- In Pseudocode #7 – List 4 main data types we used in this course and describe the data that is stored in each one. List examples of variable names that make sense for each data type. #8 – Debug this input validation function and fix it. There is a lot wrong with it! Function Integer getNumberGreaterThanX(msg, x) myInteger = getInteger(msg) While myInteger < x Display "The number must be < “, myInteger , “. Try again." Input x End While End Function Write the corrected function below: #9 – Write a validation function based on the provided variables and call statement below. The validation function should return an Integer value greater than zero or print an error message until an acceptable value is entered. Declare Integer positiveValue = 0 Declare String message = "Enter the year you were born (no negative numbers!)" positiveValue = getNumberGreaterThanZero(message) Write the function definition below:arrow_forwardComputer Science csv file "/dsa/data/all_datasets/texas.csv" Task 6: Write a function "county_locator" that allows a user to enter in a name of a spatial data frame and a county name and have a map generated that shows the location of that county with respect to other counties (by using different colors and/or symbols). Hint: function(); $county ==; plot(); add=TRUE.arrow_forward5. Memory Layout Given the C struct definition below struct Simplestruct { int i; char c; double d; unsigned char a[11]; float f; }; struct Simplestruct ssp; Assume that int's are 4 bytes and have 4 byte alignment and that double has 8 byte alignment and float has 4 byte alignment. if calling printf("$x\n",ssp) yields CA028, what is the address of each field? You should express the answers in hexadecimal. &ssp->i = &ssp->c = &ssp->d = &ssp->a = &ssp->f =arrow_forward
- 1) Define a global variable Emps that is an array of pointers to employee structs. 2) Change your createEmployee function to add the new employee to the Emps array. It should place it in the first slot that contains a NULL. 3) Write a listEmployees function that will call your display function on each employee in the array. 4) Change main to have a loop that looks for user commands. • If the user types HIRE, you should call createEmployee. If the user types LIST, you should call listEmployees. • If the user types QUIT, you should exit the loop, which will then cause the program to exit. 5) Write a findEmployee function that takes a string parameter and returns the employee pointer with that name or NULL if no such person exists. Change main to add a FIND name command that will find and display a single employee.arrow_forwardStructural Verification Structural verification is, in this case, validating that a data structure is formed according to its specification. For this lab you are given an essentially arbitrary specification, but you could think of this being used to verify a data structure produced by a program that must have certain properties in order to be used correctly. For example, a list must not be circular, or an image file might require a particular header describing its contents. You must implement this function, which examines a matrix and ensures that it adheres to the following specification: bool verify_matrix(int x, int y, int **matrix); This function accepts an X dimension, a Y dimension, and a matrix of y rows and x columns; although it is declared as int **, this is the same type of matrix as returned by parse_life() in PA1, and you should access it as a two-dimensional array. Note that it is stored in Y-major orientation; that is, matrix ranges from matrix[0][0] to matrix[y 1][x -…arrow_forwardGame of Hunt in C++ language Create the 'Game of Hunt'. The computer ‘hides’ the treasure at a random location in a 10x10 matrix. The user guesses the location by entering a row and column values. The game ends when the user locates the treasure or the treasure value is less than or equal to zero. Guesses in the wrong location will provide clues such as a compass direction or number of squares horizontally or vertically to the treasure. Using the random number generator, display one of the following in the board where the player made their guess: U# Treasure is up ‘#’ on the vertical axis (where # represents an integer number). D# Treasure is down ‘#’ on the vertical axis (where # represents an integer number) || Treasure is in this row, not up or down from the guess location. -> Treasure is to the right. <- Treasure is to the left. -- Treasure is in the same column, not left or right. +$ Adds $50 to treasure and no $50 turn loss. -$ Subtracts…arrow_forward
