Question

Write a C++ program to make a structure of a student consisting of integer age, char name and

structure roll number that further divides into department, session, registration number and

degree. Set and display all the values from main function and display the record on screen to

present the access of structure within structure. You have to by access structure using pointer

type variable of structure.

Answer 1

#include <iostream>

struct RollNumber
{
	const char* department;
	const char* session;
	int registrationNumber;
	const char* degree;
};

struct Student
{
	const char* name;
	int age;
	RollNumber* rollNumber;
};

int main()
{
	RollNumber* rollNumber = new RollNumber;
	rollNumber->department = "Mathematics";
	rollNumber->session = "Spring 2022";
	rollNumber->registrationNumber = 284735;
	rollNumber->degree = "Bachelor";
	Student* student = new Student;
	student->age = 22;
	student->name = "John Wales";
	student->rollNumber = rollNumber;
	std::cout << "Name: " << student->name << std::endl;
	std::cout << "Age: " << student->age << std::endl;
	std::cout << "Roll number: " << std::endl;
	std::cout << "* Department: " << student->rollNumber->department << std::endl;
	std::cout << "* Session: " << student->rollNumber->session << std::endl;
	std::cout << "* Registration number: " << student->rollNumber->registrationNumber << std::endl;
	std::cout << "* Degree: " << student->rollNumber->degree << std::endl;
	delete student;
	delete rollNumber;
	return 0;
