4. Absolute Value Template
Write a function template that accepts an argument and returns its absolute value. The absolute value of a number is its value with no sign. For
example, the absolute value of -5 is 5, and the absolute value of 2 is 2. Test the template in a simple driver program being sure to send the
template short, int, double, float, and long data values.

Lowest Score Drop
Write a program that calculates the average of a group of test scores, where the lowest score in the group is dropped. It should use the following functions:
void getScore() should ask the user for a test score, store it in a reference parameter variable, and validate it. This function should be called by main once for each of the five scores to be entered.
void calcAverage() should calculate and display the average of the four highest scores. This function should be called just once by main and should be passed the five scores.
int findLowest() should find and return the lowest of the five scores passed to it. It should be called by calcAverage, which uses the function to determine which of the five scores to drop.
Input Validation: Do not accept test scores lower than 0 or higher than 100.
Usernames
An online company needs your help to implement a program that verifies the username chosen by a new user. Their rules is described below:
Username MUST contain at least 6 characters;
Username cannot start with a number;
Username can only contain letters or numbers.
If valid, the username may be resgistered if it doesn't already exist in the system.
You should not use built-in functions to determine the character type such as isnumeric() or islower().
Use the strings given alphabet and numeric to determine if each character is valid.
Use the list registered to help you determine if the username is already registered.
Don't forget to execute the cell below to use these strings
# run this cell to create these variablesalphabet = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'numeric = "0123456789"registered = ["john87", "topmage", "light4ever", "username2"]

- C++ Visual 2019 A particular talent competition has five judges, each of whom awards a score between 0 and 10 to each performer. 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.

"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.
