#include <stdio.h>

int main()
{ 
   int *ptr;
   int x = 12345;
   int y;        
   
   ptr = &x;     
   printf( "The value of ptr is %p\n", ptr );
   printf( "The address of x is %p\n\n", &x );

   printf( "Total characters printed on this line:%n", &y );
   printf( " %d\n\n", y );

   y = printf( "This line has 28 characters\n" );
   printf( "%d characters were printed\n\n", y );
   
   printf( "Printing a %% in a format control string\n" );

   return 0;

}

The value of ptr is 9a378
The address of x is 9a378

Total characters printed on this line: 38

This line has 28 characters
