Code blocks allow many algorithms to be implemented with the following parameters :
clarity, elegance, efficiency
A code block is a group of statements enclosed in braces that is treated as a single logical unit.
Grouping statements this way lets an algorithm be written with greater clarity, elegance and efficiency, since related statements stay together and control statements can act on the whole group.
Execution and performance are not the qualities usually attributed to code blocks themselves.
Hence, clarity, elegance, efficiency.
