oct (octal systems

The Octal Number System is another computer and digital numbering system that uses the Base-8 system. Octal numerals can be made from binary numerals by grouping consecutive binary digits into groups of three (starting from the right).

Each group or set of bits in an octal, binary number has a unique value between 000 (0) and 111 (4+2+1 = 7), and the total amount of bits in an octal, binary number is divided into groups of three.

Including either a 0o prefix or an 8 suffix designates octal numerals.

Octal is base 8.

`0 1 2 3 4 5 6 7`

hex (hexal / hexadecimal system)

Hex means 16. Numbers with base 16 comes under hex number system. It is also called as hexadecimal number system. To represent numbers in this number system it make use of 8 digits only they are digits from 0-9 and letters A-F.

Hexadecimal is a convenient way to describe binary numbers in computers. Computers only work on the binary system, and a byte is usually defined as eight binary digits.

One hexadecimal digit can represent the arrangement of four binary digits. Two hexadecimal digits can represent eight binary digits or a byte.

Hexadecimal is base 16.

`0 1 2 3 4 5 6 7 8 9 A B C D E F`

Conversion from hexadecimal to Octal is possible with two simple steps.

**In the initial step**, we transform the octal numbers into binary.

7 5 1 -> 111 101 001**The next step**is to transform the binary number into the hexadecimal format.

111 101 001 -> 1 E 9

Manually managing blocks of memory in C is like juggling bars of soap in a prison shower: It’s all fun and games until you forget about one of them.
