Question

Consider the Tollowing class declaration: class student record public: int age; string name; double gpa; }: Implement a void function that initiatizes a dynamic array of student records with the data stored in the file "university body.txt". The function has three formal parameters: the dynamic array "S db, the count, and the capacity. Open and close an ifstream inside the function. Remember, you must allocate memory for the initial size of the dynamic array using "new" inside this function. If the array becomes full, print a message stating so, close the file, and exit the function.Consider the following declarations to help you write (code) this function: Declarations: student_record "S_db; 25; //this is the capacity of the dyamic array S_db. const int CAPACITY int count -0; /holds the number of records being used in the dynamic array S_db.

Code

#include<iostream>
#include<string>
#include<fstream>
using namespace std;

class student_record
{
public:
   int age;
   string name;
   double gpa;
};

void readRecords(student_record *S_db,int capacity,int *count)
{
  
   ifstream inFIle;
   int i=0;
   inFIle.open("university_body.txt");
   if(!inFIle)
   {
       cout<<"Error in opening file.File not found."<<endl;
       return;
   }
   while(inFIle>>S_db[i].name>>S_db[i].age>>S_db[i].gpa)
   {
       if(i==capacity)
       {
           cout<<"Array is full. No room for new reords";
           return;
       }
       i++;
       *count=i;
   }
}

int main()
{
   student_record *S_db;
   const int CAPACITY=25;
   int count=0;
   S_db=new student_record[CAPACITY];
   readRecords(S_db,CAPACITY,&count);
   cout<<"Records read from the file: "<<endl;
   cout<<"--------------------------------------------"<<endl;
   for(int i=0;i<count;i++)
   {
       cout<<"Name: "<<S_db[i].name<<endl<<"Age: "<<S_db[i].age<<endl<<"GPA: "<<S_db[i].name<<endl<<endl;
   }
}
