How many bytes of memory is occupied by the A array? d)Each pixel for a High Definition display uses 4 bytes consisting of RBGW [Red, Blue, Green, White). Display consists of 1200 x900 pixels per frame. How much memory is needed per frame in bytes? d Memory per frame__.... e) What is the minimum display rate in bits per second, under conditions of part (d) above e display rate_-- 1) Steganography uses least significant bit of each RBGW byte. In one frame, how many bytes of Steganography data is hidden? Can t Steganography data be hidden in the most significant bit ? lyes, no, does not matter) e Ans _Most significant bit?

Explanation / Answer

Answering your first question with sub-parts clearly:

3
a)
y = (27 + 91 + 39) * 2 = 157 * 2 = 314;
z = (2 + 39) * 42 = 1722;

b)
Q will be of type double, as 3.2 square is a double and then this double is again passed to the function.
Q = ((3.2)^2)^2 = 104.8576

c)
Yes, The class can be declared after the main program also, but main program should not be using it.

d)
Inline functions in c++, allow function code to be replaced on stack: True

e)
104 cards, they can be represented with next bigger number, which is power of 2.
That will be 128, which is 2^7=> so 7 bits should be sufficient.

f)
Yes, in java, variables can be declared anywhere in the program code. I assume, program code means inside the class, as variables can not be declared outside the class.
