Answer: 443
Explanation:
Port 443 will need to be enabled for secure transactions to go through because it is the default port for HTTPS which is the transfer protocol for secure communication.
This way your credit card transactions will be encrypted to ensure protection from those who would seek to steal your data and your money.
Answer:
False
Explanation:
An abstract class is a class declared abstract — it may or may not include abstract techniques. It is not possible to instantiate abstract classes, but they can be sub-classed.
<u></u>
<u>Abstract method declaration</u>
abstract void moveTo(double X, double Y);
Usually the subclass offers solutions for all of the abstract techniques in its parent class when an abstract class is sub-classed. If not, however, the subclass must be declared abstract as well.
<u>Example</u>
public abstract class GraphicObject {
// declaring fields
// declaring non-abstract methods
abstract void draw();
}
I think it's C because he upgraded from a slower one
Answer:
Following are the program to this question:
#include<iostream> //defining header file
using namespace std;
int main() //defining main method
{
int sum = 0, num; //defining integer variable
cout << "Enter a number :"; // print message
cin >> num; //input number
sum=sum+num;
while (sum < 200) //defining loop that check sum value is less then 200
{
cin >> num; //input number by user
sum =sum+num; //add values
}
cout << "Sum = " << sum <<" the loop stops"; //print values
return 0;
}
output:
Enter a number :44
66
90
Sum = 200 the loop stops
Explanation:
In the given C++ program, the main method is declared, inside the method two integer variable "sum and num" is declared, in which sum variable assign a value, that is 0, and num is used to take input from the user end.
- In the next step, a sum variable adds num variable value and use a while loop that checks value is less than 200.
- In this condition is not true so, inside the loop, it takes value from the user and into the sum variable when its value is above 200, it will exit the loop and prints its total value.
