C++! Help creating a user defined function that will exlcude the minimum and maxinum number. I just need the function not the whole program!

code:

//

// This function finds the minimum and maximum of a series of 5 numbers

// This function should have a void return type.

// You must use some reference parameters for this function.

//

// Write this function **********

//

void max_and_minimum (double ) { // incomplete and probably incorrect code

double num1, num2, num3, num4, num5;

cout

cin >> num1 >> num2 >> num3 >> num4 >> num5;

double minimum;

double max;

minimum = num1;

max = num5;

if ( minimum > num2) {

minimum = num2;

}

if (minimum > num3){

minimum = num3;

}

if (minimum > num4) { // end of incomplete and incorrect code

}

// Find the average of 5 numbers excluding the minimum and maximum

// If there is more than one number with the minimum or maximum value,

// only exclude the number one time. For example, if the numbers are:

// 4.5 6.7 2.3 7.8 2.3, the average is calculated using the numbers:

// 4.5 6.7 2.3.

//

// This function must call the above function that finds the minimum and maximum

// values in a series of 5 numbers.

//

// This function does not use reference parameters

//

// Write this function

// End of your code
