將陣列傳到function時,由於陣列可能很大,若用pass by value的方式傳進function,勢必造成大量copy的動作而降低效能,C語言是靠pointer的方式,將陣列第一個元素的位址以pointer的方式傳進function。 1/* 2(C) OOMusou 2007http://oomusou.cnblogs.com 3 4Filename : ArrayPassToFunctionCStyle.c 5Compiler : Visual...
A pointer that points to nothing is called a Null pointer. Some advantages of Null pointer are: We can initialize a pointer variable when that pointer variable is not assigned any actual memory address. We can pass a null pointer to a function argument when we are not willing to pass any ...

In C, an array is basically a pointer whose value cannot be changed. In fact, when you pass an array as a parameter, the only thing that really gets passed is the memory address of the first element of the array. So you can write something like the following....
Simulink can pass N-D array data to custom code functions in C Caller blocks, and receive data from such blocks. When you do so, you must specify the correct array layout to achieve the intended results. See Default function array layout and Exception by function. For examples of the use...

You can pass an array such asaorbto a function in two different ways. Imagine a functiondumpthat accepts an array of integers as a parameter and prints the contents of the array to stdout. There are two ways to codedump: void dump(int a[],int nia) ...
