C语言基础：指针使用演示代码

#include <stdio.h>
int main(void)
 {
   int counter = 10;
   int *iptr;          // Declare pointer value
   iptr =     // Assign the address
   printf("Addres in iptr %x Value at *iptr %d\n", iptr, *iptr); 
   
   *iptr = 25;         // Change the value in memory
   printf("Value of counter %d\n", counter);
return 1;
 }
