File.fifty three: Stay clear of capturing by reference in lambdas that could be utilised nonlocally, such as returned, stored around the heap, or handed to a different thread
In conditions in which code need to be compilable by both standard-conforming or K&R C-primarily based compilers, the __STDC__ macro can be utilized to split the code into Conventional and K&R sections to circumvent the use over a K&R C-based mostly compiler of options obtainable only in Common C.
