这是《C／C++程序员实用大全》上面的源码

				#include 
				
				class c {
				 public:
				 	int j;
				   c(void) {j=10;}
				 };
				
				void PrintInt(const c* Object)
				 {
				 	c* New = Object;
				   New->j +=5;
				   printf("%d\n", New->j);
				 }
				
				void main(void)
				 {
				 	const c Sample;
				
				   PrintInt(&Sample);
				 }
