Project 6: Prime Number output

Write a void function that uses two nested for loops and the modulus(%) operator to detect and print to a specified output file, the first n prime integers. Recall that a prime number is a number that is evenly divisible only by 1 and itself.
Hint: the function prototype is : void primeGen(int n, ofstream& file);
and a precondition is that file is defined.

Project 5: Surture Packaging

Page 221, Problem 24

Due: next Monday midnight, 3/4/13


Suture Packaging. Sutures are strands or fibers used to sew living tissue together after an
injury or an operation. Packages of sutures must be sealed carefully before they are shipped to
hospitals so that contaminants cannot enter the packages. The object that seals the package is
referred to as a sealing die. Generally, the sealing die is maintained at an established temperature
and must contact the package with a predetermined pressure for an established time period. The
time period in which the sealing die contacts the package is called the dwell time. Assume that
the acceptable range of parameters for an acceptable seal, are the following:

Temperature: 150-170 degree C
Pressure: 60-70 psi
Dwell time: 2-2.5 s

24. A data file named suture.dat contains information on batches of suturtes
that have been rejected during a one-week period. Each line in the data file contains the batch
number, the temperature, the pressure, and the dwell time for a rejected batch. The quality
control engineer would like to analyze the information and needs a report that computes the
percent of the batches rejected due to pressure, due to temperature and the percent rejected due to dwell time. It is
possible that a specific batch may have been rejected for more than a reason and should be
counted in all acceptable totals. Write a program to compute and print these three percentages.
Use the following test data:
(The red numbers are what actually in your file.
-99s are sentinel signal for end checking.
You may want to use my class example(in dropbox) as your template)

(In order to make sure your program works properly, you could manually check out the results,
since the data file is very small.
For example, due to Temperature, it fails at batch 24551. So the percentage would be 1/5 = 20%
You could also check others)

Batch Number   Temperature   Pressure     Dwell Time

24551                145.5                62.3                2.23
24582                153.7                62.3                2.52
26553                160.3                62.3                2.51
26623                159.5                62.3                2.01
26642                160.3                62.3                1.98
-99                     -99                   -99                     -99

Problem 14:

int a = 750;

if( a > 0 )

if(a >= 1000)

a=0;

else

a*=2;

else

a*=10;

Project 3: Age problem

Create an program that allows the user to input an age in years and then displays one of the following (or similar) responses. You program should be able to figure out how many years to display in some of the responses :

Age Range		Response
0 < age <6		You are considered a young minor. But, in approximately ___ year(s) you will be able to attend school!
6<= age<16		In approximately ___ year(s) you will be able to drive!
16<=age<21		In approximately ___ year(s) you will be of legal drinking age.
21<=age<35		You are of legal drinking age. In approximately ___ year(s) you will be able to run for president!
35<=age<120		You are old enough to run for U.S. President.
age >= 120		You are too enough to run for U.S. President.

Tip: the most suitable type of age is "int"

       "if-elseif-else" would be perfect for this program

Project 2: Degree Conversion Assignment

Textbook page 91, problem 26

Here are some instructions.

1. You don't have to define any class in this project. We just need basic arithmetic programming.
2. You could use hard-coded degrees in your program. In other words, you don't have to ask user to input anything with "cin". ( However, if you could, it would be better but no extra credit.)
3. You do have to use "cout" to show your results on the screen.
4. Take care of the "integer division" issue.

Due time would next Wednesday 2/6/13 midnight.

Project1: Hello World

Hello world on your machine.

Upload both the cpp file and executable.

Windows:

Follow the instruction I uploaded to install the MinGW.

Linux:

In your terminal, type

sudo apt-get install build-essential

MacOS:

Install Xcode where you could download from 

https://developer.apple.com/downloads/index.action

Fill in the survey forms to get access to developer zone.

Then search the corresponding version based on your system.

Mountain Lion or Lion  Xcode 4.5.2

Snow leopard  Xcode 3.2.2 developer tools

Leopard  Xcode 2.5

Then in the terminal, do what I did on class.
