What is the exact different between QA and QC?

Answer Posted / haroon ali

Exact difference is....
Quality control is an iterative method of comparing the
product to requirements and taking action if there is a
difference.
Quality assurance supports quality control by providing
evidence and confidence of the ability of the software
process to produce a software product that meets specified
requirements.
Also we can say...
Quality control activities are focused on the deliverable
itself.
Quality assurance activities are focused on the process
used to create the deliverable.
