Algorithm
Step 1: Start the program.
Step 2: Declare the variables.
Step 3: Read the file name.
Step 4: open the file to write the contents.
Step 5: writing the file contents up to reach a particular condition.
Step 6: write the file contents as uppercase.
Step 7: open the file to read the contents.
