In this exercise, we use a typedefagain, and this time the code is quite straightforward.typedef char *string;int main(void){string a []b[]={"I", "like", "to", "fight,"},{"pinch,", "and", "bite."};printf("%s %s %s %s %s %s %s\n",a[0], a[1], a[2], a[3], b[0], b[1], b[2]);return 0;}Execute the program so that you understand its effects. If the typedef is replacedby the line#define string char *then the program will not compile. Explain why the typedef works, but the#define does not. To make the program work with the #define, a single characterneeds to be added. What is the character?

Answer is given below with explanation

Please help, the tasks on last paragraph. Laboratory work No. 5 "Fundamentals of the C ++ programming language: Arrays" One-dimensional arrays It often becomes necessary to store not one variable, but a set of variables of the same type. For example, a list of students in a class is a string-type dataset, the coordinates of a polygon's vertices, or the coefficients of a polynomial is a numeric dataset. Data structures are used to store datasets. The main data structure is an array. An array is a structure of the same type of data that occupies a contiguous area of memory. An array has size — the number of elements in it. Each element of an array has its own number (also called an index); an array element is accessed by specifying its index. In C ++, elements are numbered starting at 0, so the last element in an array is numbered 1 less than the size of the array. An array in C ++ is defined as follows: item_type id [size]; where_element_type is an arbitrary data type of the C ++…
Part III - Create Your Own Art Art.java In this part you will create a program Art.java that produces a recursive drawing of your own design. This part is meant to be fun, but here are some guidelines in case you're not so artistic. 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. Your program must be organized into at least three separate functions, including main(). All functions except main() must be private. For full credit, Art.java must not be something that could be easily rewritten to use loops in place of recursion, and some aspects of the recursive…
Objectives Java refresher (including file I/O) Use recursion Description For this project, you get to write a maze solver. A maze is a two dimensional array of chars. Walls are represented as '#'s and ' ' are empty squares. The maze entrance is always in the first row, second column (and will always be an empty square). There will be zero or more exits along the outside perimeter. To be considered an exit, it must be reachable from the entrance. The entrance is not an exit.Here are some example mazes:mazeA 7 9 # # ##### # # # # # # # ### # # # # ##### # # # ######### mazeB 7 12 # ########## # # # # # # # #### # # # # # # ##### ## # # # # ############ mazeC 3 5 # # # ## ## Requirements Write a MazeSolver class in Java. This program needs to prompt the user for a maze filename and then explore the maze. Display how many exits were found and the positions (not indices) of the valid exits. Your program can display the…

C Programming Language (Code With C Programming Language) Problem Title : Visible Trees There is a legend about a magical park with N × N trees. The trees are positioned in a square grid with N rows (numbered from 1 to N from north to south) and N columns (numbered from 1 to N from west to east). The height (in metres) of each tree is an integer between 1 and N × N, inclusive. Magically, the height of all trees is unique. Bunga is standing on the northmost point of the park and wants to count the number of visible trees for each Column. Similarly, Lestari is standing on the westmost point of the park and wants to count the number of visible trees for each Row. A tree X is visible if all other trees in front of the tree X are shorter than the tree X. For example, let N = 3 and the height (in metres) of the trees are as follows6 1 87 5 32 9 4 On the first column, Bunga can see two trees, as the tree on the third row is obstructed by the other trees. On the second column, Bunga can see…

def winning_card(cards, trump=None): Playing cards are again represented as tuples of (rank,suit) as in the cardproblems.pylecture example program. In trick taking games such as whist or bridge, four players each play one card from their hand to the trick, committing to their play in clockwise order starting from the player who plays first into the trick. The winner of the trick is determined by the following rules:1. If one or more cards of the trump suit have been played to the trick, the trick is won by the highest ranking trump card, regardless of the other cards played.2. If no trump cards have been played to the trick, the trick is won by the highest card of the suit of the first card played to the trick. Cards of any other suits, regardless of their rank, are powerless to win that trick.3. Ace is the highest card in each suit.Note that the order in which the cards are played to the trick greatly affects the outcome of that trick, since the first card played in the trick…
C++ Note: C-Strings char arrays should be now built as "string". This will help to simplify your work. 2. Create class methods (Setters and Getters) that load the data values. The Setter methods will validate the input data based on the criteria below and load the data into the class if valid. For strings, the data must be within the specified data size. (See #3 below) For zipCode, the number must be between 0 and 99999. City and State need to be converted and stored in uppercase. 3. Write a program that will create an instance of this class as an Object. Allow me to enter data for the Object and create and call a method that displays the data for the Object. During the input process, pass the input data to the setter method and confirm that the data entered is valid based on the class method return value. If not valid, prompt for me to re-enter the data until it does pass the class method's validation.(A do-while loop works well for this situation) I only…

8. Grade Book A teacher has five students who have taken four tests. The teacher uses the following grading scale to assign a letter grade to a student, based on the average of his or her four test scores: Test Score Letter Grade 90–100 A 80-89 B 70-79 C 60-69 D 0-59 Write a class that uses a String array or an ArrayList object to hold the five students' names, an array of five characters to hold the five students' letter grades, and five arrays of four doubles each to hold each student's set of test scores. The class should have methods that return a specific student's name, the average test score, and a letter grade based on the average. Demonstrate the class in a program that allows the user to enter each student's name and his or her four test scores. It should then display each student's average test score and letter grade. Input Validation: Do not accept test scores less than zero or greater than 100.
