Question

I need help implementing Student(const char initId [], double gpa) without using pointers. I don't know how to initialize this with the passed in gpa value.

Using C++, implement the member function specified in student.h in the implementation file, student.cpp

Student(const char initId[], double gpa)

{

}

This function will initialize a newly created student object with the passed in value.

Helpful info:

From student.h

class Student
   {
   public:
          Student(const char initId[], double gpa);
          bool isLessThanByID(const Student& aStudent) const;
          bool qualifyForHonor(double minGpaForHonor) const;
          void print()const;
private:
          const static int MAX_CHAR = 100;
          char    id[MAX_CHAR];
          double gpa;
};

From main.cpp: (to test student.cpp)      

#include "student.h"

int main()
{
         Student s1("G10", 3.9);
         Student s2("G20", 3.5);

         s1.print();
         s2.print();
         return 0;
}

#include<iostream>
using namespace std;
class Student
{
public:
Student(const char initId[], double gpa);
bool isLessThanByID(const Student& aStudent) const;
bool qualifyForHonor(double minGpaForHonor) const;
void print()const;
private:
const static int MAX_CHAR = 100;
char id[MAX_CHAR];
double gpa;
};

//implementing constructor
Student::Student(const char initId[], double gpa)
{
   this->gpa = gpa;//setting gpa
   int i;
   for(i=0;initId[i]!='\0';i++)
   id[i]=initId[i];//setting ID
   id[i]='\0';
}
//method to print
void Student::print() const
{
   cout<<"ID: "<<id<<"\nGpa: "<<gpa<<endl;
}
int main()
{
   Student s1("G10", 3.9);
Student s2("G20", 3.5);

s1.print();
s2.print();
   return 0;
}

output:

ID: G10
Gpa: 3.9
ID: G20
Gpa: 3.5
