I have manipulated the DND code from Lab 4 to be able to be read by C++ (attached to this homework). Now, modify the code such that instead of storing the characters and traits in arrays, create a character object to store the traits. Store each characteristic (wisdom, dexterity, etc.) as attributes in the character object. Assume that the traits will always be in this order: Strength, Dexterity, Constitution, Intelligence, Wisdom, and Charisma. HINT: Be sure that you are creating the objects with the following attributes: name, strength, dexterity, constitution, intelligence, wisdom, and charisma. Do not worry about creating these attributes dynamically. Once you have read in all of the data and created the objects, store the characters in a vector. Use a loop to print out the character information from the character vector. Will's strength is: 11 Will's strength is: 11 Will's dexterity is: 12 Will's constitution is: 4 Will's intelligence is: 17 Will's wisdom is: 2 Will's charisma is: 13 Mike's strength is: 2 Mike's dexterity is: 20 Mike's constitution is: 18 Mike's intelligence is: 16 Mike's wisdom is: 7 Mike's charisma is: 2 Dustin's strength is: 2 Dustin's dexterity is: 5 Dustin's constitution is: 3 Dustin's intelligence is: 7 Dustin's wisdom is: 18
Use inheritance to create the following tree: Food Meat Chicken Beef Vegetable Spinach Tomato Fruit Strawberry Apple Then, in main, create a function that will take in a type of food and return the inheritance chain. Please enter the type of food: Strawberry Strawberry is a type of Fruit which is Food Please enter the type of food: Chicken Chicken is a type of Meat which is Food HINT: The code that created the last line looks like this: cout ≪ c.type ≪ " is a type of " ≪ c.group ≪ " which is " ≪ c. name;
You can use malloc, calloc, and realloc in C++ the same way that you can in C−so be sure to watch the memory allocation lecture. You can apply everything that you learned from C in C++. Recall that realloc is called with (int *)realloc (p,x) where p is a pointer that has previously been declared and x is the size that the user wants to reallocate. We want to show how we can use realloc to approximate the maximum size of an array that you can create in C++. First, use malloc to create space for an array in C++. Then, create a loop that will use realloc to increase the size of that array by a predetermined amount (I chose an increase of 1000000− feel free to use your own sizes if you wish). If you create a pointer ptr (which should be returned by realloc), you can print the location of the ptr in memory with cout ≪ ptr ≪ endl. To end the loop, check to see if the pointer returned by realloc is the null pointer. This will be a sign that you have reached your maximum memory size. Print the size of the array along with where the array is being stored (your output will differ):
