C++ performs “implicit conversions” between different types, such as silently converting char to int or int to char. “Implicit conversions” allow us to successfully provide a short or int to a function that requires a double.The above “implicit conversions” are provided by the language, and we cannot refuse them. However, C++ allows us to provide … Read more
Previously, I really took a lot of detours while learning Python. 😠I blindly watched online courses 📺 and took a ton of notes 📒, but when it came to coding, my mind went blank… I knew the syntax, I had filled three notebooks, and felt like I understood everything, but when I first tried … Read more
Many libraries and functions we use require us to pass raw resources instead of a resource management class object. Therefore, it is essential to design methods in resource management classes to access raw resources. Currently, there are two mainstream methods: 1. Explicit Conversion (Recommended) This method involves designing a function that returns the internal raw … Read more
For those just starting with C language, do you often encounter these confusions: Your program compiles without errors, but suddenly crashes at runtime? You want to change the input every time the program runs, but can only modify the code and recompile? Today, we will break down two core concepts in C language that are … Read more
In some problems involving “cycles” (such as looping playback or polling tasks), it is necessary to iterate over a given list multiple times. Here, iteration means going from the first element to the last, and then starting again from the first element, repeating this process. Let’s start with some music~ The following example will cyclically … Read more

We encourage clear philosophical thinking in programming rather than rigid rules. I do not expect you to agree with everything, as they are merely opinions that change over time. However, if I had not written them down until now, these opinions, based on much experience, have long accumulated in my mind. Therefore, I hope these … Read more
