class B
{
public :
int a,b;
};
void A::read()
{
cout<<"welcome";
}
main()
{
A x;
B y;
y.read();
}
In the above program......,
as B is a friend of A B can have access to all members,i
cant access y.read .
could you please tell me the reason and what would i code
to execute this program?

Question 1: Implement a base class Appointment and derived classes Onetime, Daily, Weekly, and Monthly. An appointment has a description (for example, “see the dentist”) and a date and time. Write a virtual function occurs_on(int year, int month, int day) that checks whether the appointment occurs on that date. For example, for a monthly appointment, you must check whether the day of the month matches. Then fill a vector of Appointment* with a mixture of appointments. Have the user enter a date and print out all appointments that happen on that date. *This Should Be Done IN C++
1. Write a program that performs the following. The user inputs a number and then enters a series of numbers from 1 to that number. Your program should determine which number (or numbers) is missing or duplicated in the series, if any. For example, if the user entered 5 as the initial number and then entered the following sequences, the results should be as shown. Input Sequence Output ---------------------- --------------- 1 2 3 4 5 Nothing bad However, if 7 were the high number, the user would see the results on the right for the following number entries: Input Sequence Output ---------------------- --------------- 1 3 2 4 5 Missing 6 Missing 7 And if 10 were the high number and the user entered the numbers shown on the left, note the list of missing and duplicate numbers: Input Sequence Output ---------------------- --------------- 1 2 4 7 4 4 5 10 8 2 6 Duplicate 2 ( 2 times) Missing 3 Duplicate 4 ( 3 times ) Missing 9
write a c program, using for loop, that accepts and odds two numbers. The output must be the sum and the addens. This should be repeated 5 times while the first number is decremented by one and the second number is incremented by 1.
