Write a program that calculates the average of a group of test scores, where the lowest score In the group is dropped. For example: If the user enters the values $65,43,78,67$ and $64,$ the output will be:

After dropping the lowest test score, the test average

$is68\mathrm{.}50$

This average is calculated by dropping the lowest score which is $43$ and dividing the sum of the remaining four values $65,78,67$ and $64,$ which is $274,$ by $4.$

It should use the following functions:

An int function getscore with no parameters, to ask the user for a single test score, validate it and return the score. The function should be called by the main function once for each of the five scores to be entered. Do not accept test scores lower than $0$ or higher than $100.$

An int function findiowest that is passed the five test scores and then finds and retums the lowest of the five scores passed to it$.$ It is called by function calcaverage, to determine which of the five scores to drop.

A float function calcaverage that is passed the five test scores and then calculates and returns the average of the four highest scores.

A vold function displayoutput that is passed the average score; it then displays the average of the test scores. Display two digits after the decimal point

You must submit the four functions you have developed as well as output using the following $5$ sets of input data:

$6524807351$

$6638846959$

$7252812353$

$6528726365$

$6555756862$
