NOTE: in mathematics, division by zero is undefined. So, in C , division by zero is always an error. Given a int variable named

Sergio [31]

Answer:

#include <stdio.h>

int main()

{

int callsReceived, operatorsOnCall;

scanf("%d", &callsReceived);

scanf("%d", &operatorsOnCall);

if(callsReceived>=0 && operatorsOnCall>0)

{

printf("%d",callsReceived/operatorsOnCall);

}

else

{

printf("INVALID") ;

} }

Explanation:

The programming language to use here is C.

There is an int type variable named callsReceived

Another int type variable is operatorsOnCall

scanf is used to read values into callsReceived and operatorsOnCall

printf is used to print the number of calls received per operator which is found by dividing the calls received with the operators on call i.e. callsReceived / operatorsOnCall

Here the callsReceived is the numerator and should be greater than or equal 0 and operatorsOnCall is the denominator and should be less than 0. So an IF condition is used to check if the value stored in operatorsOnCall is greater than 0 and if the value stored in callsReceived is greater than or equal to 0 in order to precede with the division. AND (&&) logical operator is used to confirm that both these conditions should hold for the IF statement to evaluate to TRUE.

In case the input is not valid, the else part is displayed which means that the message INVALID will be displayed.

In C++ cin is used to read from callsReceived and operatorsOnCall and cout is used to display the results of division or the INVALID message in case the IF condition is false. Rest of the code is the same.

cin >> callsReceived;

cin >> operationsOnCall;

if(callsReceived>=0 && operatorsOnCall>0)

cout << (callsReceived/operationsOnCall);

else

cout << "INVALID";

What are the basic characteristics of object-oriented analysis and design (OOAD)? How does OOAD compare to structured analysis a

juin [17]

Answer:

Basic characteristics of OOAD and compression with SAD can be defined as follows:

Explanation:

The Object-oriented analysis is described as a design and analysis system like an application, that uses Oops programming. It is the measurement model, that is the presentation, which became a part of the object-based review.

The features of OOAD can be defined as follows.

The complex issues are simply solved.
The operation of very fast recovery.
The stability in condition changes.
Its conceptual method for resolving its extremely complex problems.

The difference in OOAD and SAD can be defined as follows:

The OOAD mainly focuses upon the design of objects, it can be used in highly complex logical systems, whereas the SAD focuses on data analysis systems and processes.
The OOAD uses the framework to target data, but the SAD is process-oriented. It uses class and UML diagrams, but SSAD uses DFDs to extract the element, it has many limited steps to prepare and execute, but OOAD relies mostly on initial growth. This method is being developed in the course of the process.

What are the three general methods for delivering content from a server to a client across a network

Tju [1.3M]

Answer:

Answered below.

Explanation:

The three general methods consist of unicasting, broadcasting and multicasting.

Casting implies the transfer of data from one computer (sender) to another (recipient).

Unicasting is the transfer of data from a single sender to a single recipient.

Broadcasting deals with the transfer of data from one sender to many recipients.

Multicasting defines the transfer of data from more than one sender to more than one recipients.

When writing test methods, what functionality is verified by the system method "runAs()"?

olchik [2.2K]

Answer:

The main functionality verified by this test method command is user sharing record.

Explanation:

Generally, every apex code runs in system mode.

Apex is strong object-oriented programming language that allows the developers to execute flow and transaction control.

Using syntax which look like java and acts as databases, Apex allows the developer to add any type of business logics to an event which can include button, clicks records or visual pages.

Apex code can be initiated by web service request.

The permissions and record sharing of current user are not consider by apex codes.

Now the system method runAs() will allow you to take or write a test method which will basically change the user context to an existing or an new user, so that the record sharing will take place.

runAs() command will not change or anything done with user permissions or permission levels, it will only record sharing of the user.

When you use runAs() command the original and true context will run after the test method is once completed under the command of runAs().

The runAs() has no concern with the user license.

If there is no or expired your personal or organization license you can just make a new user with this runAS() command.

In using this command we have to make a private class by the name of this test and then our further code to make a user , afterwards which we will the true and original code of ours which we want to run.

There are many other uses of runAs() like

 Mixed DML operations in test by opening the DML operations.

 We can also use it as a version which will take a package as a version argument. This will cause the code a specific version.

runAs(System.Version) is the command used for this.
