No this is not wrong, it is completly dependent on the platform and compiler
you are working with, for portablity reasons you should assume a 16-bit int. 
I should have said to specify a "short int foobar", however in the K&R 
2nd ed C book, it specifically says an "int" is either 16 or 32 bits 
depending on the host machine, page 36 I believe.
