Question

5.23 LAB: Miles to track laps

One lap around a standard high-school running track is exactly 0.25 miles. Write a program that takes a number of miles as input, and outputs the number of laps.


Output each floating-point value with two digits after the decimal point, which can be achieved by executing

cout << fixed << setprecision(2); once before all other cout statements.


Ex: If the input is:


1.5

the output is:


6.00

Ex: If the input is:


2.2

the output is:


8.80

Your program must define and call a function:

double MilesToLaps(double userMiles)

has to be done in c++

Answer 1

Answer:

Following are the code to this question:

#include <iostream>//defining header file

#include <iomanip> //defining header file

using namespace std;

double MilesToLaps(double userMiles)//defining method MilesToLaps which accepts parameter  

{

   double numlaps; //defining double variable

   numlaps = userMiles / 0.25; //calculating and holding numlaps value

   return numlaps; //return value

}

int main() //defining main method

{

   double userMiles;//defining double variable userMiles

   cout<<"Enter miles value: ";//print message

   cin>>userMiles;//input value

   cout<<fixed<<setprecision(2);//using setprecision method

   cout<<"Total laps: "<<MilesToLaps(userMiles);//print MilesToLaps method value

   return 0;

}

Output:

Enter miles value: 1.5

Total laps: 6.00

Explanation:

Description of the above code:

• In the above program, a double method "MilesToLaps" is declared, which accepts "userMiles" a double variable in its parameter. Inside the method, a double variable "numlaps" is declared, which divides the "userMiles" value by 0.25 and returns its value.
• In the main method, a double variable "userMiles" is declared that inputs value from the user end and use the setprecision and call the method "MilesToLaps"  and prints its return value.

Answer 2

Answer:

def miles_to_laps(miles):

  return miles / 0.25

miles = 5.2

num_of_lap = miles_to_laps(miles)

print("%0.2f miles is %0.2f lap(s)" % (miles, num_of_lap))
