If the new size is smaller than the old size, then the array is truncated and all unused memory is released. Use this function to set the size of your array before you begin using the array. If you do not useSetSize, adding elements to your array causes it to be frequently reallocated...
在C语言中,数组作为函数参数时将退化为指针。 #include<stdio.h>//Sizeof on array function parameter will return size of 'int *' instead of 'int []'intsizeofArray(intarray[]){returnsizeof(array);}intmain(intargc,constchar*argv[]){// insert code here...intdata1[]={1,2,3,4,5};si...

中文含义:sizeof使用数组作为参数时会返回int*大小(指针的字节数),即使用sizeof测试数组类型的参数大小时得到的并不是整个数组的字节数,而是指针的字节数(数组被退化为指针使用sizeof) 原因是数组作为参数传给函数时,是传给数组首个元素的地址,而不是传给整个的数组空间,因此 ...
UnmanagedType.SafeArray means that the actual native array type at the function boundary is a SAFEARRAY. The VarEnum.VT_UI1 value assigned to SafeArraySubType specifies that the type of the data stored in the safe array is BYTE (which is an unsigned integer of size exactly of one byte...
您可以在 C++/CX 程式中任意使用標準 C-Style 陣列或std::array(雖然std::vector通常是比較好的選擇),但若是在中繼資料中所發行的任何 API 中,您必須根據 C-Style 陣列或向量的用途,將其轉換為Platform::Array或Platform::WriteOnlyArray類型。Platform::Array類型的效率及功能都不如std::vector,因此一般來說,...
