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:
algorithm.
Explanation:
An algorithm can be defined as a standard formula or procedures which comprises of set of finite steps or instructions for solving a problem on a computer. The time complexity is a measure of the amount of time required by an algorithm to run till its completion of the task with respect to the length of the input.
Furthermore, the processing symbols and their functions used in developing an algorithm are oval (start or stop), diamond (decision-making), circle (on-page connector), parallelogram (input and output), rectangle (calculation), arrow (flow or direction) and pentagon (off-page connector).
Some of the characteristics of an algorithm include the following;
I. An algorithm can be written using pseudocode. A pseudocode refers to the description of the steps contained in an algorithm using a plain or natural language.
II. An algorithm can be visualized using flowcharts. A flowchart can be defined as a graphical representation of an algorithm for a process or workflow.
In conclusion, an algorithm is a sequence of precise instructions which result in a solution for solving problems using a computer system.
Answer and Explanation:
Some of the negative aspects of robots at work place:
- Lesser flexibility
- Higher maintenance and installation cost
- Future insecurity and risk if the system malfunctions
- A decline in the opportunities for humans
- Unemployment as a result of automation and robot regulated work place.
Some of the positive aspects of robots at work place:
- Higher accuracy
- Higher speeds
- More work in less time
- Productivity and hence efficiency will increase
- Cost of some operations is reduced.
- Ease of employing in dangerous and hazardous fields by using specific robots for each task
Statement A is true. R4 is not part of the circuit since it has one terminal not connected. The other resistors are in series, so the same current flows through them. Hence they will dissipate equal power.
The answer to the question is c
