Answer:

SOLID is the acronym form of the first five principle of object oriented programming. It basically provide the high cohesive units and used in the testing purpose. The SOLID principle combined together to develop a software easily and it is easy to maintain.

By applying the SOLID principle it makes easy to understand it also provide the better quality in the software. Therefore, violating the SOLID principle it become difficult the code to test.

tatiyna

Answer:

input.open("rawdata");

input>>datum;

input.close();

Explanation:

ifstream objects maintain a filebuf object as their internal stream buffer, and perform operations like input/output on the available associated files.

In above statements.

input.open("rawdata");

The associated file named rawdata is opened.

input>>datum;

The integer from the file is read into already declared variable datum.

input.close();

Input stream is closed.

Over the past three hours the pressure has been steadily increasing at a rate of what

Lyrx [107]

Answer:

We need to find first the location, and then we need to note down the barometric pressure of each hour in tenth place without decimal like 1013.3 mb is equal to 133 and so on. And the rate can be steadily increasing, steady, steadily decreasing, steadily increasing and then falling, steadily falling and then increasing, and so on. To find the rate of increase in barometric pressure, we need to find the rate of change of barometric pressure, and this will be clear if we prepare the chart of the barometric pressure of each hour during the past three hours. The graph plotted will give us a clear indication through its slope.

Unlike memory, this type of storage holds data and programs even after electrical power to the computer system has been turned o

Scrat [10]

Answer:

Secondary memory.

Explanation:

Unlike main memory which loses its content when electrical power to the system is turned off, secondary memory is volatile and persistent in nature. i.e it retains its content whether or not power is supplied to the computer that is holding it. As a matter of fact, they (secondary memory) are meant to store data permanently. Examples of such memory are the hard drives, floppy disks, flash drives, CDs and CDROMs.

Also, unlike the primary or main memory that can be accessed directly by the processor of the computer housing it, secondary memory are not accessed directly.

Given class triangle (in files triangle.h and triangle.cpp), complete main() to read and set the base and height of triangle1 an

kow [346]

The C++ program that would complete the main () and set the base and height of triangle1 and of triangle2 is:

main.cpp

#include <iostream>

#include "Triangle.h"

using namespace std;

int main()

{

Triangle Tri1;

Triangle Tri2;

double base1, height1, base2, height2;

cout << "Enter a base for your Triangle1: ";

cin >> base1;

cout << "Enter a height for your Triangle1: ";

cin >> height1;

cout << endl;

cout << "Enter a base for your Triangle2: ";

cin >> base2;

cout << "Enter a height for your Triangle2: ";

cin >> height2;

cout << endl;

cout << "################################" << endl;

cout << "Triangle with larger area:" << endl;

if ((0.5)*base1*height1 > (0.5)*base2*height2){

Tri1.setValues(base1, height1);

Tri1.getValues();

cout << "Area: " << Tri1.getArea() << endl << endl;

}

else{

Tri2.setValues(base2, height2);

Tri2.getValues();

cout << "Area: " << Tri2.getArea() << endl;

}

return 0;
