2. For the C++ language:
a. Make a list of the different ways to
preform the file operations Create, Open, Close, Read, and Write. Why
is there more than one way to do each operation?
b. How would you use fseek to
find the current position in a file?
3. A couple of years ago a company we know bought a new Cobol compiler.
One difference between the new compiler and the old one was that the
new complier did not automatically close files when execution of a
program terminated, whereas the old compiler did. What sorts of
problems did this cause when some of the old software was executed
after having been recompiled with the new compiler?
6. Look up the Unix command wc. Execute
the following in a Unix environment, and explain whey it gives the
number of files in a directory.
ls | wc -w
