GCEM: A Powerful C++ Compile-Time Math Library GCEM (Generalized Constant Expression Math) is a C++ based compile-time mathematical computation library. It utilizes the <span>constexpr</span> feature of C++11 to perform mathematical operations during the code compilation phase, significantly enhancing program execution efficiency. Next, let’s delve into this amazing library. The Charm of Compile-Time Computation The core … Read more
When writing C++ programs, we sometimes need to verify whether certain conditions are met, such as whether the array size is acceptable or whether template parameters are valid. If these issues are discovered at runtime, they can cause the program to crash unexpectedly. Static assertions (static_assert) are a compile-time tool provided by C++, which can … Read more
Have you ever thought about how some simple syntax rules in C can lead to clever methods? For example, the length of an array in C cannot be negative; of course, it makes no sense for an array length to be negative. For instance, int arr[1]; is correct, while int arr[-1]; is incorrect. This rule … Read more
