Hi,

Maybe I have made a very grave mistake, but I just can't yet understand
why the code attached below produced the following output:

first:      cc22       55258
second:     d7da       55258
third:      ffff       65535

Why are the first two numbers, which are different hexadecimals,
printed out as the same decimal number?

Thanks for your kind help in advance.

M. K. Shen

#include <stdio.h>

int main()
{ unsigned long int g;

   g=0xcc22; printf("first:  %8x  %10lu\n",g,g);

   g=0xd7da; printf("second: %8x  %10lu\n",g,g);

   g=0xffff; printf("third:  %8x  %10lu\n",g,g);

   return(0);
}
