C AND operators .

1. logical AND (&&)

2. bit wise AND (&)

Decision control structure if condition logical && .

if( percentage >= 60 && percentage < 70)

{

printf("First Class with distinction\n");

}

printf statement control if conditions true

.

bit wise AND (&) . फ expression व व

bits व . Bit wise operation returns 1 when both of its operands are 1. ग bit

32 bits graphics 2 words information . In 32 bit dWord there are 4

distinct values.

Low byte is for Blue (0 to 7)

The next significant byte is value for Green (8 to 15)

Then a byte for Red (16 to 23)

High byte is for Transparency (24 to 31)

color dWord

AAAA AAAA RRRR RRRR GGGG GGGG BBBB BBBB

32 bit dWord integer Red color extract ? ए

bits zero (0) Red byte . bit wise &

(AND) operator . So we will be having one variable mask

o (Zero) erase .

mask ...?
