4.9.3 在switch语句中应有default语句。 4.9.4 不应使用空switch语句。 4.9.5 switch语句中不应只包含default语句。 4.9.6 所有非空的switch case子句都应以break 语句结束。 4.9.7 switch控制表达式不应是一个常量或逻辑表达式。 逻辑表达式只有真和假两种情况,当需要对逻辑表达式判别时,应使用if …… else语句...
在本章中,我们将完全用C语言,实现面向对象中最重要的几个概念,分别是继承,覆盖。我们先看实现后的调用: int main (int argc, char ** argv) { void * p; while (* ++ argv) { switch (** argv) { case &#…

类似于C的switch语句: select case (变量) case (数值1) ! 比如case (1:5) 代表1<=变量<=5会执行该模块 ... ! case (1,3,5) 代表变量等于1或3或5会执行该模块 case (数值2) ! 括号中数值只能是integer, character或logical型常量,不能real型... case default ... end select 3-4、PAUSE, CO...
switch(condition): case A: break case b: break case c: break default: break 之前的数组规约也有一个判断条件,if(n < N){},这的话也存在分支,不满足条件的线程束内的线程会闲置起来。写CUDA的时候要尽量避免分支发散。否则性能会变差。 线程束内的线程同步函数 ...
