Help With My C++ Program PLEASE?

Question

This is what I have now and I have 2 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.





#include
#include

using namespace std;


calculateGrade (float,average);

int main ()
{
ifstream infile;
infile.open("C:\inGrade.dat");





outfile << calculateGrade<< endl;


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




infile.close ();
outfile.close ();


system("pause");
return 0;

char calculateGrade (float average)
{
char grade;

if (average >= 80.0)
grade = 'A';
else if (average >= 70.0)
grade = 'B';
else if (average >= 60.0)
grade = 'C';
else if (average >= 50.0)
grade = 'D';
else
grade = 'F';
return (grade);
}






}

Answer 1

In your function prototype line, you need to define the return type, or you will get an error saying that two functions differ only in their return type. Also you have a comma between void and average. Get rid of it.

Also, when you call calculateGrade, you need to pass the argument.

I am not going to finish the program for you, but this should be enough to help you make some progress.

Answer 2

Why is calculateGrade inside main? Also you're using outfile before defining it.

"outfile << calculateGrade<< endl;


ofstream outfile;
outfile.open("C:\FinalGrades.t... "

When calling calculateGrade() you're not using the correct syntax or arguments..

"outfile << calculateGrade<< endl;"

When declaring calculateGrade you have a comma after the type 'float'

"calculateGrade (float,average);"

I recommend you pay more attention to the compiler error output as it will probably tell you most of that.

Ok, what exactly did you need help with in this program?
