Question
Can someone help me to explain this? This is a pastime question. The answer is (C), which is 101, but I don't understand why.
Question:
Assume the following function has been implemented.
def descript(num: int)-> str:
"""Return "High" if num is greater than 100, return "Low" if num
is between 0 and 100 inclusive, and return "Neg" otherwise
"""
Also assume that the implementation has been tested on the inputs: 500, 100, 0, -1, -50. Which of the
following inputs would be the least redundant for testing purposes.
A. 0
B. 50
C. 101
D. 1000000000
E. They are all equally redundant.

- Consider the function definition below. Assume x = 5, y = 3 and j = 8 as the function starts. Which variables will change after the function finishes? void findout (int &x, int y, int &j) { for (int i = 1; i 5) { x = 2*x - 3*y; y = 4 + 3 x; } else { Oi y = 2*x - 3; x = 4 + 3% y; } } // end of for loop x and y y All three since the first and last are references. x and jarrow_forwardFor 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円') {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; };arrow_forwardComplete 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"') ])arrow_forward
- Please write the correct code for this question. I really don't know what can be changed.arrow_forwardWrite 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...arrow_forwardC program: Please write a program with call to functions to produce the output given below: *********************************************** * MENU – Final Exam * * (1) Calling displayOddDigitInfo() * * (2) Quit * *********************************************** Enter an integer for option + ENTER: 6 Wrong Option! *********************************************** * MENU – Final Exam * * (1) Calling displayOddDigitInfo() * * (2) Quit * *********************************************** Enter an integer for option + ENTER: 1 Enter an integer: -294257 Calling displayOddDigitInfo() with argument of -294257 - While displayOddDigitInfo() is running – -294257 is negative and odd! -294257 has 3 odd digits of 7 5 9 *********************************************** * MENU – Final Exam * * (1) Calling displayOddDigitInfo() * * (2) Quit * *********************************************** Enter an integer for option + ENTER: 1 Enter an integer: -25904 Calling displayOddDigitInfo() with argument of...arrow_forward
