HELP with a C++ program reading students grades from an infile and outputing the results to outfile?

I have to write a program the reads students grades together with their test grades. It suppose to compute the average test scores an then assign the appropriate grade. have to use a void function to determine the average for the five test scores and a value returning function to determine and return each students grade. the students grades are on an infile and i have to output it to an outfile.





This is what i have:


#include %26lt;iostream%26gt;


#include %26lt;fstream%26gt;





using namespace std;











calculateGrade(float);


int main ()


{


ifstream infile;


infile.open("C:\inGrade.dat");














ofstream outfile;


outfile.open("C:\FinalGrades.txt");





calculateGrade()








infile.close ();


outfile.close ();








system("pause");


return 0;


}





void calculateGrade(string, float)


{


if (average%26gt;=90)


outfile%26lt;%26lt;"A"%26lt;%26lt;endl;


else if(average%26gt;=80)


outfile%26lt;%26lt;"B"%26lt;%26lt;endl;


else if (average%26gt;=70)
