Code:
```//This still has 2 errors, asking for return values from
//calcaverage and from findlowest.  Can anyone help me?

//This program asks the user to pick the number of test
//scores they wish to average, drops the lowest(returning
//'lowestscore'and showing it) and then it calculates the
//average minus the lowestscore).  Could someone please
//take a look and let me know how to fix it.  THANKS !!!

/* You don't necessarily need to pass anything back to main.
It is probably better to calculate the lowest value first
and then call the function calculate average.
So no values are returned to main
*/

#include <iostream>

//functions
//The inside of the brackets tells you
//how many variables are being passed and
//if they are integers floats or arrays.
//Don't forget the ';'

int calcaverage(float [],int,float);
int findlowest(float [],int );

using namespace std;

int main()
{
float Scores[81];

findlowest(Scores,HowMany);

int stop;

return 0;
}

//This function finds the lowest score and returns it.
//Here you must declare what type they are
//For an array such as Scores you need to write float Scores[]
//The square brackets are needed/
//Note here you don't need the ';' at the end of the bracket
int findlowest(float Scores[],int HowMany)

}
}
//call function 'calaverage' passing the array
//'Scores'into it, 'howmany' and 'lowest'
calcaverage(Scores,HowMany,lowest);
//note it passes int three variables to 'calcaverage'
//Therefore the function declaration should
//have three variables as shown below

}

int calcaverage(float Scores[],int HowMany,float lowest)
{   float average;
float total=0;
for (int a=0; a<HowMany; a++)
{

{
total=total+Scores[a];

}
}

average=total/(HowMany-1);//-1 to ignore the lowest score
//therefore the array has shrunk by one.

cout<<"The average was "<<average<<endl;
}```

2. //This still has 2 errors, asking for return values from
//calcaverage and from findlowest. Can anyone help me?
the functions are ints. They must return values. Return 0 if you want to end the thing successfully but don't care to reference to the return value; or use void functions

3. Your calcaverage() and findlowest() functions are prototyped to resolve to returning an 'int'; however, neither function contains a single return statement. This is ok, but only if you prototype your functions to be 'void'.

example:

function prototypes:
Code:
```void calcaverage(float [],int,float);
void findlowest(float [],int );```
'void' lets your compiler know that the functions will not have any return value. Also, be sure to reflect the same changes in your function definitions as well.
