Thread: Ignoramus needs help with a Simple Grade program.

Hello Everyone, I'm new to this board. I'm taking a class of which I have not taken the prerequisite. I have never programmed before, and now I have a simple program due tomorrow, and I'm at a loss at how to do it. Here's the problem

“Write a program that predicts the score needed on a final exam to achieve a desired grade in a course. The program should interact with the user as follows:
Enter desired grade> B
Enter minimum average required> 79.5
Enter current average in course> 74.6
Enter how much the final counts
as a percentage of the course grade> 25
You need a score of 94.20 on the final to get a B.”

I have no idea how to deal with the letter 'B' How do I assign a value to it? How do I use printf and scanf with this variable? I can manage the numerical operations, but I just really need help with the letter part of this assignment. Please let me know if you need clarification. Thanks!

Code:

      1 # include <stdio.h>
      2
      3 int main ()
      4
      5 {
      6
      7     
      8     double desired, minimum, current, final;
      9     printf("Enter desired grade> ");
     10     scanf("%lf", &desired);
     11     printf("Enter minimum average required> ");
     12     scanf("%lf", &minimum);
     13     printf("Enter current average in course> ");
     14     scanf("%lf", &current);
     15     printf("Enter how much the final counts\n");
     16     printf("as a percentage of the course grade> ");
     17     scanf("%lf", final);
     18
     19 }

Hey everyone, I got the thing to work. Thanks for your help. The tutorial helped a lot, but now I have another question! I will create a new thread.

Please note that the OP clearly stated the specs, the problem, and also some code, in addition to their question. I personally don't see anything here that goes against the homework policy.
