C语言用函数改变指针指向 #include <stdio.h> void SwapPointer(int **,int **); void Swap(int *a,int *b); void SwapP(int *a,int *b); int main(int argc, char *argv[]) { int a=1,b=2; int *a1=&a,*b1=&b; printf("原值 a:%d b:%d\n",a,b); printf("原值 a1:%d b1:...

就这段代码来说,就是形参x复制了a的值变成5,形参y复制了b的值变成8,然后在swap函数中进行交换,使得x=8,y=5,但实际上a和b的值并没有被交换,这也就是为什么这段代码并没有实现交换的原因。 那么怎么解决呢? 先前我们说了C语言中整型变量的形式参数传递的是值而不是地址,那么现在我们就让它传递地址,直接交...

Method for using atomic compare-and-swap operations during forwarding-pointer installationA multiprocessor, multi-program, stop-the-world garbage collection program is described. The system initially over-partitions the root sources, and then iteratively employs static and dynamic work balancing. Garbage ...
