help with computing average with arrays and functions

[rwswfan]

I'm having trouble writing code. The purpose of the lab is to gain experience with passing arrays in the parameter list. The user is asked to enter the n scores of N# of students (both arrays). The problem I'm having is how do I pass the value of lowest to the function computeaverage. The parameters cannot be deviated. The program is to drop the lowest score and compute the average. Please help.....


#include <iostream>
using namespace std;



float ComputeAverage(int, float []);
bool MoreStudents();
int GetNumberExams();
void GetExamScores(int, int, float[]);


int main()
{
float CourseGrades[35]; // Array of computed exam averages.
int NoStudents = 0; // Count of the number of students.
float ExamScores[10]; // Array of exam grades for a student.
int NoExams = 0; // Number of exams for the current course.

NoExams = GetNumberExams(); // Access the number of exams per student.

// Each time through this loop, the exam grades for one more student
// will be entered and processed.
do {
// Enter the exam grades for the current student. The grades
// are placed in the array ExamScores.
GetExamScores(NoExams, NoStudents, ExamScores);

// Compute the average score, after dropping the lowest.
// The average is placed into the next element of the
// CourseGrades array.
CourseGrades[NoStudents] = ComputeAverage(NoExams, ExamScores);

NoStudents++; // Increment the student count.

} while (MoreStudents()==true); // Loop as long as there are more students.

// Each time through this loop, the average grade for another
// student is output.
for (int i = 0; i < NoStudents; i++)
{
cout << "\nStudent " << i + 1 << ": ";
cout << CourseGrades[i];
}

cout << endl; // Flush the console buffer.

return 0; // Exit the program.
}

int GetNumberExams(int number)
{
cout<<"How many exams are there for this course: ";
cin>>number;
return number;
}

void GetExamScores(int nostud, int noex, float exscore[])
{
int n=0;
float sum=0.0f;
float lowest=100.0f;
cout<<"For student "<<nostud+1;
do
{
cout<<"Enter exam score "<<n+1<<":";
cin>>exscore[n++];
sum+=exscore[n];
if (exscore[n]<lowest);
lowest=exscore[n];
} while(n<=noex);
}

bool MoreStudents(bool response)
{
char resp;
cout<<"Are there more students?\nEnter a Y or N: --------> ";
cin>>resp;
resp=toupper(resp);
if (resp='Y')
response=true;
else
response=false;
return response;
}


float ComputeAverage(int NoExams, float ExamScores[])
{
return (sum-lowest)/(NoExams-1);


}

Go through. Check if the first element is larger or smaller. If it's smaller, set it to a temp value. check that temp value with the 3 element, if the third element's larger, set that as the temp value, else keep that past value, etc.

I've update the code. Is the location of sum correct? do I want it in computeaverage or getscores? If it's in getscores how do I pass a value to computeaverage (void function)?

#include <iostream>
using namespace std;



float ComputeAverage(int, float []);
bool MoreStudents();
int GetNumberExams();
void GetExamScores(int, int, float[]);


int main()
{
float CourseGrades[35]; // Array of computed exam averages.
int NoStudents = 0; // Count of the number of students.
float ExamScores[10]; // Array of exam grades for a student.
int NoExams = 0; // Number of exams for the current course.

NoExams = GetNumberExams(); // Access the number of exams per student.

// Each time through this loop, the exam grades for one more student
// will be entered and processed.
do {
// Enter the exam grades for the current student. The grades
// are placed in the array ExamScores.
GetExamScores(NoExams, NoStudents, ExamScores);

// Compute the average score, after dropping the lowest.
// The average is placed into the next element of the
// CourseGrades array.
CourseGrades[NoStudents] = ComputeAverage(NoExams, ExamScores);

NoStudents++; // Increment the student count.

} while (MoreStudents()==true); // Loop as long as there are more students.

// Each time through this loop, the average grade for another
// student is output.
for (int i = 0; i < NoStudents; i++)
{
cout << "\nStudent " << i + 1 << ": ";
cout << CourseGrades[i];
}

cout << endl; // Flush the console buffer.
system("pause");
return 0; // Exit the program.
}

int GetNumberExams()
{
int number;
cout<<"How many exams are there for this course: ";
cin>>number;



return number;
}

void GetExamScores(int noex, int nostud, float exscore[])
{
int n=0;
cout<<"For student "<<nostud+1<<"\n";
do
{
cout<<"\tEnter exam score "<<n+1<<":";
cin>>exscore[n++];
}
while(n<noex);

}

bool MoreStudents()
{
char resp;
bool response;
cout<<"Are there more students?\nEnter a Y or N: --------> ";
cin>>resp;
resp=toupper(resp);
if (resp=='Y')
response=true;
else
response=false;
return response;
}


float ComputeAverage(int NoExams, float ExamScores[])
{
int n=0;
float sum=0.0f;
float lowest=100.0f;
sum+=ExamScores[n];
if (ExamScores[n]<lowest);
lowest=ExamScores[n];
return (sum-lowest)/(NoExams-1);
}
