Assignment; For this component, you will write a report or critique on the paper you chose from Assignment 1. Your report should be limited to approx. 1500 words (not including references).

Use 1.5 spacing with a 12 point Times New Roman font. Though your paper will largely be based on the chosen article, you should use other sources to support your discussion or the chosen papers premises.

Citation of sources is mandatory and must be in the IEEE style.

TOPIC: Social Engineering and phishing attacks

Your report or critique must include: Introduction: Identification of the paper you are critiquing/ reviewing, a statement of the purpose for your report and a brief outline of how you will discuss the selected article (one or two paragraphs).

Body of Report: Describe the intention and content of the article. If it is a research report, discuss the research method (survey, case study, observation, experiment, or other method) and findings. Comment on problems or issues highlighted by the authors. Report on results discussed and discuss the conclusions of the article and how they are relevant to the topics of this Unit of Study.

3 Conclusion: A summary of the points you have made in the body of the paper. The conclusion should not introduce any ‘new’ material that was not discussed in the body of the paper.

I created a shoppingcart program but I'm getting a few compilation failed errors:

1) Tests that ItemToPurchase("Bottled Water", "Deer Park, 12 oz.", 1, 10) correctly initializes item compilation failed

2) Tests default constructor and accessors for ShoppingCart Compilation failed

3)Tests ShoppingCart("John Doe", "February 1, 2016") correctly initializes cart Compilation failed

4) Tests that getNumItemsInCart() returns 6 (ShoppingCart) compilation failed

5) Test that getCostOfCart() returns 9 (ShoppingCart) compilation failed
