Answer:
Following are the code to the given question:
#include <iostream>//header file
using namespace std;
class Window //defining a class Window
{
private:
int width, height;//defining integer variable
public:
friend ostream& operator << (ostream& stm, Window& width)//defining a friend function that takes two parameters
{
return stm<<"a ("<<width.width<<" x "<<width.height<<") window"; //use return keyword that return its values
}
Window(int width, int height): width(width), height(height)//defining parameterized constructor that inherit width and height in its parameters
{}
};
int main() //Main method
{
Window w(80,90);//calling class constructor
cout<<w;//print object value
return 0;
}
Output:
a (80 x 90) window
Explanation:
In the above code, a class "Window" is defined that uses a friend function "ostream& operator" is declared that uses the "ostrea&" as a data type to hold two-variable "stm and w" in its parameter, and declared the parameterized constructor to hold value by inheriting width and height in its parameters.
Inside the main method, a class object is created that calls the constructor and uses the print method to print object value.
Answer:
<h2>A negative impact.</h2>
Explanation:
The unemployed are also unable to purchase as many goods, so will contribute to lower spending and lower output. A rise in unemployment can cause a negative multiplier effect.
The script that Andy would want to use is Javascript, here is the source code: document.getElementById("para1").innerHTML = formatAMPM();
function formatAMPM() {var d = new Date(), minutes = d.getMinutes().toString().length == 1 ? '0'+d.getMinutes() : d.getMinutes(), hours = d.getHours().toString().length == 1 ? '0'+d.getHours() : d.getHours(), ampm = d.getHours() >= 12 ? 'pm' : 'am', months = ['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec'], days = ['Sun','Mon','Tue','Wed','Thu','Fri','Sat'];return days[d.getDay()]+' '+months[d.getMonth()]+' '+d.getDate()+' '+d.getFullYear()+' '+hours+':'+minutes+ampm;<span>}
The HTML code needed to call this Javascript on his website is this: </span><span><div id="para1"></div>
</span>
You could call the Javascript up using PHP.
Hope this helps! Good luck! :)
