Which of the following statements a), b) or c) is false? O a. You interact with an object via a reference, which behind the scenes is that object's address (or location) in the computer's memory-sometimes called a “pointer" in other languages. O b. After the following assignment the variable x contains the value 7: X = 7 OC. After the assignment in part b), you might say that x "points to" (that is, "references") the object containing 7. O d.

- True or FalseReference variables can be used only to reference objects.Computer Science C# Programming Object Orientation Please use Arrays or ArrayLists where appropriate Implement a menu driven program that has some operations for a food truck. A food truck has multiple food items as well as a menu which contains a selection of the food items which will be sold for that day. A maximum of 10 food items can appear on the menu for any day. For each food item keep a code, description, category, price and quantity in stock (code, description and category are not usually changed). Create a comma delimited text file called "items.txt" for 15 or more food items, indicating the item's description, category, price and quantity in stock. Read all the food items from the text file “Items.txt” Display all the food items available for this food truck. Continuously prompt the user for a food item’s code to be placed on the menu until the menu is full or the user enters -1. Note that only food items which have a positive quantity in stock may be added to…True or false: When an object is passed to a function, but the function is not supposed to change it, it is best to pass it by value.
- Art.java In this part you will create a program Art.java that produces a recursive drawing of the design attached in the picture. Requirements Art.java must take one (1) integer command-line argument n that controls the depth of recursion. Your drawing must stay within the drawing window when n is between 1 and 7. (The autograder will not test values of n outside of this range.) You may not change the size of the drawing window (but you may change the scale). Do not add sound. Your drawing can be a geometric pattern, a random construction, or anything else that takes advantage of recursive functions. Optionally, you may use the Transform2D library you implemented in Part 1. You may also define additional geometric transforms in Art.java, such as sheer, reflect across the x- or y- axis, or rotate about an arbitrary point (as opposed to the origin). Your program must be organized into at least three separate functions, including main(). All functions except main() must be private. call…Static Variable: a variable whose lifetime is the lifetime of the program (static int x;) Dynamic Variable: It is a pointer to a variable (int *x;) Is this comparison true?Create a program in C language that calculates the month's day from a given year and year's day.

Anagrams may be several words long such as “CS AT WATERLOO” and “COOL AS WET ART”. Note that two phrases may be anagrams of each other even if each phrase has a different number of words (as in the previous example). Write a program to determine if two phrases are anagrams of each other. Input Specifications The input for the program will come from an input file in.dat, in.dat will have two lines of data, line (1) will have the first phrase and the line(2) will have the second phrase. You may assume that the input only contains upper case letters and spaces. Output Specifications The program will print out one of two statements: ”Is an anagram.” or, ”Is not an anagram.” All output will be to the screen.
