Write a program to take input for n book records from user and write those book records in a file named: ”record”, whose price is less than INR 500 . Program should also perform random access in the file, after taking input for a particular record number to read and it should also perform random record overwriting after taking input of new record and the record number to overwrite. After overwriting record, display all records on the screen. [Attributes of book: Book_id, Book_price, Book_name, Book_author_name]
Write a program to perform class to basic conversion [such as : class is : Triangle with data members base and height (float), and basic type is float(area of triangle)].
Write a program to overload operators in the same program by writing suitable operator friend function for following expression.
O7=((O1>=O2)+(O3&&O4) *(O5<O6)) [here O1,O2,O3,O4,O5,O6 and O7 are object of a class ''overloading", and this class is having one integer data member]
Explain the difference between constructor and initializer list.
Create a program using Python for Eduvos based on the above scenario. The program should initially display a welcome message. The program should then do the following: 3.1 Prompt the user to enter the number of students to be captured. 3.2 Handle exceptions to ensure that the user enters a number. 3.3 Prompt the user to enter the student’s name, exam 1 and exam 2 marks. 3.4 Calculate the test average. 3.5 Use tuples to handle records. 3.6 The records should then be written to a file called studentsexammarks.txt. 3.7 The program should display the recorded test marks on the screen.

Write a program that can perform addition with these overloaded methods:
int add(int x, int y) – returns the sum of two integer values
double add(int x, double y) – returns the sum of an integer value and a double value
double add(int x, int y, double z) – returns the sum of two integer values and a double value
Use the methods in the program. (How would you use them?)

Write a program to take input for n number of doctor records and write records of all cardiologists in
a file named: “record1”. Also write records of all those doctors in another file named: “record2” who are
taking salary more than INR 80,000. After writing records in both files, merge their contents in another
file: “finalrecord” and read all records of “finalrecord” file and display on screen. [Attributes of doctor:
doc_id, doc_name, doc_specialization, doc_salary]
. A prime number is a number that is evenly divisible only by itself and 1. For example, the
number 5 is prime because it can be evenly divided only by 1 and 5. The number 6, however,
is not prime because it can be divided evenly by 1, 2, 4, and 6.
Write a method named as Prime, which takes an integer as an argument and returns true if the
argument is a prime number, or false otherwise. Also write main method that displays prime
numbers between 1 to 500
