In C$++$

General requirements:

$-$ No global variables

$-$ No multiple return statements in one function

$-$ Show how you have tested these functions

$-$ You can use cin and cout in this function but please do not print out the results.

It should return the values to the caller through the use of return type and pass$-$by$-$reference parameters.

$-$ Please do not use struct, tuple or pair class.

Please use only pass$-$by$-$reference parameters and return type to return values to the caller.

$-$ Please do not use arrays. Please use only simple variables to keep track of the information.

Note: this is an exercise to use functions and not arrays.

Question #$1$:

Write a function named "readOnePIN" that reads in from the user a pin $($integer$)$ and ask the user re$-$enters the same pin to verify.

It will return the indicator of true or false $($match or not matched$)$ and the number of tries the user has attempted.

The user can enter the wrong pin up to only $3$ times.

Note: the function must return two separate values to the caller using return types and pass$-$by$-$reference parameters.

struct or tuple or pair is not allowed.

Printing is not allowed in the function. It can be done in the testing function or main.

Examples of the output of different program runs:

Please enter the pin: $1234$

Please re$-$enter the pin: $1234$

Matched: true

Number of tries: $1$

Please enter the pin: $1234$

Please re$-$enter the pin: $1111$

Unmatched.

Please re$-$enter the pin: $2222$

Unmatched.

Please re$-$enter the pin: $1234$

Match: true

Number of tries: $3$

Please enter the pin: $1234$

Please re$-$enter the pin: $1111$

Unmatched.

Please re$-$enter the pin: $2222$

Unmatched.

Please re$-$enter the pin: $3333$

Unmatched.

Match: false

Number of tries: $3$

Question #$2$:

Write a function named "countScores" that will accept a count as the total number of scores to be read in by the function.

After reading the list of scores $($integer$),$ it will return the following statistical data for those scores:

$-$ total scores minus the largest and the smallest

$-$ boolean flag indicating whether all scores are passing $($meaning greater or equal $70)$

Note: the function must return two separate values to the caller using return types and pass$-$by$-$reference parameters.

struct or tuple or pair is not allowed.

Printing is not allowed in the function. It can be done in the testing function or main.

Examples of output of different program runs:

If it is passing $5$ to the function

Please enter the scores: $1020304050$

Total scores: $90$

Passing: false

If it is passing $4$ to the function

Please enter the scores: $40506070$

Total scores: $110$

Passing: false

If it is passing $3$ to the function

Please enter the scores: $708090$

Total scores: $80$

Passing: true
