Write a C++ program to read and write the student data by using structure.

#include <iostream.h> 
 #include<conio.h> 
 #include <string.h> 
 struct student 
 { 
        char firstName[20]; 
        char lastName[20]; 
        char SSN[10]; 
        float gpa; 
  }; 
              void main() 
          { 
                clrscr(); 
                 struct student st1 ; 
                 strcpy(st1.firstName, "Dinesh"); 
                 strcpy(st1.lastName, "Thakur"); 
                 strcpy(st1.SSN, "228378" ); 
                 st1.gpa = 22009.20; 
                 cout<<"First Name: "<< st1.firstName<<endl;              
                 cout<<"Last Name:"<<st1.lastName<<endl; 
                 cout<<"SNN : "<<st1.SSN<<endl; 
                 cout<<"GPA: "<<st1.gpa<<endl; 
                 getch();
