Using the p, n, and % conversion specifiers
#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
28 characters were printed
