Of course, because the hard disk is not actually written,So you can create 100G of such files on a hard drive with a capacity of only 10G.4. Replace the sa

I have been fascinated by JSON these days, and even some XML work in the project has been handed over to JSON. JSON is much more convenient than XML, but there is a problem.

In C, the primary purpose of a 0-length array is to be used as the last member of the structure body, and then to use it to access a segment of memory (usually dynamically allocated memory) after this structure object. Because of its nonstandard nature, try to avoid using 0-leng
