2、sizeof('a')在C语言中的结果是4,在C++中结果是1,看过某篇文章说C中sizeof侧重于“数”,而C++中sizeof更侧重于“字符”。 3、文章中讲了两个用宏实现sizeof的经典应用 复制代码 代码如下: //适用于非数组 #define _sizeof(T) ((size_t)((T*)0 + 1)) //适用于数组 #define array_sizeof(...
void * memset(void * s,int c,sizeof(s))。 六、建议 由于操作数的字节数在实现时可能出现变化,建议在涉及到操作数字节大小时用ziseof来代替常量计算。 2)SizeOf Pascal的一种内存容量度量函数: 用法: Var a : array[1..10000] of longint; ...
To map a C function argument to an InputOutput scope, define the variable as a pointer in your function. extern void mean_filter(unsigned char* src, unsigned int width, unsigned int height, unsigned int filterSize); Then set the scope to InputOutput in the Port Specification table and as...

这是一个依赖于编译系统的值,一般定义为typedef unsigned int size_t;编译器林林总总,但作为一个规范,都会保证char、signed char和unsigned char的sizeof值为1,毕竟char是编程能用的最小数据类型。 MSDN上的解释为: The sizeof keyword gives the amount of storage, in bytes, associated with avariable or ...
