ALogD("### yield frame 100"); ACoroutineEnd(); } void main() { ACoroutine->StartCoroutine(CRun); } 只要在begin和end之间,使用Yield就可以让出执行流程,然后在返回接着执行。再次强调,需要保存进度的变量,需要使用params保存或是static local变量。那么,让出执行流程,是如何恢复的呢。那是因为所有协程都...
c:=c + x and 1; x:=x shr 1; end; writeln( c and 1 ); end. 但这样的效率并不高,位运算的神奇之处还没有体现出来。 同样是判断二进制中1的个数的奇偶性,下面这段代码就强了。你能看出这个代码的原理吗? var x:longint; begin readln(x); x:=x xor (x shr 1); x:=x xor (x shr...
int j=1; for(int i=2;i<=m;i++){ if(m%i==0&&n%i==0) j=i; } m=j; return m; //直接返回j这个局部变量会出错

① BEGIN…END语句块包含了该程序块的所有处理操作,允许语句块嵌套。 ②在MySQL中单独使用BEGIN…END语句块没有任何意义,只有将其封装在存储过程、存储函数、触发器等存储程序内部才有意义。 2. 注释 1)单行注释 使用“##”符号作为单行语句的注释符,写在需要注释的行或语句单方。

迭代器小结:C++中通过容器对象的begin或end方法来获取到迭代器,其迭代器的含义是一个指针,指向容器中的元素;而java中的迭代器是一个对象,通过容器的iterator()方法得到容器的迭代器,之后通过迭代器对象的方法hasNext()来获取到容器的指向。 3.C语言常用字符串函数 ...
