Objectives
Review C++ memory management, including copy constructors, destructors, and assignment operators.
Use Valgrind to check for memory leaks.
Review the procedures to access the GL servers and to compile programs on GL.
To ensure that you are able to submit project files on GL.
Introduction
In this project, you will complete a C++ class by writing a copy constructor, destructor, and assginment operator. Furthermore, you will write a test program and use Valgrind to check that your program is free of memory leaks. Finally, you will submit your project files on GL. If you have submitted programs on GL using shared directories (instead of the submit command), then the submission steps should be familiar.

Assignment

 
Step 1: Complete the Stack class
The Stack class implements a templated, linked list-based stack. Complete the class by writing the copy constructor, destructor, and assignment operator. The function prototypes are provided in stack.h. Since the class is templated, the implementation will be done entirely in stack.h; there is no stack.cpp file.

Step 2: Test your code
You must write a test program called mytest.cpp that checks correctness of the copy constructor and assignment operator. See driver.cpp for an example of how to use the stack class; output from the program is provided in driver.txt.

Following is a list of essential tests; we refer to the stack created by the copy constructor or on the left side of the assignment operator as the new stack; the stack from which the copy is made is the source:

Check that a copy is made. The new stack should contain exactly the same data as the source stack.
Check that the copy is deep. Modifying either stack (new or source) should not affect the other.
Check edge cases. For example, do they work correctly if the source stack is empty?
For the assignment operator, check that you have guarded against self-assignment.
Step 5: Check for memory leaks
Run your test programs using Valgrind. For example, assuming you have compiled mytest.cpp, producting the executable mytest.out, run the command

  valgrind mytest.out
If there are no memory leaks, the end of the output should be similar to the following:

  ==8613==
  ==8613== HEAP SUMMARY:
  ==8613==    in use at exit: 0 bytes in 0 blocks
  ==8613==  total heap usage: 14 allocs, 14 frees, 73,888 bytes allocated
  ==8613==
  ==8613== All heap blocks were freed — no leaks are possible
  ==8613==
  ==8613== For lists of detected and suppressed errors, rerun with: -s
  ==8613== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 0 from 0)
The important parts are in use at exit: 0 bytes and no leaks are possible. The last line is also important as memory errors can lead to leaks.

Step 7: Submit your files
See the What to Submit section, below.

Implementation Notes
Each project has a section on implementation notes. These point out some issues that you might encounter while developing your code. You should look through the Implementation Notes before you start coding.

The class declarations (Node and Stack) and provided function implementations in stack.h may not be modified in any way. No additional libraries may be used, but additional using statements are permitted.
The locations for the function implementations are clearly marked in stack.h. They must be written at the specified locations; in particular, they must not be written in-line.
Private helper functions may be used, but must be declared in the private section of the Stack class. There is comment indicating where private helper fuction declarations should be written.
You should read through the coding standards for this class.
What to Submit

You must submit the following files to the proj0 submit directory:

stack.h
mytest.cpp

Terrorist Hazard Reply

/in /by

You must write (2) replies of at least 140 words each to other classmates threads, and a minimum of 1 source is referenced appropriately for each reply. Note that both quantity and quality are important considerations when it comes to participation. For example, a message that says simply, I agree, does not constitute participation because it does not add anything of substance to the discussion.
In order to earn points, you must add something of substance to the discussion; this would consist of new ideas, your perspectives, pointed follow-up questions, etc.
Responding to a classmates post requires both the addition of new ideas and further analysis. A particular point made by the classmate must be addressed and built upon by your analysis in order to move the conversation forward. Thus, the response post is a rigorous assignment that requires you to build upon initial posts to develop deeper and more thorough discussion of the ideas introduced in the initial posts. As such, reply posts that merely affirm, restate or unprofessionally quarrel with the previous post(s) and fail to make a valuable, substantive contribution to the discussion will receive appropriate point deductions.

Reply to Anosha:

A hazard that has the potential to become the most dangerous is chemical warfare. Chemical weapons are created for the sole purpose of killing, injuring, or incapacitating people. They can enter the body through inhalation, ingestion, or the skin or eyes (Bullock, J. A., Haddow, G. D., & Coppola, D. P. (2016). If a chemical agent were to be released, this chemical agent could threaten human lives, livestock, insects, and birds. Chemical weapons can be administered through explosives, aerosol devices spreading chemicals in liquid, solid or gas form, and mixing food and water with the harmful chemical. Exposing chemical agents to the air threatens the lives of many and can be fatal. For example, the release of nerve agents can result in decreased heart rate and blood pressure and paralysis of the respiratory muscles and inhibition of the respiratory center. Ultimately, death results due to respiratory paralysis (Ganesan, K., Raza, S.K., & Vijayaraghaven, R.).

