UDF源代码如下:/***UDF for initializing flow field variables***/#include "udf.h"DEFINE_INIT(my_init_func,d){ cell_t c; Thread *t; real xc[ND_ND]; /* loop over all cell threads in the domain */ thread_loop_c(t,d) { /* loop over all cells */ begin_c_loop_all(c,t) { ...
#define 则是宏定义,发生在预处理阶段,也就是编译之前,它只进行简单而机械的字符串替换,而不进行任何检查。 例如:typedef 会做相应的类型检查 1 2 3 4 5 6 7 typedef unsigned int UINT; void func() { UINT value = "abc"; // error C2440: 'initializing' : cannot convert from 'const char [4...
error C2440: 'initializing' : cannot convert from 'int' to 'some_big_cities' 可见,不能直接地把一个整型赋值给一个枚举变量,因为枚举和整型是不同类型的,除非显式转换。关于枚举与整型的关系,后面再讲。 除了初始化,枚举变量也有赋值运算: some_big_cities wh; wh = Guangzhou; wh = Shanghai; 或者 ...
{ UINT value = "abc"; // error C2440: 'initializing' : cannot convert from 'const char [4]' to 'UINT' cout << value << endl; } 【例1.2】#define不做类型检查: // #define用法例子: #define f(x) x*x int main() { int a=6, b=2, c; c=f(a) / f(b); printf("%d\n"...
