Tracking laps
Learning Objectives
In this lab, you will practice
writing functions, passing arguments and returning results from the function
printing the result of a function call
writing your code as a module
Instructions
Main Idea
An Olympic-size swimming pool is used in the Olympic Games, where the racecourse is 50 meters (164.0 ft) in length. "In swimming, a lap is the same as a length. By definition, a lap means a complete trip around a race track, in swimming, the pool is the race track. Therefore if you swim from one end to the other, you’ve completed the track and thus you’ve completed one lap or one length." (Source: What Is A Lap In Swimming? Lap Vs Length)
Write the function meters_to_laps() that takes a number of meters as an argument and returns the real number of laps. Complete the program to output the number of laps with two digits after the period.
Examples
Input:
150
Output :
3.00
Input:
80
Output:
1.60
Your program must define and call the following…
Void Do1 (int: &, a. int &b)
{
a = 5;
a = a + b;
b = a + 2;
}
Int main()
{
Int x = 10;
Do1 (x,x);
Cout << x << endl;
}
The output of this program is

Fractional scores, such as 8.3, are allowed. A performer's final score is determined by dropping the highest and lowest score received, then averaging the three remaining scores. Write a program that uses this method to calculate a contestant's score. It should include the following functions: void getJudgeData() should ask the user for a judge's score, store it in a reference parameter variable, and validate it. This function should be called by main once for each of the five judges. void calcScore() should calculate and display the average of the three scores that remain after dropping the highest and lowest scores the performer received. This function should be called just once by main and should be passed the five scores.

First,the program should ask if the patient was admitted as an in-patient or an out-patient.

If it is, it shouldbe re-entered before being returned.Once the required data has been input and validated, the program should use twoseparate functions to calculate the total charges.
