Answer:
Logical Expressions
Explanation:
The expressions that have logical statements which could be "true or false" are known as logical expressions. These types of expressions are also known as Boolean Expressions.
These expression are used in computer programming. The purpose of these expressions in programming is to make a decision that could be based on different conditions. These conditions could be true or false. This is the main reason that. logical expression makes best sense for values received in true or false.
When a computer restarts without a hardware power-down-power-up cycle, it is doing an update.
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.
