Help with sorting

[djustus1]

I hope I am postin gin the right spot.I am new to this site.
I need help with sorting the grades, please. Can anyone help?Thanks

include<iostream>
#include<iomanip>
using namespace std;



int main()
{
	double *grades;           //point used to point to an array that holds grad
	double total = 0.0;            // total of grades
	double average;              // holds the average grades
	int count;                 // loop counter
	int numGrades;			   //grades that will be processed

	//get the number of months
	cout <<"How many grades will be processed?" << endl;
	cin >>numGrades;

	//allocate memory for the number of grades
	grades= new double[numGrades];

	//Get the grades
	cout <<"enter the grades below."<< endl;
	for(count=0; count < numGrades; count++  )

	 {
	 cout << "Grade " << (count + 1) << ":";
	 cin >> grades[count];
	 }

	 //calculate the grades
	 for(count=0;count <numGrades;count++)
	 {
		 total += grades[count];
	 }
	 //calculate the average grades
	 average += total/numGrades;

	 //Display the results
	 cout << fixed <<showpoint << setprecision(1);
	 cout <<"\n\nTotal  Grades: " << total << endl;
	 cout <<"Average Grade: " << average << endl;

	 //Free dynamically allocated memory
	 delete [] grades;
	 grades= 0;

	 system("Pause");

	return 0;
}

you could use standard C function qsort(), c++ std::sort(), or write your own sort algorithm.

something is wrong with my bubble sort. Help from anyone. Thanks
