I need help with this program. here is what we are supposed to do.
The program should prompt the user to 'Please enter numeric grade: '.

The program will then pass the numeric grade to a function that will convert to a letter grade. This function should have the following prototype:

char get_letter_grade (int grade_num);

100-90 A

89-80 B

79-70 C

69-60 D

below 60 F

4. The character that is returned will then be sent to a function to determine if the letter grade is passing (grades higher than 59 are passing). This function should have the following prototype:

bool is_passing(char grade_letter);

5. Your program should then display the results. For example:

Please enter numeric grade: 83

The letter grade is: B.
The grade is passing.

Here is what i have so far.

#include <fstream>
#include <iostream>

using namespace std;

int main()
{
int grade_num;

cout<< "Please enter numeric grade:"<< endl;
cin>> grade_num;
return 0;
}

char get_letter_grade (int grade_num)

{
if (grade_num<=60);
cout<< "The letter grade is F"<< endl;
else if ( grade_num<=69);
cout<< "The letter grade is D"<< endl;
else if (grade_num<=79);
cout<< "The letter grade is C"<< endl;
else if (grade_num<=89);
cout<< "The letter grade is B"<< endl;
else (grade_num<=100);
cout<< "The letter grade is A"<< endl;
return (grade_num);
}

bool is_passing(char grade_letter)

{

Please use code tags
Remeber you are working with a specific range so you are going to need to use the && in your get letter grade function. Also that function needs some other adjustments. You also need to call it from main. Did you even go to class?

the answer to this is in my old C++ book, it has the same questions as an example

i don't have to book with me, but i'll try to put it up tomorrow

This solution won't work for you, but it should give you a push in the right direction:

I'd like to point out that these solutions are no better or worse than anyone elses, but rather a demonstration of different ways to solve the problem and still get the same result.



or Needs tweeking if grade is 100 or less then 60

Thanks for all of the help. We get little to no help from the TA's in our classes and yes i do go to class, it's hard to learn when they do not teach what you need to know.

You realize you're paying to be taught, right? Don't just sit there and whine about the instructors not doing their part, make them do it.

ONE HELL OF A POINT...i'll have to remember that "intensely" if i get accepted to grad school

int main(){

int grade;

grade = 0;

cout << "Enter grade: ";
cin >> grade;

{
if (grade >= 90)
cout << "A";
else if (grade >= 80)
cout << "B";
else if (grade >=70)
cout << "C";
else if (grade >= 60)
cout << "D";
else
cout << "F";
}
return 0;
}

i don't know if that will work, its been way to long since writing code

>i don't know if that will work
So run it and see. If you aren't confident that your code is 100% correct, don't write directly to the thread. Write the code in an editor, compile it, run it, debug it, and make sure it's working like you expect before posting it.

To this day, I still test my code before posting it 9 times out of 10. I'm confident that it's flawless (though part of that is ego), but I still would rather double and triple check myself than have somebody else correct a stupid mistake.
