Hello
I am looking for help in understanding the difference between following 2 declarations:
1.
union u2 { unsigned int urow2; struct s2 { unsigned int p32 : 1; unsigned int p31 : 1; unsigned int p30 : 1; unsigned int p29 : 1; unsigned int p28 : 1; unsigned int p27 : 1; unsigned int p26 : 1; unsigned int p25 : 1; unsigned int p24 : 1; unsigned int p23 : 1; unsigned int p22 : 1; unsigned int p21 : 1; unsigned int p20 : 1; unsigned int p19 : 1; unsigned int p18 : 1; unsigned int p17 : 1; unsigned int p16 : 1; unsigned int p15 : 1; unsigned int p14 : 1; unsigned int p13 : 1; unsigned int p12 : 1; unsigned int p11 : 1; unsigned int p10 : 1; unsigned int p9 : 1; unsigned int p8 : 1; unsigned int p7 : 1; unsigned int p6 : 1; unsigned int p5 : 1; unsigned int p4 : 1; unsigned int p3 : 1; unsigned int p2 : 1; unsigned int p1 : 1; }ss2; }myunion2[16];
2.
union u2 { unsigned int urow2[16]; struct s2 { unsigned int p32 : 1; unsigned int p31 : 1; unsigned int p30 : 1; unsigned int p29 : 1; unsigned int p28 : 1; unsigned int p27 : 1; unsigned int p26 : 1; unsigned int p25 : 1; unsigned int p24 : 1; unsigned int p23 : 1; unsigned int p22 : 1; unsigned int p21 : 1; unsigned int p20 : 1; unsigned int p19 : 1; unsigned int p18 : 1; unsigned int p17 : 1; unsigned int p16 : 1; unsigned int p15 : 1; unsigned int p14 : 1; unsigned int p13 : 1; unsigned int p12 : 1; unsigned int p11 : 1; unsigned int p10 : 1; unsigned int p9 : 1; unsigned int p8 : 1; unsigned int p7 : 1; unsigned int p6 : 1; unsigned int p5 : 1; unsigned int p4 : 1; unsigned int p3 : 1; unsigned int p2 : 1; unsigned int p1 : 1; }ss2[16]; }myunion2;
Basically i want to initialize 16 unsigned int variables, urow2, and later access each of thir bits separately.
Any help would be great.
