Here if first checks the condition either the a is greater than b if yes then it will print a suppose if a is not greater than b then it will be print b because we specify the b in the else statement. 2) if-elseif The if-elseif is similar to the if-else but here the first ...
Never Nester, Goto, RAII, and Defer Coding when you are using an OS or library that requires a series of calls that build on each other to get the final result requires a set of checks to make sure each stage is successful. If some of the stages also require it partner call to free...
the same loop or anything like that. Thanks for the suggestions, I'll have a look at that, not familiar with the api at all really (literally started learning c++ a week ago). I do find the documentation a little confusing to follow tbh... Is cppreference the goto site for c++ docs...

将inline 函数体复制到 inline 函数调用点处; 为所用 inline 函数中的局部变量分配内存空间; 将inline 函数的的输入参数和返回值映射到调用方法的局部变量空间中; 如果inline 函数有多个返回点,将其转变为 inline 函数代码块末尾的分支(使用 GOTO)。优缺点优点...
In this post I would like to share my observation on where using noexcept really adds value. It is less often than what one might expect, and it does not have that much to do with throwing or not throwing exceptions. The conclusion surprises me a bit, an
