why the -1 in the positive limit of a range of a type?
Hello i read in some book that the range of:
int is: between (231-1) and (-231)
short is: between (215-1) and (-215)
long long is: between (263-1) and (-263)
...etc
my question is why the (-1) in the positive limit? and why the is no (-1) in the negative one?.
