指標加減的例題程式碼：

#include<stdio.h>

int main(void)
{
	 int a[5] = {1,2,3,4,5} ;
	 int *ptr = (int *)(&a+1) ;
	 
	 printf("%d\n",*(a+1)) ;
	 printf("%d\n",*(ptr-1)) ;
	 
	 return 0 ;
	 
}

#include<iostream>
using namespace std ;

int main(void)
{
	 char str1[] = "abc" ;
	 char str2[] = "abc" ;
	 const char str3[] = "abc" ;
	 const char str4[] = "abc" ;
	 const char* str5 = "abc" ;
	 const char* str6 = "abc" ;
	 char * str7 = "abc" ;
	 char * str8 = "abc" ;
	
	 cout<<(str1 == str2)<<endl ;
	 cout<<(str3 == str4)<<endl ;
	 cout<<(str5 == str6)<<endl ;
	 cout<<(str6 == str7)<<endl ;
	 cout<<(str7 == str8)<<endl ;
	 
	 return 0 ;
	 
}
