AIM
A program to copy one file to another file and convert the lower case characters to upper case characters.
ALGORITHM
1) Start the process
2) Create the input file and out put file.
3) Get the input file name to fname1.
4) Get the output file name to fname2.
5) Open the infile(fanme1)
6) Check if infile.fail()
a) True:
i) Execute error conversion
ii) exit
7) open the outfile(fanme2)
check if outfile.fail()
a) repeat step(6:a)
9) check while [...]

AIM
Write a program to illustrate the write() member function which are usually used for transfer of data blocks to the file.
ALGORITHM
1. Start the process
2. Invoke the class
a. Create two inline member functions .ie, getdata() and dispdata()
i. getdata() for input
ii. dispdata() for display
3. Open the file in fstream mode
4. Write the data in to the file
5. Slose the file
6. Stop the process

AIM
A program to demonstrate how a pure virtual function is defined, declared and invoked from the object of derived class through the pointer of the base class.
ALGORITHM
1. Start the process
2. Invoke the class with pointer
3. Assign ptrgetdata()
a. Get the roll no and name of the student
5. Call the ptr->display()
a. Print the roll no and name
6. Stop the process

AIM
A program to access the member of the derived class objects through an array of members. In this program, both the base class and the derived class member functions are preceded by the keyword
ALGORITHM
1. Start the process
2. Invoke the class with pointer
3. Assign ptr[0]

AIM
Write a program to illustrate the static member function.
ALGORITHM
1. Start the process
2. Invoke the class
i. Set the data member and member function as a static
b. Create two objects t1 and t2
3. Call the function t1.setcode
i. Increment the value of data member count
4. Call the function t1.setcode
i. Increment the value of data member count
5. Call the static member function showcount()
i. Display the value of count
6. Create a [...]
