In this activity, you will research various social networking sites and online and offline communities. Then write a concept document for a viable social network. It could be a personal network, a general-interest network, or a professional network. Your concept
document should answer the following questions:
• What concept is your site based on?
• What useful features will you incorporate in your site?
• Who are the target users that you have in mind?
• What type of content will you present on your site?
Finally, cite the sources that you used for your research

Assume the existence of a bankaccount class. define a derived class, savingsaccount that contains two instance variables: the first a double, named interestrate, and the second an integer named interesttype. the value of the interesttype variable can be 1 for simple interest and 2 for compound interest. there is also a constructor that accepts two parameters: a double that is used to initialize the interestrate variable, and a string that you may assume will contain either "simple", or "compound", and which should be used to initialize the interesttype variable appropriately. there should also be a pair of functions getinterestrate and getinteresttype that return the values of the corresponding data members (as double and int respectively).
