Answer: ORG $3000 tell us that we want to load the program from the address $3000.

LDAA #$C2 tell us to load the value contained in the address present in the register C2 into the accumulator.

Explanation:

ORG instruction in microprocessor does not have a fixed address. It tell us where to begin the execution of the program by loading into a starting address space. It does not uses fixed addressing

LDAA instruction uses indirect addressing by placing the value from the address present in the register. Here the address is contained in register C2.

What was the first 1.0.1 version of openssl that was not vulnerable to heartbleed?

vovikov84 [41]

I suggest you to read OpenSSL changelogs to make it more clear. As there's not enough space to describe how it works. But heartbleed resistan version was 1.0.2, as I know.

1. Type a statement that reads a user-entered integer into variable numUsers. Assume scnr already exists.

ASHA 777 [7]

Answer:

Question 1:

int numUsers = scnr.nextInt();

Question 2:

public class OutputExample {

public static void main (String [] args) {

int numCars = 99;

Scannerscnr=new Scanner(System.in);

numCars=scnr.nextInt();

System.out.println("There are "+numCars+" cars");

return;

}

Question 3:

import java.util.Scanner;

public class Errors {

public static void main(String [] args) {

int userNum = 5;

System.out.println ("Predictions are hard. ");

System.out.print("Especially ");

System.out.print("about the future.");

System.out.println("Num is: "+userNum);

return;

}

Explanation:

In Question 1, the statement int numUsers = scnr.nextInt(); reads a new integer value from the keyboard and assigns it to the variable numUsers.

In question 2, Concatenation is used to format the print output.

In question 3, care is taken to fix each of the syntax errors (missing double quotes, semi-colon, concatenation)

Integers and booleans. Write a program RightTriangle that takes three int command-line arguments and determines whether they con

icang [17]

Answer:

The programming language is not stated;

I'll answer using C++

#include<iostream>

#include<cmath>

using namespace std;

int main()

{

int side1, side2, side3;

cout<<"Enter the three sides of the triangle: "<<endl;

cin>>side1>>side2>>side3;

if(side1<=0 || side2 <= 0 || side3 <= 0) {

cout<<"Invalid Inputs";

}

else {

if(abs(pow(side1,2) - (pow(side2,2) + pow(side3, 2)))<0.001) {

cout<<"Right Angled";

}

else if(abs(pow(side2,2) - (pow(side1,2) + pow(side3, 2)))<0.001) {

cout<<"Right Angled";

}

else if(abs(pow(side3,2) - (pow(side2,2) + pow(side1, 2)))<0.001) {

cout<<"Right Angled";

}

else {

cout<<"Not Right Angled";

}

return 0;

}

Explanation:

The following line declares the three variables

int side1, side2, side3;

The next line prompts user for input of the three sides

cout<<"Enter the three sides of the triangle: "<<endl;

The next line gets user input

cin>>side1>>side2>>side3;

The following if condition checks if any of user input is negative or 0

if(side1<=0 || side2 <= 0 || side3 <= 0) {

cout<<"Invalid Inputs";

}

If otherwise

else {

The following if condition assumes that side1 is the largest and test using Pythagoras Theorem

if(abs(pow(side1,2) - (pow(side2,2) + pow(side3, 2)))<0.001) {

cout<<"Right Angled";

}

The following if condition assumes that side2 is the largest and test using Pythagoras Theorem

else if(abs(pow(side2,2) - (pow(side1,2) + pow(side3, 2)))<0.001) {

cout<<"Right Angled";

}

The following if condition assumes that side3 is the largest and test using Pythagoras Theorem

else if(abs(pow(side3,2) - (pow(side2,2) + pow(side1, 2)))<0.001) {

cout<<"Right Angled";

}

If none of the above conditions is true, then the triangle is not a right angles triangle

else {

cout<<"Not Right Angled";

}

}

return 0;
