- The food pantry provides its volunteers with keys to unlock doors and a Food Pantry vest to let customers know they work there. There are a limited amount of keys and vests, so volunteers need to check them out of the office.Complete the program by creating a CheckoutEquipment function that takes in the number of keys and vests currently available at the office. If there are enough keys and vests, the function should reduce the number of keys and vests by 1 and return true. Otherwise, the number of keys and vests will stay the same, and the function will return false. Take note that the number of keys and vests will be defined in the main function and the CheckoutEquipment function should modify the values of those variables declared in main. #include <iostream> int main() { int keys = 10; int vests = 10; bool checked_out = CheckoutEquipment(keys, vests); if (checked_out) { std::cout << "Successfully checked out.\n"; } else { std::cout << "Not…5.11 LAB: User-Defined Functions: Max and min numbers Coral language only please Define a function named LargestNumber that takes three integers as parameters and returns the largest integer. Define a second function named SmallestNumber that takes three integers as parameters and returns the smallest integer. Then, write a main program that reads three integers as inputs, calls functions LargestNumber() and SmallestNumber() with the inputs as arguments, and outputs the largest and the smallest of the three input values. Ex: If the input is: 7 15 3 the output is: largest: 15 smallest: 3 Your program should define and call two functions:Function LargestNumber(integer num1, integer num2, integer num3) returns integer largestNumFunction SmallestNumber(integer num1, integer num2, integer num3) returns integer smallestNum1 - Nuclear Power Plant (python) The nuclear powerplant at Threeyedfish will automatically run a program to print a warning message when the reactor core becomes unstable. The warning message reads: NUCLEAR CORE UNSTABLE!!! Quarantine is in effect. Surrounding hamlets will be evacuated. Anti-radiationsuits and iodine pills are mandatory. Since the message contains crucial information, it should be printed three times. To do this, write a function that prints this message. This function has to be used three times.
- Exercise 9-6: Pass by Reference and Pass by Address In this exercise, you use what you have learned about passing arguments by reference and by address to functions to answer Questions 1-2. 1. Given the following variable and function declarations, write the function call and the function's header a. double price 22.95, increase .10; void changePrice(doubl e&, double); b. double price 22.95, increase .10; void changePrice (double*, double); c. int age = 23; void changeAge(int&); d. int age 23; void changeAge (int*); 2. Given the following function headers and variable declarations, write a function call: a. custNames [] = {"Perez", "Smith", "Patel", "Shaw"}; balances [] = {34.00, 21.00, 45.50, 67.00); void cust (string name [], double bal []) b. int values [] = {1, 77, 89, 321, -2, 34}: void printSum (int nums [])Program this on C .Write a function to convert temperature from Fahrenheit to Celsius named “ConvertFtoC” that takes one double value for Fahrenheit as argument, and returns the equivalent temperature in Celsius(type double). Create a program that exercise this function by obtaining a Fahrenheit value from the user, calling the function, and displaying the value of Celsius it returns. [Formula: Celsius = (Fahrenheit – 32 ) * 5/9 ]6. Write a function called tallEnough() that takes a single parameter, the user’sheight in inches. If the height is 48 or more, the function should return “You can go onthis ride.” Otherwise it should return the string “Sorry, you’re not tall enough.”>>> tallEnough(46)"Sorry, you're not tall enough.">>> tallEnough(48)'You can go on this ride.'
- 8. Write a function with one parameter. The function should accept the value of a radius as its argument and return the volume of the sphere with that radius. Note that the radius may be a decimal fraction. The function should not read or print anything.Write two or more function, parameters and arguments that generates a random license plate. Your function should have approximately equal odds of generating a sequence of characters for an old license plate or a new license plate. Write a main program that calls your function and displays the randomly generated license plate.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.
- 1. Write a function which takes one parameter int num, and prints out a countdown timer with minutes and seconds separated by a colon (:). It should print out one line for each second elapsed and then pause one second before printing out the next line. A few things to note: - You can assume that calling the function usleep(1000000) makes the program pause for one second - It should count down from num minutes:zero seconds to zero minutes:zero seconds - Your function must have the following signature: void timer(int num) You do not need to demonstrate calling this function from main(). You don't need to format the output nicely; the below is acceptable output for calling this function when minutes is 10: 10:0 9:59 9:58 … 9:1 9:0 8:59 8:58 … 0:2 0:1 0:0In this part your will have questions about C++ functions with pointers. • Write a function that takes three integer pointer as parameters and calculates sum of all numbers. This function must return the result as a pointer. • Declare a structure about a book which has properties such as name and price etc. Then create a list of book with 5 books. After that define a function that takes this book-list as a pointer and print out list items. • Write a function that calculates total price of the book in the book list (note: take the book-list as a pointer again). Write all function prototypes and test all functions within a single main functions.1. Write a function that converts a phrase into pig Latin. A word is convertedto pig Latin by removing the first character of the word, placing it at theback of the word, and adding the characters “ay” to the word. For example,“hello world” in pig Latin is “ellohay orldway.” Your function can assumethat each word consists of at least two letters and that each word is separatedby one space, with no punctuation marks.2. Write a function that counts the occurrences of a word in a string. Thefunction should return an integer. Do not assume that just one space separates words and a string can contain punctuation. Write the function sothat it works with either a String argument or a StringBuilder object.3. Write a function that takes a number, such as 52, and returns the numberas a word, as in fifty-two.4. Write a subroutine that takes a simple sentence in noun-verb-object formand parses the sentence into its different parts. For example, the sentence“Mary walked the dog” is parsed into…
