 0123456789 9876543210
 0123456789 9876543210
 0123456789 9876543210
 0123456789 9876543210

• Program 3:
In this program, your program reads a text file and output erases all non-alphabetical
characters and for all words larger than 10 characters, converts them to uppercase and
prints on the screen (use: cout)

1_counter.exe compiled successfully.
1_counter.exe got correct output.
Exit code: 0
2_pattern.exe compiled successfully.
2_pattern.exe got correct output.
Exit code: 0
3_convert.exe compiled successfully.
3_convert.exe got correct output.
Exit code: 1
Execution of your program
>./a.out input
will generate the following output on the screen
COUNTEREXE
