HELP plse

Hi, I am trying to make a grade management program and I have everything but my sort function is not working and I am getting a parse error at the end of input.. Could someone please help... Thanks

Code:

---

  #include <stdio.h>
  #include <string.h>
  #include <stdlib.h>

  void readfile(char name, int grade1,int grade2,int grade3);
  int meangrade(int grade1,int grade2,int grade3);
  void display(char name, int grade1,int grade2,int grade3);
  int qsort(char name, int grade1, int grade2, int grade3, int
meangrade);
    struct grades
    {
    int grade1;
    int grade2;
    int grade3;
    };

      struct grades name[30], g1, g2, g3,*gptr;

      FILE *infile;
      FILE *outfile;

  int main(int argc, char **argv) {
    {
    char filename;
    int choice, exam;
    FILE *infile = fopen("grade.txt", "r");
    FILE *outfile = fopen("grades.txt","w");

    printf ("Please enter the filename needed:  \n");
    scanf("%c", &filename);

    FILE *infile = fopen("grade.txt", "r");
    FILE *outfile = fopen("grades.txt","w");

    printf ("Please enter the filename needed:  \n");
    scanf("%c", &filename);
    printf("Please enter 1 for a specific exam to be displayed or 0 to exit. \n$
    scanf("%d", choice);
        if (choice == 0)
            display;
        else
            printf("Goodbye....\n");

        fclose(infile);
        fclose(outfile);

      return 0;
}
  void readfile(char filename,char name[30],int grade1,int grade2,int grade3){
      fscanf(infile,"%c %d%d%d", name[30], &grade1, &grade2,&grade3);
  }
  int meangrade(int grade1,int grade2,int grade3,int meangrade){
      meangrade = (grade1 +grade2 +grade3)/3;
      return meangrade;
    }
    }

      meangrade = (grade1 +grade2 +grade3)/3;
      return meangrade;
    }

  void display(char filename,char name[30], int grade1,int grade2,int grade3){
          int exam;
          printf("Which exam number would you like to see?    ");
          scanf("%d", &exam);
            if (exam > 3) {
                printf("Please enter a valid exam number:  ");
                scanf("%d", &exam);
            else
                fprintf(infile,"%s%d%d%d", name[30], &grade1,&grade2, &grade3);

      int exam;
          printf("Which exam number would you like to see?    ");

            else

        }
  }

        int qsort(char name[30], int grade1,int grade2,int grade3, int meangrad$
          int j, max;
          for( j = 0; j < 100; ++j) {
              if (name[j].grade1 > name[j].grade2)
                  max = name[j].grade1;
              else
                  max = name[j].grade2;
              if (name[j].grade3 > max)

                  max = name[j].grade3;
          return qsort;
        }
  }

Have you looked at your post? I am not sure what you did but it is all messed up. Why don't you try cleaning it up a bit and then maybe someone will look at it.

Hope this is better:

Your indenting is horrible.

Code:

---

int qsort(char name[30], int grade1,int grade2,int grade3, int meangrad$
/* missing something? */
    int j, max;
    for( j = 0; j < 100; ++j) {
        if (name[j].grade1 > name[j].grade2)
            max = name[j].grade1;
        else
            max = name[j].grade2;
        if (name[j].grade3 > max)
            max = name[j].grade3;
        return qsort;
    }
}

---

See what good indenting does for you? I've hilighted the problems. You should be able to fix it from there.

Quzah.

still having issues with the sort function.

Can you be a little more specific?

I am getting the following errors when I compile my code above and I can't figure out what is the problem.

Code:

Have you looked at your function for your sort. Lets take a look:

Code:

---

int qsort(char name[30], int grade1,int grade2,int grade3, int meangrad$

---

To me and your compiler that means you are passing an array of 30 characters, not your structure. Your definition would need to be like:

Code:

---

int qsort( struct grades name[30], int grade1,int grade2,int grade3, int meangrad$

---

Code:

---

grades.c: In function `display':
grades.c:69: parse error before "else"

---

Well lets look at display, hmm.

Code:

---

if (exam > 3) {
      printf("Please enter a valid exam number:  ");
      scanf("%d", &exam);
      }else
      fprintf(infile,"%s%d%d%d", name[30], &grade1,&grade2, &grade3);

---

You are forgetting to close out your if statements. You have done this throughout that function. Try fixing those.

Code:

---

grades.c: In function `main':
grades.c:87: parse error at end of input

---

hmmm, lets look at the scanf....

Code:

---

scanf("%d", &choice);
