This article will introduce how to return a 2D array from a function in C++. Use Pointer Notation to Return 2D Array From Function in C++ Return by the pointer is the preferred method for larger objects rather than returning them by value. Since the 2D array can get quite big, it’s be...
In this article, we will see how to return array from function in C++. It is not possible to directly return an array to a function call and it can be done by using pointers. If you declare a function with a pointer return type that returns the address of the C-type array, then ...
Return array from a function Objective-C编程语言不允许将整个数组作为参数返回给函数。 但是,您可以通过指定不带索引的数组名称来返回指向数组的指针。 您将在下一章学习指针,这样您就可以跳过本章,直到您理解Objective-C中的指针概念。 如果要从函数返回一维数组,则必须声明一个返回指针的函数,如下例所示 - int ...

you can return a pointer, in which case you need to ensure the array behind it is still alive (not destroyed when the function ended!) or you can return a struct that holds an array, and there are other tricky ways to get the job done. Don't let the syntax hold you back, C can...

C在傳遞資料進function時,就只有兩招,一招是call by value,一招是call by address(實際上也是一種call by value,只是它copy的是value的address,而不是value本身),一些較小型的型別如int、double,我們會使用call by value配合return,當然使用call by address亦可;而一些較大的型別,如string、array、struct,我們會...

C\C++中的return不带参数 return ;其实就是void类型函数的返回。你不写也可以,但是有这样一个情况需要考虑void function(){ if(xxx) return ; aaa; bbb; cccc;}上面有aaa,bbb,ccc三行代码。如果你需要判断某某某条件不满足的时候,函数直接返回,那么就需要使用到return ;了。换句话说,这个语句可以使函数提前...
