Please do the following and show execution code and output! Write two Haskell functions to calculate ticket prices. Tickets for those ages 12 and under are $8.50, tickets for those between 13 and 65 are $14.50 and those older than 65 are $9.00. The second function should calculate tax – assume tax is 12%. Using function chaining to calculate the total cost. The main function should ask what type of ticket the person wants (child, adult, or senior) and call the functions that you wrote. Show the type signatures of the functions you write.
Mark the following statements as true or false: a. To use a predefined function in a program, you need to know only the name of the function and how to use it. (1) b. A value-returning function returns only one value. (2, 3) c. Parameters allow you to use different values each time the function is called. (2, 7, 9) d. When a return statement executes in a user-defined function, the function immediately exits. (3, 4) e. A value-returning function returns only integer values. (4) f. A variable name cannot be passed to a value parameter. (3, 6) g. If a C++ function does not use parameters, parentheses around the empty parameter list are still required. (2, 3, 6) h. In C + + , the names of the corresponding formal and actual parameters must be the same. (3, 4, 6) i. A function that changes the value of a reference parameter also changes the value of the actual parameter. (7) j. Whenever the value of a reference parameter changes, the value of the actual parameter changes. (7) k. In C++, function definitions can be nested; that is, the definition of one function can be enclosed in the body of another function. (9) l. Using global variables in a program is a better programming style than using local variables, because extra variables can be avoided. (10) m. In a program, global constants are as dangerous as global variables. (10) n. The memory for a static variable remains allocated between function calls. (11)
1) Write an iterative function that takes two int type variables named (h) and (k) as the input parameter and calculates the h ** k value and returns the answer. 2) In the main function, take two integers of int type (g) and (b) from the screen. Using the function you created in (1), calculate the value of and print the result on the screen.

Code using c++ 3. From Person to People by CodeChum Admin Now that we have created a Person, it's time to create more Person and this tech universe shall be filled with people! Instructions: In the code editor, you are provided with the definition of a struct Person. This struct needs an integer value for its age and character value for its gender. Furthermore, you are provided with a displayPerson() function which accepts a struct Person as its parameter. In the main() function, there's a pre-created array of 5 Persons. Your task is to ask the user for the values of the age and gender of these Persons. Then, once you've set their ages and genders, call the displayPerson() function and pass them one by one. Input 1. A series of ages and genders of the 5 Persons Output Person·#1 Enter·Person's·age:·24 Enter·Person's·gender:·M Person·#2 Enter·Person's·age:·21 Enter·Person's·gender:·F Person·#3 Enter·Person's·age:·22 Enter·Person's·gender:·F Person·#4…
C++ programming question: Suppose we have just discovered an alien planet (we will call it Mars), and on this planet one year is divided into 15 months and each month consists of 30 days. i. Write the code for a struct charontime to hold years, months, and days for time on Charon -all ints. ii. Write a function that takes an int parameter that represents the number of Charon days, converts it to years, months, and days on Charon and returns this information in a struct charontime. So for example it will convert 800 days into a struct that represents 1 year, 11 months, and 20 days. iii. Write a function that takes a struct charontime parameter and returns the total number of Charon days represented by the struct. iv. Write a function that takes a filename and an array of struct charontime, opens the file, reads each line as the number of Charon days, converts this to a struct charontime and stores this in the array.

Please help me explain the following void function c++ code, which I did not understand. Especially for the first void function and int main(), I do not understand why the first void function enter the number and the int main function print out the final answer. #include <iostream>using namespace std; void getNumber(int *input); void doubleValue(int *val); int main(){ int number; getNumber(&number); doubleValue(&number); cout<<"That value doubled is"<<number<<endl; return 0;}void getNumber(int *input){ cout<<"Enter an integer number:"; cin>>*input; }void doubleValue(int *val){ *val *=2;}
In C++ Please Modify the program 8-31 from page 584, 585 by adding the following: 1. Add a prototype before main() like: void bubbleSort(Circle [], int); 2. On line 21 add the following function call: bubbleSort(circle, SIZE); 3. After main() function add the definition for bublleSort() function similar to the one on page 628. Evidently you must change the Inventory data type with Circle. The example in the textbook displays all the areas in order because the input is such that will cause the in order output. Your program should display all circles in order even when the input for radii is not in any particular order. // This program uses an array of objects. // The objects are instances of the Circle class. #include <iostream> #include <iomanip> #include "Circle.h" // Circle class declaration file using namespace std; const int NUM_CIRCLES = 4; int main() { Circle circle[NUM_CIRCLES]; // Define an array of Circle objects // Use a loop to initialize the radius of each…
