第一,针对函数作用域(Function Scope): A variable “set” or “unset” binds in this scope and is visible for the current function and any nested calls within it, but not after the function returns.---from cmake languag

注意,这种情况下使用const定义常量可能更好,如const int MAX_TIME = 1000;。因为const常量有数据类型,而宏常量没有数据类型。编译器可以对前者进行类型安全检查,而对后者只进行简单的字符文本替换,没有类型安全检查,并且在字符替换时可能会产生意料不到的错误。 【例2】反例: 1 #define pint (int*) 2 pint pa...

The optional S-function method mdlInitializeConditions initializes the continuous state vector. The #define statement before this method is required for the Simulink engine to call this function. In the example below, ssGetContStates obtains a pointer to the continuous state vector. The for loop th...
