Describe the output when the following code executes in 64-bit mode: .data dividend_hi QWORD 00000108h dividend_lo QWORD 3330002

iragen [17]

Answer:

RAX = 333000h (16 bits with preceding zeros removed)

RDX = 20h (also 16 bits with preceding zeros removed)

Explanation:

The "div" opcode in the assembly language source code is used to divide operands. It accepts a divisor ( the denominator) and divides the content of the AX register. The result is saved in the AX register while the remainder (if any) is saved in the DX register. If the DX register holds any data, the data is replaced with the divisor remnant.

The code above divides the content of the RAX register with the divisor variable and saves the result and remainder in the RAX and RDX respectively.

marysya [2.9K]

Answer:

Option A: Software-as-a-service

Explanation:

Software-as-a-service (SAAS) is one of the cloud computing business models. The software is not delivered as a product hosted in the client machine. Instead, a customer just pays a subscription fee (sometimes free for limited quota) to gain access to the software which is hosted in a remote server maintainer by software vendor.

One benefit of SAAS is that the software vendor will usually responsible for software maintenance and update. The customer has no longer require to pay extra cost to upgrade the software. So long as the subscription is still valid, a customer can always access to the newest features of software.

Some examples of SAAS which is popular include DropBox, Google App, DocuSign, Microsoft Office 365 etc.

#include<string.h>

using namespace std;

int main()

{

//Variable to name and age of a person.

string name;

int age;

cout<<"Enter your name"<<endl;

cin>>name;

cout<<"Enter your age"<<endl;

cin>>age;

//Creating object of ofstream.

ofstream file;

file.open ("outdata.txt");

//Writing data to file named outdata.txt

file<<name<<" "<<age;

file.close();

}

Output:

Enter your name

John

Enter your age

Content of Output.txt:

John 25

Explanation:

To write data to a file ofstream object is used. An ofstream object file is created first and then using this object a file named "outdata.txt" is created.

Write a while loop that prints userNum divided by 2 (integer division) until reaching 1. Follow each number by a space. Example

jasenka [17]

Answer:

public class Main

{

public static void main(String[] args) {

int userNum = 40;

while(userNum > 1){

userNum /= 2;

System.out.print(userNum + " ");

}

Explanation:

*The code is in Java.

Initialize the userNum

Create a while loop that iterates while userNum is greater than 1. Inside the loop, divide the userNum by 2 and set it as userNum (same as typing userNum = userNum / 2;). Print the userNum

Basically, this loop will iterate until userNum becomes 1. It will keep dividing the userNum by 2 and print this value.

For the values that are smaller than 1 or even for 1, the program outputs nothing (Since the value is not greater than 1, the loop will not be executed).
