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
