unsigned int max value

Copy codeThe Code is as follows: # include Int main (int argc, char * argv []) { Unsigned int max_int = 0-1; Printf ("The max value of unsigned int on 32 machine: % u/n", max_int ); } Copy codeThe Code is as follows: # include Int main (int argc,

Copy Code code as follows: #include int main (int argc, char *argv[]) { unsigned int max_int = 0-1; printf ("The max value of unsigned int on machine:%u/n", max_int); } Copy Code code as follows: #include

Some people have mentioned the difference between char and unsigned char recently. Of course, if you have just learned a computer orProgramming LanguageIt is very simple for people. In my opinion, it is nothing more than the difference between

Program design principles for signed and unsigned numbers: Use a signed number (such as int) when you want to represent a numeric value. When you need to represent a bit collection, use an unsigned number (such as unsigned int).

Inside the computer, all of our information is made up of binary numbers.The symbolic number of the table real method: The number of symbols is in the form of a complement within the computer A positive complement of positive digits

unsigned     is not a negative number, use this type to increase the length of the data! For example if       tinyint max is 127, that       tinyint      unsigned      Max     to     127 * 2 Unsigned property

$sql = "UPDATE ' dzxbbs_common_member ' SET newprompt=newprompt-1 WHERE uid= ' {$uid} '"; The type of newprompt in the ' dzxbbs_common_member ' table is the type of smallint unsigned length 6. When the Newprompt value is 0 o'clock, execute this

Unsigned is not a negative number, use this type can increase the length of the data! For example, if the tinyint max is 127, then the tinyint unsigned maximum can reach 127 * 2 The unsigned property is only for integers, and the binary property is

unsigned is both non-negative, this type can increase the data length!For example if tinyint max is 127, that tinyint unsigned max can go to 127 * 2The unsigned property is only for integral types, whereas the binary property is used only for char

unsigned is not a negative number, use this type can increase the length of the data! For example , if the tinyint max is 127, that tinyint unsigned max You can go to 127 * 2 The unsigned property is only for
