The first thing you should see is the TAG Posting Guidelines
http://linuxgazette.net/tag/ask-the-gang.html
in the FAQ section.  There you'll see we don't do people's homework for
them.  How do we know it's homework?  You don't want to do a useful task:
who cares how many braces a C program has?  You choose the tools first and
then the strategy, and you insist on using kludgey tools.  If I really
wanted to count braces, I would write a Python program.

``
#!/usr/bin/env python
"""count-braces.py

Usage: count-braces.py <filename
Print the number of {}() characters in the input file.
"""
import re, sys

braceRx = re.compile( R"[{}()]" )
text = sys.stdin.read()
hits = braceRx.findall(text)
print len(hits)
