7/19/16 update: setup cppcheck v1_58
does not work:
ERROR: Product 'cppcheck' (with qualifiers ''), has no v1_58 version (or may not exist)

so tried: ups list -aK+ cppcheck
and the list is empty.

Checking your code for non-compile time errors with cppcheck.

cppcheck is a very handy tool available for checking your code that gcc can't catch like array out of bound error and can also be used for optimization. The tool is documented here.

It is setup at Fermilab using ups. To do so you can

setup cppcheck v1_58

You then test the code in directory MyDir by doing

cppcheck --enable=style MyDir

It will print out details for optimizing or fixing your code.
