24
Each
bit is capable of holding two possible values, the number of possible different
combinations of values that can be stored in n bits is 2n. For example:
1 bit can hold 2 = 2^1 = 2 possible
values (0 or 1) 2 bits can hold 2 × 2 = 2^2 = 4 possible values so 8 bits(one
byte) = 2^8 = 256

Differentiate
between random access and sequential access file?
Random
access file:
Random
access files are not in sequence mean its not necessary put that’s thing first
that written first we put any thing from file any where.So
tellg() and tellp() are the two very useful functions while reading from or writing
into the files at some certain position.
Sequential
access file:
Sequential access files are simple
character files. while working with the sequential access files we write in a
sequence not in a random manner

What is a truth Table?
A truth table is a mathematical table used in logic—specifically in connection with Boolean algebra, Boolean functions, and
propositional—to compute the functional values of
logical expressions on each of
their functional arguments, that is, on each combination of values taken by
their logical variables .In particular, truth tables can be used to tell
whether a propositional expression is true for all legitimate input values,
that is, logically valid.

How
learning to design programs is like play soccer?
Learning to design programs is
like learning to play soccer. A player must learn to trap a ball, to dribble
with a ball, to pass, and to shoot a ball. Once the player knows those basic
skills, the next goals are to learn to play a position, to play certain
strategies, to choose among feasible strategies, and, on occasion, to create
variations of a strategy because none fits.
