这个程序为什么不对!(求救!!!!!!!!
#include <iostream>
using namespace std;
int main()
{
void swap(int *p1, int *p2)
int *pointer_1,*pointer_2,a,b;
cin> > a> > b;
pointer_1=&a;
pointer_2=&b;
if(a <b) swap(pointer_1,pointer_2);
cout < < "max= " < <a < < "min= " < <b < <endl;
return 0;
}
void swap(int *p1,int *p2)
{int temp;
temp=*p1;
*p1=*p2;
*p2=temp;
}
运行结果是:

[解决办法]
include <iostream>
using namespace std;
void swap(int *p1, int *p2);
int main()

return 0;
}
void swap(int *p1,int *p2)
{int temp;
temp=*p1;
