I want to use the data members to store the info on the file and then read and display them through these two member functions in the class but i can't think of syntax. i made global variables but didn't use the data members in the class. i stored and read data by global variables but couldn't do it by data members of the class.
#include<iostream.h>
#include<fstream.h>
/* Making Global Pointer Variables to use anywhere in the program*/
const char* ID = "VUID = "mc123456789";
const char* camID = "Campus ID = "PMMK08";
const char* stdntnme = "Name = "xxxx xxxx xxxx";
const char* Fthrnme = "Father's Name = "xxxx xxxx xxxx";
ofstream re;
class studentinfo
{
private:/*Creating Private Data Members */
char* VUID;
char* campusID;
char* Studentname;
char* Fathername;
public:
