signed int

A bit segment (Bit-field) defines the space occupied by a member variable in a struct (or union) in bits. A struct (union) that contains a bit segment is called a bit segment structure. The use of bit-segment structure can not only save space, but

MAD (Libmad) is an open source High-precision MPEG Audio Decoder library that supports MPEG-1 standards. Libmad provides 24-bit PCM output, fully fixed-point computing, and is ideal for use on embedded hardware platforms without floating-point

1. Signed int vs. unsigned int#define Totol_elements (sizeof (a)/sizeof (A[0)), int main () {int a[] = {23,24,34};int d = -1;if (dResult analysis: sizeof () returns an unsigned integer, so the value totol_elements in the above code is the unsigned

just like int A; int can also be decorated with other modifiers. In addition to the void type, the basic data types can be preceded by various types of modifiers, with the following four types of type modifiers:1.signed----with symbols, can be

The conversion function of MySQL IP to int Select Inet_aton (IP) from table_name; Network address: 192.168.33.123 The maximum of each value does not cross 255, which is hexadecimal FF, and the maximum value of two byte is 255. This way, you can use

Some data is stored without the need to occupy a full byte, only one or a few bits is required. For example, the switch is only power and power off two states, with 0 and 1 is sufficient, that is, with a binary. It is based on this consideration
