Why is object oriented programming so hard?
hi, this is raju,iam studying b.tech 2nd year,iam want know about group1 and group2 details, and we can studying without going to any instutions? please help me.
Give an example where we have to specifically use C programming language and C++ programming language cannot be used?
Why do we use inheritance?
what type of questions
IS IT NECESSARY TO INITIALIZE VARIABLE? WHAT IF THE INSTANCE VARIABLE IS DECLARED final ? IS IT NECESSARY TO INITIALIZE THE final VARIABLE AT THE TIME OF THEIR DECLARATION?
Explain the advantages of inheritance.
Write a program to compute for numeric grades for a course. The course records are in a file that will serve as the input file. The input file is in exactly the following format: Each line contains a student's first name, then one space, then ten quiz scores all on one line. The quiz scores are in whole number and are separated by one space. Your program will take it input from this file and sends it output to a second file. The data in the output file will be exactly the same as the data in the input file except that there will be one additional number (of type double) at the end of each line. This number will be the average of the student's ten quiz scores. Use at least one function that has file streams as all or some of its arguments.
What is encapsulation in oop?

for(j=1;k-i;k+=j<10?4:3)

cout< What is abstraction in oop? Objective
The objective of this problem is to test the understanding
of Object-Oriented Programming (OOP) concepts, in
particular, on encapsulation.
Problem Description
Create a program for managing customer’s bank accounts.
A bank customer can do the following operations:
1. Create a new bank account with an initial balance.
2. Deposit money into his/her account.
3. Withdraw money from his/her account.
For this operation, you need to output “Transaction
successful” if the intended amount of money can be
withdrawn, otherwise output “Transaction unsuccessful” and
no money will be withdrawn from his/her account.
Input
The input contains several operations and is terminated by
“0”. The operations will be “Create name amount”,
“Deposit name amount”, or “Withdraw name amount”, where name
is the customer’s name and amount is an
integer indicating the amount of money. There will be at
most 100 bank accounts and they are all created on
the first month when the bank is opening. You may assume
that all account holders have unique names and the
names consist of only a single word.
Output
The output contains the transaction result of withdrawal
operations and the final balance of all customers after
some withdrawal and deposit operations (same order as the
input).
Sample Input
Create Billy 2500
Create Charlie 1000
Create John 100
Withdraw Charlie 500
Deposit John 899
Withdraw Charlie 1000
