Answer to Question #175087 in C++ for osama

Question

Write a program in C++ which stores and displays the details of 3 students in arrays. Your program should:  Take the following inputs from the user: Name, department, year of enrolment, discipline, age, gender, gpa. Choose appropriate data types for the arrays to store each type of input information.  Once the details of the student have been entered in the different arrays, display a summary of the details for the student.  In the next step, calculate the average gpa of the three students and display it.  In the final step, swap the discipline and gpa of Student1 and Student2.  Display the final updated summary details for each student.
