Certainly! Here's an example that demonstrates the usage of pointers to structures in C++:

cppCopy code

#include <iostream> #include <string> struct Student {    std::string name;    int rollNumber;    char grade; }; int main() {    Student student; // Declare a structure variable    Student* ptrStudent = nullptr; // Declare a pointer to Student and initialize it with nullptr    // Assign the address of student to the pointer    ptrStudent = &student;    // Access and modify structure members using the pointer    ptrStudent->name = "John Doe";    ptrStudent->rollNumber = 101;    ptrStudent->grade = 'A';    // Access structure members using the pointer and print them    std::cout << "Student Name: " << ptrStudent->name << std::endl;    std::cout << "Roll Number: " << ptrStudent->rollNumber << std::endl;    std::cout << "Grade: " << ptrStudent->grade << std::endl;    return 0; }

In this example, we define a structure called Student with three members: name (string), rollNumber (integer), and grade (character).

Inside the main function, we declare a structure variable student. Then, we declare a pointer to a Student structure named ptrStudent and initialize it with nullptr to ensure it doesn't hold any random memory address.

Next, we assign the address of the student variable to the ptrStudent using the address-of operator &.

To access and modify the structure members through the pointer, we use the arrow operator ->. For example, ptrStudent->name accesses the name member of the student structure.

Finally, we print the values of the structure members using the pointer.

You can modify and expand this code to practice other operations with pointers to structures, such as dynamic memory allocation, passing pointers to functions, and more.
