Answer 1

// C code

#include<stdio.h>
#include<conio.h>
#include<stdlib.h>
typedef struct {
   char first[20];
   char last[20];
   float gpa;
   int score;

} student;

int main()
{
   student* ptr = NULL;
   FILE* fptr;
   //Open file
   fptr = fopen("studentInfo.txt", "r");
   //If file not found...
   if (fptr == NULL)
   {
       printf("cannot open file \n");
       return -1;
   }
   // ask a user to enter the number of students, num
   printf("Enter number of students: ");
   int n;
   scanf("%d", &n);
   //create dynamic array of students...
   ptr = (student*)malloc(n * sizeof *ptr);
   int count = 0;
   //Read students from file
       for (int i = 0; i < n; i++)
       {
           fscanf(fptr, "%s", ptr[count].first);
           fscanf(fptr, "%s", ptr[count].last);

           fscanf(fptr, "%d", &ptr[count].score);          
           count++;
       }

   //first name //last name //student gpa //student score
       //Display students.......
       for (int i = 0; i < n; i++)
       {
           printf("Name: %s %s, GPA = %.2f, Score = %d\n", ptr[i].first, ptr[i].last, ptr[i].gpa, ptr[i].score);
       }

}

//studentInfo.txt

//Output

//If you need any help regarding this solution........ please leave a comment..... thanks
