### What are the advantages of hexadecimal number system?

Each hexadecimal digit represents four binary digits (bits)
(also called a "nibble"), and the primary use of hexadecimal
notation is as a human-friendly representation of values in
computing and digital electronics. For example, binary coded byte
values can range from 0 to 255 (decimal) but may be more
conveniently represented as two hexadecimal digits in the range 00
through FF. Hexadecimal is also commonly used to represent computer
memory adresses.

### Why machine language uses hexadecimal?

Because Hexadecimals are easy to write, remember and most
important uses lesser number of characters to write a program. For
e.g. Let's take a simple example - To write value of 255, binary
number system would take 8 characters (255 (base 10)= 11111111
(base 2)) to punch from keyboard, decimal number system will take 3
key punches and hexadecimal will take only 2 key punches (255 (base
10) = FF (base 16)).
So it is much easier to write program in hexadecimal than any
other system.

### How do you write bytes in Turbo C plus plus header files?

Bytes can be written using hexadecimal, octal or decimal
notation. A numeral with no prefix is always regarded as decimal.
If prefixed with a leading zero it is deemed octal and if prefixed
with 0x it is deemed hexadecimal. The following shows the three
ways to write the decimal value 255:
255 (decimal)
0377 (octal)
0xff (hexadecimal)
Hexadecimal is the generally the most convenient method of
notation since each hexadecimal digit represents exactly 4-bits (a
half byte or a nybble). An octal digit represents exactly 3 bits
and is useful for notating bytes in groups of 3 bits. A 24-bit
integer is both a multiple of 3 and 4 so it can be notated using 8
octal digits or 6 hexadecimal digits.
Individual bytes are best stored using the uint8_t alias
(defined in the <cstdint> standard library header) as this
guarantees an 8-bit byte in the positive range 0 to 255 decimal. To
store several contiguous bytes, use a vector of uint8_t:
std::vector<uint8_t> bytes;
bytes.push_back (255);
bytes.push_back (0377);
bytes.push_back (0xff);
The above example pushes the value 255 onto the back of the
vector three times, using decimal, octal and hexadecimal
notation.
You can also write contiguous bytes in multiples of 2, 4 and 8
bytes using uint16_t, uint32_t and uint64_t aliases respectively.
Thus if you need a 64-bit value, use the uint64_t alias.
uint64_t word = 0xffffffffffffffff; // maximum value

### What is the square root of blue?

In HTML, the hexadecimal code for the color blue is #0000FF. In
hexadecimal numbers (or base 16 numbers), F is the equivalent of
15. So, 0000FF is 255 in decimal form. The square root of 255 is
approximately 15.968719423.
So, I believe it is safe to say that the square root of blue is
approximately equal to 15.97.
The question asked for the square root of blue, not its
hexadecimal equivalent. The question really asks what color
multiplied by itself would produce blue. The answer is simply blue.
Blue times blue equals blue. There is no negative blue equivalent.
No matter how many copies of blue you have, you still have
blue.
