members (all integer values except the string for

 

name): i.

 

i.

 

i.

 

i.

 

i.

 

i. i.

 

ii.

 

iii.

 

iv.

 

v.

 

vi. ? // Quarterback Name

 

Pass completions

 

Pass attempts

 

Total passing yards

 

Touchdowns

 

Interceptions class Quarterback

 

{

 

// data

 

members private:

 

? ? // methods

 

public:

 

Quarterback(); Quarterback(string data); ? // access methods

 

string getName();

 

void setName(string new_name);

 

int getComp();

 

void setComp(int value);

 

int getAtt();

 

void setAtt(int value);

 

int getYards();

 

void setYards(int value);

 

int getTD();

 

void setTD(int value);

 

int getPick();

 

void setPick(int value); ? // add the required functions here ?

 

private: // helper methods - only used by class methods float calcC(); float calcY(); float calcT(); float calcI(); }

 

The class should have two constructors, one that takes no

 

parameters, and one that takes a single string parameter that

 

contains the values for each of the members listed above (in

 

that same order) separated by a comma. Data Format Example:

 

D. McNabb, 180, 316, 2647, 18, 6

 

The class must have access methods for both getting and

 

setting the values of private members. There should also be a

 

method for each variable to increment the values, which could

 

be used in a simulated game. These methods do not return a

 

value, only update the object's data. PassCompleted(int yards) -- update comp, attempts,

 

yards.

 

PassAttempted() -- updates attempts. Touchdown(int yards) -- update comp, att, yards,

 

touchdowns.

 

Interception() -- updates attempts, interceptions

 

The class must have a method called PasserRating()

 

that performs the following calculations and returns a

 

float value:

 

C = (completions per attempt ? 0.30) * 5

 

Y = (yards per attempt ? 3) * 0.25

 

T = touchdowns per attempt * 20

 

I = 2.375 ? (Intercepts per attempt * 25)

 

If C, Y, T, or I is less than 0, then set it to 0

 

If C, Y, T, or I is greater than 2.375, then set it to

 

2.375

 

PasserRating = (C+Y+T+I)/6*100

 

The class must have a method called Evaluation() which will

 

return a subjective evaluation string based on the passer

 

rating. A rating is ?poor? if it is 85 or below, ?mediocre? if

 

above 85, ?good? if above 90, and ?great? if above 95.

 

To test your program, look up actual data on www.nfl.com

 

or http://www.pro-footballreference.com/years/2015/passing.htmor use the following

 

information from 2015: Philip Rivers, 437, 661, 4792,

 

29, 13

 

Drew Brees, 428, 627, 4870,

 

32, 11

 

Tom Brady, 402, 624, 4770,

 

36, 7 93.8

 

101.0

 

102.2 COG will test your code by using both the string

 

constructor and the default constructor in a simulated

 

game (calling the incremental functions, then asking for a

 

rating calculation). 2. Cycling: Power and Energy

 

This is a continuation of Assignment #3. See that

 

assignment for all the equations. If you had the correct

 

calculations in your solution for that assignment, you

 

should be able to reuse the code here. You will create a class where the class descriptions are

 

placed in a file named BikeRacer.h and a file named BikeRacer.cpp will contain the implementation of the

 

methods for those classes. COG will use these files to test

 

your implementation of the classes.

 

Create a class called Racer. The class Racer will contain

 

privatefloating point variables for data listed below. All

 

these data members should be private, with publicaccess

 

methods to get and set the values. Racer constructor will

 

need to initialize all the member variables. Mass of the bike in kg

 

Coefficient related to the resistance of the bike on the

 

road

 

Mass of the rider in kg

 

Velocity in m/s

 

Coefficient related to rider position(K)

 

Coefficient of drafting

 

//Access methods

 

Racer::setBikeMass(.

 

..)

 

Racer::getBikeMass() Racer::setBikeCR(...)

 

Racer::getBikeCR()

 

Racer::setRiderMass (...)

 

Racer::getRiderMass()

 

Racer::setCDraft(...)

 

Racer::getCDraft()

 

Racer::setK (...)

 

Racer::getK()

 

Racer::setVelocity (...)

 

Racer::getVelocity()

 

The power output for a cyclist (measured in Watts) can be

 

calculated from the power needed to overcome air resistance

 

and the power needed to overcome rolling resistance. Write a method Power() for

 

Racer to calculate the floating point value for power

 

required per second based on current racer and racer?s

 

bike settings.

 

Write a method to calculate the total power required to

 

travel a given distance in kilometers. TotalEnergy(float distance) will return the floating point value for total

 

energy as specified in the previous assignment?s write up.

 

Use the following values to test your classes:

 

Bike

 

M =15

 

Cr = 0.001

 

Racer

 

M = 63 k

 

= 0.18 v

 

= 10.8 CFdraft = 0.70

 

you should get 166.9 W
