Chapter 6 branch statements and logical operators Forced type conversion in test conditions As long as these true and false judgments are used, the system will forcibly convert them to the bool type. Therefore, the system will automatically complete the conversion of the general value type, however, for our custom class type or structure, we need to overload the bool forced type conversion operator to implement this function. Therefore, it is also fea

Chapter 8 function Exploration Inline function Selection If the Compilation Time of the function Execution Code is longer than that of the function calling mechanism, the time saved will be only a small part of the whole process. If the code execution time is short, the inline call can save most of the time for non-inline calls. In short, inline is used to define short functions that are frequently called, for example, calling a function in a loop. In
