Answer:
#include <iostream>
using namespace std;
int main()
{
int length = 8;
int width = 8;
int perimeter = 2*(length + width);
int area = length * width;
cout<<"The perimeter is "<<perimeter<<endl;
cout<<"The area is "<<area<<endl;
return 0;
}
Explanation:
include the library iostream for using the input/output instructions in the c++ programming.
Create the main function and define the variable length and width with values.
Then, use the formula for calculating the perimeter and area of rectangle.


and store in the variables and finally print the output.
Answer:
dataFile << salary;
Explanation:
To write salary to a file (payroll.dat) using ofstream, you make use of the following instruction:
<em>ofstream dataFile;
</em>
<em>myfile.open ("payroll.dat");
</em>
<em>myfile <<salary;
</em>
<em>myfile.close();</em>
<em />
This line creates an instance of ofstream
<em>ofstream dataFile;
</em>
This line opens the file payroll.dat
<em>myfile.open ("payroll.dat");
</em>
This is where the exact instruction in the question is done. This writes the value of salary to payroll.dat
<em>myfile <<salary;
</em>
This closes the opened file
<em>myfile.close();</em>
<em />
<em />
You would have a total of 2.5 GB of capacity.
A gigabyte consists of 1000 megabytes, so 500 megabytes make half of a gigabyte, or 0.5 gigabytes.
So 2GB + 0.5GB = 2.5GB
<h2>The alignment of the text will be "left" by default</h2>
Explanation:
- In Excel or spreadsheet, if any number is entered, it will automatically be aligned to right because right alignment is preferable for the numbers.
- In case of any alignment is mentioned in the cell in prior to entering text or if the type of data is changed after or before entering the text, then the text is aligned accordingly.
- According to the given scenario, a number "25" is entered and it is converted to text. So a text format will preserve the alignment as entered. By default it will be "left" aligned.
