下一個範例顯示如何從 C-Style 陣列建構 Platform::Array,並從公用方法中傳回它。C++ 複製 Array<int>^ GetNums() { int nums[] = {0,1,2,3,4}; //Use nums internally... // Convert to Platform::Array and return to caller. return ref new Array<int>(nums, 5); } ...
myArray.Add(30);intn = myArray.GetSize();//获取此数组中的元素数n = myArray.GetUpperBound();//返回最大的有效索引 CString str; CArray<int,int>myArray; myArray.Add(1); myArray.Add(3); myArray.InsertAt(1,2);//在索引为 1 的位置插入元素 2for(inti =0; i < myArray.GetSize();...
int mark[5] = {19, 10, 8, 17, 9}; C initialize array can be done using this formula: int mark[] = {19, 10, 8, 17, 9}; Here, the size is left unspecified. However, because we initialize it with 5 elements, the compiler is aware that it has a size of 5. ...

array不是C语言中的关键字,只是编程人员自定义的一个变量或数组等,通常用来定义数组,是数组的英文。...
3) 访问数组元素时,下标的取值范围为 0 ≤ index < length,过大或过小都会越界,导致数组溢出,发生不可预测的情况。2.数组内存是连续的 数组是一个整体,它的内存是连续的;也就是说,数组元素之间是相互挨着的,彼此之间没有一点点缝隙。下图演示了int a[4];在内存中的存储情形:「数组内存是连续的」这...
