Basic data types |
C/C++ statically typed languages. Before we can store certain values in the computer memory, we need to declare their data types.

:::info
A decimal integer cannot start with 0, in that case it is considered octal
base. For example, 076 denotes 63 in decimal notation.

:::tip Good to know
For numeric data types that span multiple bytes, the order of arrangement of bytes is important. Depending on the processor architecture, there are two formats: big endian and little endian.
Big endian: the most significant bits occupy the lower address. This representation is used in powerpc processor.
Little endian: the least significant bits occupy the lower address. This format is used in all x86 compatible processors.
