[LCP]sign problem

[Arindam Chatterjee]

actually the same value gets stored when you are storing negative number
in a signed or unsigned
variable.  do
  unsigned int x = -9;
  int y = -9;
  printf("x = %x   y = %x ", x, y);

How are u printing ? If u use printf("%d", ...) to print the unsigned
number then it will show u the negative
number, bcoz printf is changing it to signed value. You have to print
using printf("%u") to get what u
want.
