例如,CPU的状态寄存器,按位段类型定义如下: struct status i unsigned sign /*符号标志* unsigned zero: 1 /*零标志* unsigned carry /*进位标志* unsigned parity: 1 /*奇偶/溢出标志* unsigned half carry: 1 /*半进位标志* unsigned negative /*减标志* 3 flag例如，CPU的状态寄存器，按位段类型定义如下： struct status { unsigned sign: 1; /*符号标志*/ unsigned zero: 1; /*零标志*/ unsigned carry: 1; /*进位标志*/ unsigned parity: 1; /*奇偶/溢出标志*/ unsigned half_carry: 1; /*半进位标志*/ unsigned negative: 1; /*减标志*/ } flags;
