In your class, many students are friends. Let’s assume that two students sharing a friend must be friends themselves; in other words, if students 0 and 1 are friends and students 1 and 2 are friends, then students 0 and 2 must be friends. Using this rule, we can partition the students into circles of friends. To do this, implement a function networks() that takes two input arguments. The first is the number n of students in the class. We assume students are identified using integers 0 through n-1. The second input argument is a list of tuple objects that define friends. For example, tuple (0, 2) defines students 0 and 2 as friends. Function networks() should print the partition of students into circles of friends as illustrated:

Avariable definition defines the name of a variable that will be used in a program, as well as

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).

Jason, samantha, ravi, sheila, and ankit are preparing for an upcoming marathon. each day of the week, they run a certain number of miles and write them into a notebook. at the end of the week, they would like to know the number of miles run each day, the total miles for the week, and average miles run each day. write a program to them analyze their data. your program must contain parallel arrays: an array to store the names of the runners and a two-dimensional array of five rows and seven columns to store the number of miles run by each runner each day. furthermore, your program must contain at least the following functions: a function to read and store the runners’ names and the numbers of miles run each day; a function to find the total miles run by each runner and the average number of miles run each day; and a function to output the results. (you may assume that the input data is stored in a file and each line of data is in the following form: runnername milesday1 milesday2 milesday3 milesday4 milesday5 milesday6 milesday7.)
