Question

For each of the 4 functions below, Re-code each one to make it programmer friendly, using
standard coding conventions, and documentation.
Document each function with: a description of what it does (one sentence) and how it works (no
more than 3 sentences). Also, provide a precondition: and a postcondition: statement.
(See example for the setTime function below.)
1.
2.
setTime(int hours, int minutes, int seconds);
//Function to set the time
//The time is set according to the parameters
//Precondition: All parameters are valid numbers, within the range
of clock hours (1-12), minutes (0 - 59), and seconds (0 - 59).
//Postcondition: The clockType instance stores the hours, minutes
and seconds.
//
If any of the parameters are not valid the time
values will be set to zeros.
int _1 (double x) {return (int) (x + 0.5); };
int _2 (char* s) {char*t = s; while (*t!='\0') {t++; }return t-s;};
3.
long 3 (int x,int y) {long n=1; for (int i = 0;i < y;i++) {n*=x; } return
n; };

Which statement of the following is the most appropriate? Group of answer choices One good method for specifying what a function is supposed to do is to provide a precondition and postcondition for the function. One good method for specifying what a function is supposed to do is to provide a precondition and postcondition for the function. These form a contract between the programmer who uses the function and the programmer who writes the function. Using the assert function to check preconditions can significantly reduce debugging time, and the assertion-checking can later be turned off if program speed is a consideration.

2. Safir Market wants you to create a simple python program for calculating Total cost and change for their customers. The program should start by reading price, articles and Money. Then you need to do the following: • Create a void function that will display "Safir Market" • Create a function with return value and with parameters that will compute Total cost as product of articles and price • Create a function that will accept the computed Total cost as a parameter and will compute the change. If the Total cost is more than or equal to Money, the balance is to be calculated as Money - Total cost, otherwise print the message 'Money not enough' • Display the output as shown below, Sample output Enter the price: 345 Enter number of articles: 4 Enter Money: 65 -Safir Market Total cost is: 1380.0 Money not enough Change is: None

Complete the following TODO by defining a function called add_func(). Define a function called add_func() that takes two arguments. The function should adds the two arguments together using + and return the output. For example, if the input values for the arguments are 1 and 2, then 3 should be returned. Likewise, if the input arguments are "good" and " day", then "good day" should be returned. # TODO print(f"add_func output for 1 + 2: {add_func(1, 2)}") print(f"add_func output for good + day: {add_func('good',' day')}") todo_check([ (add_func(1,2) == 3,'add_func() did not return 3 when using input values 1 and 2.'), (add_func('good',' day') == "good day",'add_func() did not return "good day" when using input values "good" and " day"') ])

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…
