Inquiry Intrinsic Function (Generic): Returns the total number of elements in an array, or the extent of an array along a specified dimension.
通常来说获取数组的长度时不要对指针应用sizeof操作符。 现来看看下面这段代码: void clear(int array[]) { for(size_t i = 0; i < sizeof(array) / sizeof(array[0]); i++) { array[i] = 0; } } void dowork(void) { int dis[12]; clear(dis); /*...*/ } clear()使用sizeof(ar...
ArrayTools Size return the size of an Array in each dimension Calling Sequence Parameters Description Examples Calling Sequence Size( M ) Size( M , n ) Parameters M - Array n - positive integer dimension Description The Size(M) function returns an array.
An array aligns the same as the array element. A structure aligns the same as the field with the widest alignment. Options -f or -dalign force alignment of all 8, 16, or 32-byte data onto 8-byte boundaries. Option -dbl_align_all causes all data to be aligned on 8-byte boundaries....
