Write a function and name it add_four_nums that takes in 4 parameters as integers (no strings), calculates their sum, and displays it in an alert box?

4. Write a function with no parameters. In that function, add the numbers from the textboxes with the ids: boxA and boxB and write the result to the textbox with the id boxC?

Add a function to get the CPI values from the user and validate that they are greater than 0. 1. Declare and implement a void function called getCPIValues that takes two float reference parameters for the old_cpi and new_cpi. 2. Move the code that reads in the old_cpi and new_cpi into this function. 3. Add a do-while loop that validates the input, making sure that the old_cpi and new_cpi are valid values. + if there is an input error, print "Error: CPI values must be greater than 0." and try to get data again. 4. Replace the code that was moved with a call to this new function. - Add an array to accumulate the computed inflation rates 1. Declare a constant called MAX_RATES and set it to 20. 2. Declare an array of double values having size MAX_RATES that will be used to accumulate the computed inflation rates. 3. Add code to main that inserts the computed inflation rate into the next position in the array. 4. Be careful to make sure the program does not overflow the array. - Add a...

Create a function named fnTuition that calculates the tuition for a student. This function accepts one parameter, the student ID, and it calls the fnStudentUnits function that you created in task 2. The tuition value for the student calculated according to the following pseudocode: if (student does not exist) or (student units = 0) tuition = 0 else if (student units >= 9) tuition = (full time cost) + (student units) * (per unit cost) else tuition = (part time cost) + (student units) * (per unit cost) Retrieve values of FullTimeCost, PartTimeCost, and PerUnitCost from table Tuition. If there is no student with the ID passed to the function, the function should return -1. Code two tests: 1) a student who has < 9 student units, and 2) for a student who has >= 9 student units. For each test, display StudentID and the result returned by the function. Also, run supportive SELECT query or queries that prove the results to be correct.

In Python, changing a mutable parameter directly inside of a function is considered creating a side effect. True or false?

Write a set of functions that calculate the cost of movie tickets for a family. These functions should use a pass-by-reference variable that accesses the double running_total variable in main(). Using a loop, keep displaying the ticket prices for each age group: Something like: Model Hall Movie Ticket Box Office Under Age 3 (free) Ages 3-11 (10ドル.25) Ages 12-54 (15ドル.50) Age 55 or older (12ドル) If 4 tickets are purchased (not counting under age 3) then 20% discount Within the loop: Keep asking the user to input the moviegoer age and to enter a zero for the age when they are finished inputting all the family members. Also, within the loop: Keep a running_total that is output to the screenafter each age has been entered. This running_total should be accessed through the functions using apass-by-reference variable. Finally, after the looping is done: Calculate the total cost, including a 7.5% sales tax, and output it to the screen.

Write a function named product that takes two int parameters and returns the product of those two integers. Here is an example: int n = product(7, 5); // n is 35 We are providing a test framework that, if you wish, you may use with a compiler to test your function. What you will submit as your answer to this problem is only the product function. Do not submit things like the #include lines or a main routine. If we take the code you write in the space below and insert it into the program, the resulting program must build without compilation errors (mere warnings are allowed). You do not need to write comments in the code; we will not look at any comments. Here is the test framework that you may copy and paste into a C++ source file. For your own testing purposes, you might add additional tests in the main routine, although you won't be turning them in, of course. #include <iostream> #include <cassert> using namespace std; // SUBMIT AS YOUR ANSWER ONLY THE CODE BETWEEN THIS...
