又学了点指针

Sorry, what I said is wrong !
The mistake happens this line swap(int *pointer1,int *pointer2)
There is short of "int" in the original code .

scanf("%d%d",&a,&b);
我觉得这样写的话输入的局限性小.用","的话用户输入的两个值之间还必须要用,分开..

能说的再详细点吗?我觉得你比我说的还乱. 把我都说迷湖了.
为什么要加void swap(int *pointer1,int *pointer2);
  还有.关于return后要跟什么类型啊?
