1st...what is the function of flush commond?

1): when we specify the buffer size, normally the operating system or compiler does this for us. A typical size of buffer is 512 bytes. When the information is of 512 byte size, output will take place. But in the program, we may want at some point that whatever is in the buffer, show them. For that purpose the normal mechanism is flush. Flush the stream. The flush command forces the data from the buffer to go to its destination which is normally a screen or file and make the buffer empty.Lec 34

12 & 8 = (1000) 2 =________. & is used to AND two numbers bit-wise Select correct option:

4 8 6

12

Is ka answer 8 hy, see handouts page number 246.

Truth table for &

Bit1      Bit2       Bit1 & Bit2

1          1          1 1       0          0 0       1             0 0       0          0

Therefore, when we apply the conditions, we get

12 = 1 1 1 0 (binary conversion of 12)

8 = 1 0 0 0 (binary conversion of 8)
