Macro File: Create macros to print an int, print a char, print a string, get a string from the user, open file, close file, read file, and allocate heap memory. You can use more macros than these if you like. Main Program File: 1. Allocate 1024 bytes of dynamic memory and save the pointer to the area. 2. The main program is a loop in which you ask the user for a filename. If they enter nothing for the filename, exit the program. Otherwise: a. Open the file for reading. If the file does not exist, print an error message and terminate the program. b. Read the file into an input buffer space of 1024 bytes. c. Close the file. d. Output the original data to the console. e. Call the compression function. Save the size of the compressed data in memory.

The blank button automatically displays next to the data when you select a range of numeric data which is an available option for creating a chart

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).

1. ask the user how many questions are in the quiz. 2. ask the user to enter the key (that is, the correct answers). there should be one answer for each question in the quiz, and each answer should be an integer. e. g., 34 7 13 100 81 3 9 10 321 12 might be the key for a 10-question quiz. you will need to store the key in an array. 3. ask the user to enter the answers for the quiz to be graded. there needs to be one answer for each question. note that these answers do not need to be stored; each answer can simply be compared to the key as it is entered. 4. when the user has entered all of the answers to be graded, print the number correct and the percent correct. 5. add a loop so that the user can grade any number of quizzes with a single key. after the results have been printed for each quiz, ask "grade another quiz? (y/n)." note: you only have one array (the key). you are not creating a new key for each set of quiz answers.