Although biological weapons are just as dangerous and devastating as chemical warfare, it is less of a threat to the United States. In terms of pure statistical risk, the likelihood of their use causing a major event is very low simply because it is so difficult and comparatively very expensive for small-scale terrorist elements to manufacture, store, and deploy them when considered in light of the wider range of attack options available (Bullock, J. A., Haddow, G. D., & Coppola, D. P. (2016).

Combining hazards such as chemical weapons and biological weapons could potentially be the biggest threat to the U.S if terrorists considered doing so. Although there are vaccinations that could cure the infected person and symptoms that could point out the sick, this could delay the seasoned expert due to the amount of information that one may or may not have on the combined hazards (Introduction to homeland security: principles of all-hazards risk management, p.98).

Principle 12 speaks of protecting each state from invasion and against domestic violence. An appropriate response to a chemical warfare attack against the U.S. is preparation and training. This includes protective gear and equipment, effective and humane ways of isolating those who may have been exposed to chemicals and continuing to perfect vaccinations.

Reply to Benjamin:

When considering CBRNE, natural, and technological hazards, I perceive technological hazards to be most dangerous to the United States in regards to a terrorist attack. Technological hazards, or man-made hazards as they are often called, are an inevitable product of technological innovation and human development. (Bullock, Haddow, Coppola, 2016) This means things like bridges, dams, and major infrastructures are all hazards included in this topic. If an attack was successful in taking down power and communication grids it would be detrimental to vital parts of life such as water, gas, and food supplies. The initial threat may be more mental than physical considering no power, no internet, no gas stations, and no cell phones would mentally cripple the affected area more so than physically with the exception of those dependent on electrically powered medical equipment and the ones who are unable to survive without heat or air due to age. This long term threat without intervention would lead to the physical threat by creating widespread panic and chaos since the effected people really would have no idea what happened other than everything shut down and didnt come back on. Depending on the size and type of the technological hazard or threat the response to this would, more times than not, be handled by the federal government. If it was a large bridge or large dam there would be an imminent death toll and immediate secondary structural issues elsewhere could occur as a result. If it was a large grid, power and/or communication, failure then an immediate notification to the people in the area to prevent widespread panic would be necessary first before repairs could be made.

Second I would place CBRNE, which stands for chemical, biological, radiological/nuclear or explosive, incidents can come in numerous forms such as a virus, nerve agent, or a nuclear device. While a nuclear incident of any type is a huge issue, terrorists typically dont have the ability to create or obtain the technology so this is the least likely hazard with the exception of an attack on a nuclear power facility. With the security well established and safety measures in place this event still is unlikely as well. Chemical or biological would be the main hazards of concern relative to their probability. If a biological event occurs it could take weeks to even realize since symptoms may not be immediately obvious. This would mean that the population effected could be large and the available treatment for the illness could be lacking in quantity. This could be an illness that effects only animals, humans, or plants or a combination such as humans and animals. A large scale persistent chemical attack would be detrimental as well. We use chemicals and transport them all over the country every day and it would be a target of opportunity to turn one of these hazards into a real time threat

Third comes natural hazards in regards to a terrorist attack. The ability to turn a natural hazard into a threat for terrorists is slim with the main exception of wildfires and mass movements. The hazards associated with these are very real for people in areas prone to wildfires and movements like avalanches and landslides. The wildfires that devastated Gatlinburg, TN in 2016 is a prime example of an unforeseen event that was not predicted and caused a large loss of property and revenue. Although this was not a terrorist threat this is something similar that could happen anywhere. An avalanche hazard that materializes could be devastating to mountain communities and impossible to stop as they happen so quickly.

A combined technological hazard and a CBNRE hazard would be the most dangerous in my opinion. Take out the infrastructure to respond and treat patients and then inflict the area with a biohazard would be a lethal combination. Regardless of the hazards and the threats they could materialize into Principle 24 – A free people will not survive unless they stay strong. is the key to survival for any citizen in any area that is effected by any event that has occurred or thwarted.
