defer in C++/Objc 写过swift的同学应该都知道defer这个关键字,可以让我们在函数return之前执行指定的代码,这对于有多个提前return而忘记释放资源的函数来说,简直不要太方便了,然而对于swift的前辈Objective-C或C++来说,苹果并没有帮我们定义,因此本文总结一下如何在C++和Objective-C中实现defer。 02 C中的预编译...

Parameter In C++, pointer arguments are used for both scalar data and array data. To use a pointer as an array, MATLAB®needs dimension information to safely convert the array between C++ and MATLAB. Theparameter helps you specify the dimensions for the pointer. Note Pointers representing arra...
