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...

intans =0;for(inti =0; i < n; ++i) {if(s[i] =='/') {intp = i-1;while(p >=0&& s[p] =='1') {p -=1;}intcnt1 = i-1-p;p = i+1;// 错误示范:s[p] == '2' && p < nwhile(p < n && s[p] =='2') {p +=1;}intcnt2 = p - (i+1); ...
Alternatively, we can declare a C-style array to store and return multiple values from the function. This method provides a more straightforward interface for working with a larger amount of values. It’s more efficient to declare an array in the caller function and pass its address to the ...
A pointer to an array points to the first of the array elements and has its type; thus, the return type of the function is a pointer to type char.You need not declare functions with int return type before you call them, although prototypes are recommended so that correct type checking ...
