Answer:
#include <iostream>
#include<iomanip>
using namespace std;
double DrivingCost(double drivenMiles, double milesPerGallon, double dollarsPerGallon)
{
double dollarCost = 0;
dollarCost = (dollarsPerGallon * drivenMiles) / milesPerGallon;
return dollarCost;
}
int main()
{
double miles = 0;
double dollars = 0;
cout << "Enter miles per Gallon : ";
cin >> miles;
cout << "Enter dollars per Gallon: ";
cin >> dollars;
cout << fixed << setprecision(2);
cout << endl;
cout << "Gas cost for 10 miles : " << DrivingCost(10, miles, dollars) << endl;
cout << "Gas cost for 50 miles : " <<DrivingCost(50, miles, dollars) << endl;
cout << "Gas cost for 400 miles: "<<DrivingCost(400, miles, dollars) << endl;
return 0;
}
Explanation:
- Create a method definition of DrivingCost that accepts three input double data type parameters drivenMiles, milesPerGallon, and dollarsPerGallon and returns the dollar cost to drive those miles
.
- Calculate total dollar cost and store in the variable, dollarCost
.
- Prompt and read the miles and dollars per gallon as input from the user
.
- Call the DrivingCost function three times for the output to the gas cost for 10 miles, 50 miles, and 400 miles.

Explanation:
In the given java code, an integer variable "i" and an array number is defined, which size is 10, in the next step two for loop is declared, that can be described as follows:
- In the first loop, array use loop variable "i" use, which minus the value of 5 and multiplies by 2, and it will calculate the square of that number.
- In the next step, a for loop is declared, that prints these array number variable square.
Answer:
Worksheet ranges is a group of cells, and a value range like 25 to 340. It is used for data modeling. Like you can use it in the vlookup, Hlookup and Xlookup for looking up a column cell value in the mentioned worksheet range. Different worksheet's ranges of cells can also be used, and in any number from throughout the workbook, and that makes the analysis quite easy. Through work sheet ranges we get the control over all the cells as well as cells group. Whatever analysis we do, we do on the list of cells. And through the worksheet ranges we get the control over the cells. And thus, this is extremely useful definitely.
Explanation:
Like one worksheet range can be from top left corner to the bottom right corner. And this assigns whole worksheet as the worksheet range.
Its used in almost all the Excel formulas, and you must know it.
An example is:
Worksheets("Sheet2").Range(Cells(2, "B"), Cells(35, "B")).select
This selects the Range B2:B35 from Sheet 2.
Answer:
Explanation:
The constant function is useful in algorithm analysis, because it characterizes the number of steps needed to do a basic operation on a computer, like adding two numbers, assigning a value to some variable, or comparing two numbers. Executing one instruction a fixed number of times also needs constant time only.
