Last year, I specifically introduced the extremely rare C++ syntax <span>……</span> in the article “What does the …… mean in C++?” which is actually an abbreviated syntax for <span>…, …</span>. The following three forms are completely equivalent: template<class… Args> void f(Args……) {} template<class… Args> void f(Args… …) {} template<class… Args> void f(Args…, …) {} The … Read more
JSON is a lightweight data interchange format, while C++ is a powerful programming language. However, the combination of C++ and JSON is not so natural. Fortunately, the jsonifier library has emerged, acting as a bridge that allows C++ and JSON to communicate easily. jsonifier enables C++ programs to conveniently handle JSON data, whether it is … Read more
