value returning in function

[shrina]

I have written this function to find the over all class average, so how can i pass the avg value to another function??

  double OverallClassavg (student details[])
{
	double total=0.0;
	double avg=0.0;

	for(int i=0; i < size; i++)
	{
		total += details[i].overall;
	}

	avg=total/size;

	cout<< "Over all class average : " << avg <<endl;

	return avg;
}

int main()
     double details[5] = {1, 2, 3, 4, 5};
     double averageAmount = OverallClassavg(details[]);
     std::cout << averageAmount << std::endl;

//or
     double details[5] = {1, 2, 3, 4, 5};
     std::cout << OverallClassavg(details[]) << std::endl;

How can i reuse the avg in another function??

example:

void listofStudentsAboveClassAvg (student details[], double avg)
{
	cout<< "List of students above the class average" <<endl;
	for (int i=0; i < size; i++)
	{
		if(details[i].overall < avg)
		{
			cout<<details[i].fname<<" "<<details[i].lname<< " - "<<details[i].overall<<endl;
		}
	}
}

like this??

um you would have to do

int maint()
{
listofStudentsAboveClassAvg(details[],OverallClassav(details[]));
}

or you can of course initialize a variable and set it equal to the class average and then put then use that as a paramater in your list of students above average function
