Re: [suse-programming-e] working with bits

Raúl Gutiérrez Segalés wrote: Hi,

I am trying to do a NOT operation but it doesnt seem to work well:

unsigned int i=8;

printf("%d \n", ~i);

This is suppose to print 247 but I get -9

sure? With "unsigned char" I would expect 247 but not with "unsigned int".

Any ideas of what am I doing wrong ?

Try "%u" instead of "%d" in your printf statement. Michael
