Explanation / Answer

Q.1.

The 3 major items associated with every variable is Value hold by the variable, No. of bytes and third and most important one is the address where the variable will be stored. Hence Answer is D. Address

Q.2

The address of a variable is always the Memory Location of the First byte reserved for the variable. As the adress is always considered from the very first Bytes. Hence the answer is A. First.

Q.3

All pointers such as Char, Int, Float are same As it simply stores the address and which is unsigned Int.

For 32-bit system 4 bytes is required and for 64-bit system 8 bytes is required. I suggest you to ask the examiner to clarify whether this question is for 32 bit system or it is for 64 bit system.In general considering 32 bit system The answer is B.FOUR(But ask examiner as i have written above).

Q4.

Pointer are just like any other variable which is used to store some data. Pointers stores address which is in Hexadecimal number which represents memory. Hence the answer is C. Variables
