Design
Considerations:
1. No global variables. All variables must be inside main().
2. Use three arrays: a one-dimensional array to store the students’ names, a (parallel)
two-dimensional array to store the test scores, and a parallel one-dimensional
array to store grades.
3. Your program must contain at least the following functions: a function to read and
store the data into two arrays, a function to calculate the average test score and
grade, and a function to output the results. Have your program also output the
class average.
4. You must read from the input file into the arrays. Make sure to pass the arrays
and the file stream variable (if needed) to the functions by reference.

5. Document the variables that are used and what their purpose is.

Explanation / Answer

ANS)Step1:program:

step2: it's exicted without errors

step3: you must need to enter one text file for input.

  #include <stdio.h>  #include <stdlib.h>  #include <math.h>        typedef struct  {      char fname[30];      char minitial[1];      char lname[100];      int q1, q2, q3, q4, mid, final;  } Student;        int main()  {      const int STUDENTSMAX = 100;         Student students[STUDENTSMAX];      int i = 0;                  char fname[30];         FILE *ifp, *ofp;  printf("Enter input .txt file name ");      scanf("%s",fname);      strcat(fname,".txt");         ifp = fopen(fname,"r");      ofp = fopen("output.txt", "w");               if(ifp == NULL)      {  printf("Error while opening the file. ");  exit(EXIT_FAILURE);      }      if (ofp == NULL)          {  printf("An error has been generated while attempting to open the output file");             fclose(ofp);          exit(1);          }         while(!feof(ifp))      {          fscanf(ifp, "%s, %s, %d, %d, %d, %d, %d, %d", students[i].fname, students[i].lname, &students[i].q1, &students[i].q2, &students[i].q3, &students[i].q4, &students[i].mid, &students[i].final);             printf("%s %s %d, %d, %d, %d, %d, %d  ", students[i].fname,students[i].lname,students[i].q1,students[i].q2,students[i].q3,students[i].q4,students[i].mid,students[i].final);     }         printf(" ");      printf(" ");      fclose(ifp);         }
