5.8 LAB: User-Defined Functions: Max magnitude CORAL LANGUAGE ONLY PLEASE Define a function named MaxMagnitude with two integer parameters that returns the largest magnitude value. Write a program that reads two integers from a user, calls function MaxMagnitude() with the inputs as arguments, and outputs the largest magnitude value. Ex: If the inputs are: 5 7 the function returns and the program output is: 7 Ex: If the inputs are: -8 -2 the function returns and the program output is: -8 Note: The function does not just return the largest value, which for -8 -2 would be -2. Though not necessary, you may use the absolute value built-in math function: AbsoluteValue
a c++ program for a (cafe system) that includes this specifications: -Functions (should include both: pass by value and pass by reference variables, void function and unction returning any value) - Array of structs (at least one single array of struct) - Selection and repetition structures as needed - Add your team members names as a comment in the first line of your program - You should print a menu to the user and offer him/her different services. - Main Services: 1-adding new item. 2-search for specific item. 3-update existing record. 4-delete. 5-Sort. 6-Display. 7-At the start, your program should populate the array(s) from a file and allow the user to edit it. At the end overwrite the same file with the latest contents of the array(s). 8-Provide another statistical report as separate text file e.g. the number of records, with date, time of last update. - The program should continue running until the user chooses to exit it. - Ensure to avoid any errors of any type (Run-time error,…
Function #2: largest Parameters: num1 - a floating point number being compared against num2 and num3 num2 - a floating point number being compared against num1 and num3 num3 - a floating point number being compared against num1 and num2 Description: Write a function that takes in three numbers as parameters and prints out the largest of the three. If two or all of the numbers are equal, or even all three, then just print the value once. Test Cases: >>>largest(433.1, 2340.32, 12323.7) 12323.7 >>>largest(12.0, 32.1, 32.1) 32.1 >>>largest(23.44, 23.44, 23.44) 23.44
This exercise assesses the skills required to develop user defined functions, and pointers. Task:Develop the program with Graphics properties to give a better look to your program. You need to explore the graphics libraries available in C++ e.g. <Graphic.h> *need to solve this Q with #include <iostream> Not other libary .* Exercise 2 Write a C++ program to develop a Vehicle Fine Management System for Police. The program will have the following features.1. A user defined function called “Student Registration”. This function prompts a user to enter a student’s personal data i.e., Student Number, Student Name, Age and City and stores them. 2. A user defined function called “Module Enrolment”. This function takes student number from themain function as an argument and prompts a user to enter student two modules details i.e. Module name, Module Code and Module Credits Hours (15 or 30) and stores them.

Write these codes in c language please. Thank you in advance 1. Define a function PrintFeetInchShort(), with int parameters numFeet and numInches, that prints using ' and " shorthand. End with a newline. Remember that "\n" in a string literal starts a new line. Ex: PrintFeetInchShort(5, 8) prints:5' 8" 2. Write a function so that the main() code below can be replaced by the simpler code that calls function MphAndMinutesToMiles(). Original main(): int main(void) { double milesPerHour; double minutesTraveled; double hoursTraveled; double milesTraveled; scanf("%lf", &milesPerHour); scanf("%lf", &minutesTraveled); hoursTraveled = minutesTraveled / 60.0; milesTraveled = hoursTraveled * milesPerHour; printf("Miles: %lf\n", milesTraveled); return 0; } 3. Define stubs for the functions called by the below main(). Each stub should print "FIXME: Finish FunctionName()" followed by a newline, and should return -1. Example output:FIXME: Finish GetUserNum() FIXME: Finish GetUserNum()…

done in c++ Program Specifications: Write a program that asks for a user's name and age, finds the ticket price based on the age, and prints out the user's name, age, and ticket price. The program must define the following 3 functions and call them in the main function. Create a function called getName that takes in no arguments and returns the name of the user. Create a function called getAge that takes in the argument age and uses pass-by-reference to set the age of the user. Ensure that the user cannot put in an age that is negative or greater than 100. Create a function called printTicket that takes in the user's name and age and does the following ○ If they are less than or equal to 13 years old set ticket_Price to 9.99. ○ If their age is greater than 13 and less than 65, set ticket_Price to 19.99. ○ If their age is greater than or equal to 65, set ticket_Price to 12.99. ○ Output to the console the user's name, age and ticket price.
Create a program using java data structures That has the user enter their pay rate; the program will require the employee to enter hours for two days ( they work two days a week); and the conversion must be done. via a recursive function (all calculation and display happen in a single function). Include an additional function to prompt the user for their numbers. Do NOT USE Stack ADT, ANY ADTs, or structures that we created in class. Employee - hoursWorked : int - payRate : double -Employee(void) Default constructor - has NO parameters and must NOT return anything. Sets both attributes to 0. -AddHours(hoursToAdd : int) : void Adds the given hours to add to the hoursWorked attribute. -SetPayRate(newPayRate : double) : void Changes the payrate attribute to the given new pay rate. -GetHoursWorked(void) : int {hoursWorked} Gives back the hoursWorked attribute -+ GetPayRate(void) : double {payRate} Gives back the payRate attribute. -GetGrossPay(void) : double {grossPay} Computes and…
