Write a c$++$ 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 beAfter dropping the lowest test score, the test average

is $68\mathrm{.}50$

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 findLowest that is passed the five test scores and then finds and returns 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 void 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:

$6524807351$

$6638846959$

$7252812353$

$6528726365$

$6555756862$

Submit the program and the output
