Because the layer of abstraction is slim and the overhead is low, C enables programmers to build productive implementations of algorithms and details structures, beneficial for computationally powerful systems.

Except if the intent of some code is stated (e.g., in names or reviews), it really is unachievable to inform whether the code does what it is actually imagined to do.

More multi-byte encoded people may be Utilized in string literals, but they're not fully portable.
