Question

Need help answering these questions

1. How does interactive processing differ from batch processing?

2. Discuss the importance of consistency in programming design.

3. Under what circumstances would you use a validation loop?

4. Discuss the meaning of the following sentence: Although functions, methods, and properties can yield the same results, their syntax differs.

Answer 1

1.) DIFFERENCE BETWEEN BATCH AND INTERACTIVE PROCESS

BATCH PROCESSING_____

a.) In Batch Processing  everything run simultaneously.

b.)There is no interaction with the user  or the system.

c.) We start the batch job or make a proper schedule for it for the future use.

d.) An example of a batch job is a cron job on a Linux system, which deletes different files in different directories.

INTERACTIVE PROCESSING_____

a.)In Interactive Processing we need  input from a user, a systems admin or from  another process running on the computer.

b.)User jobs and systems administrator jobs differ only in the level and the permissions granted for the task

c.) . An example of a process doing something interactively is asking a program to print off something, which then must call up a Print Spooler to do the task.

2.) IMPORTANCE OF CONSISTENCY IN PROGRAMMING DESIGN------

a.)It can be dfined  as sameness or  uniformity in design of the program.

b.) It  leads to code where you can make more assumptions and predictions about its behavior and implementation that end up being accurate.

c.) In the older systems we can’t fit the codebase in our mind and these guesses are critical tools developers use to feel their way around the system.

d.) The user can increase the number and frequency of correct assumptions by making your code consistent, and these correct assumptions (and verifications) lead to the many future steps that can leadto growth

e.)The code becomes more reliable and predictable.

f.) It makke the code easier to meta-program, automate, refactor, and test

3.) Circumstances  where we can use validating loop------

Validation loop come in light when the programmer need a specific range fo entering the data.

For example-- the marks obtained are always between 0 and 100 in your exam.

The user want to enter the marks

a.) if the marks are between 0 and 100 ,the marks will be displayed and added into the system

otherwise there will be a message that marks are out of range and again chance will be provided till marks entered are between 0 and 100

int marks;

cin>>marks;

while( marks<0 || marks>100)

{

cout<<"the marks are out of range";

cin>>marks;

}

cout<<marks;

4.) PROPERTIES,METHODS AND FUNCTIONS---

a.)These are the terms that are used for the varibles in the program for acheiving a goal and these are uesd differently with correspond to each other.

b.) They have different syntaxes due to the way that they are used.

c.) One is depend on the object and the other is not

d.) One can return thre data other may or may not.

e.) Some can be called directly and some need obnject to do so.
