Example
 8: Write a C program to process student records using
 
structures.
Solution 8:
 The program is as follows:
#include
main( )
 {
   struct record
    {
      char name[30];
      char regno[12];
      float avg;
      int rank;
    } student[50], temp;
 
    int i, j, n;
    printf(“\n Processing student %d record…\n”, i+1);
    printf(“Student name? (type END to terminate) “);
    scanf(“%s”, student[i].name);
    printf(“%s\n”, student[i].name);
      while (strcmp(student[i].name, “END”) > 0)

---

       {
         printf(“Register number? “);
         scanf(“%s”, student[i].regno);
         printf(“%s\n”, student[i].regno);
         printf(“Average marks? “);
         scanf(“%f”, &student[i].avg);
         printf(“%f\n”, student[i].avg);
         i++;
         printf(“\n Processing student %d record…\n”, i+1);
         printf(“Student name? (type END to terminate) “);
         scanf(“%s”, student[i].name);
         printf(“%s\n”, student[i].name);
       }
      n = i;
      /* arranging student marks */
      for (i=0;i         for (j = i+1; j          {
            if (student[i].avg < student[j].avg)
             {
                  temp = student[i];
                  student[i] = student[j];
                  student[j] = temp;
             }
          }
      /* Storing ranks */
      for (i=0;i         student[i].rank = i+1;
 
      /* Displaying records of students */
      printf(“\n\n Student records after giving them ranks:\n”);
      printf(“\n”);
      printf(“ NAME REGISTER_NUMBER AVERAGE RANK\n”);
      prin tf(“--------------------------------------------------------------
-----------------\n“);
      for (i=0; i       {
         printf(“% -20s 5 -10s”, student[i].name, student[i].    regno);
         printf(:%10.2f %d \n”, student[i].avg, student[i].rank);
       }
