Chapter 5, Problem 31SA

explain the use of voids and why do we use it. explain also if else loops

Weighted Job Scheduling in C language only please Problem statement: You are given a list of jobs where each job has a start time, finish time, and the profit associated with that job, find the maximum profit subset of non-overlapping jobs.   Problem description: The problem wants you to find the maximum profit that you can make after performing a certain number of jobs such that each job has a certain condition that you can start a job only if the start time of the current job is greater than the finish time of the previous job. You are required to develop some algorithm such that the job start time and the finish time does not coincide with other jobs.   Output: (Attached photo)

Object-Oriented Programming ( Using Java Language) ----------------------------------------------------------------

Range for loop should be used even the block code needs to access index.  Group of answer choices True False

C++ programming Write a program that reads the grades of 3 students in three different courses and displays the average grade of each student in these three courses, as well as the average grade of all students.  You can use any loop method of your preference. (Hint: This is a nested loop technique)

In other words, describe the Pretest loop.

C++ Coding: Nested Loops Create a constant DIM. Set DIM to 7, and use a nested loop to display the following square matrix output. Output Example: -  -  -  X -  -  --  -  -  X -  -  --  -  -  X -  -  -X X X O X X X-  -  -  X -  -  --  -  -  X -  -  --  -  -  X -  -  -

LAB ASSIGNMENTS IMPORTANT: you should complete the PDP thinking process for each program. Turn in items: 1) book_list.py: you can adapt your Chapter 4 book_list.py Lab program. The program summarizes costs of a book list. It uses all of our standard mipo_ex features. In this version of the program you must use pylnputPlus functions to perform all the input validation and for the main() loop decision. Adjust your program to allow book prices to include $ and cents. Restrict individual book prices to $100 maxium. • Clearly document, with comments, your use of the pyip functions. This program summarizes a book liat. Enter the number of books that you need: Please enter a whole number: three Enter a number greater than 0: 3 Enter the name of book #1: The Mueller Report Enter cost of The Mueller Report, to the nearest dollar: Please enter a whole number: 18 Enter the name of book #2: Educated: A Memoir Enter cost of Educated: A Memoir, to the nearest dollar: Please enter a whole number: 24…
