Dynamic Code Analysis

[suneelkv]

Hi All,

I'm new to this forum and even new to C++ development.
I'm looking for some good dynamic code analyis tools.
Presently I was asked to prepare a tool comparison report for
1) IBM Rational Purify Plus
2) Valgrind
3) Parasoft Insure++

Can somebody guide me which is the best tool out of the above.
I want to evaluate one of them and confirm the same.
Please let me know the pre-coditions/assumptions which should be carried out to perform the above task?

Regards,
Suneel
