The people who create the language take the liberty of deciding the size of data types in a programming lanauage.
If you (as a programmer) create your own custom data type, for example by defining a class, then you decide what goes into it - for example, in Java, if one of the pieces of data requires an integer, you have the choice of storing it as an int, which uses 4 bytes, or as a long, which uses 8 bytes (and permits larger numbers).
char is a primitive data type and depends on the programming language and the operating system.
sizeof is your friend.
One of them is signed, the other is unsigned.
Primitive data types are smaller in size and hence are efficient in processing and use the least bandwidth.
You can not change the range of a data type. It is a function of the implementation and is dependent on the word size of the implementation's computer hardware.
Different languages have different data types. But basically, each class can be considered a different data type. For example, if a language doesn't have a data type for dates, create a class, with fields (or properties) to store day, month, year; if your language doesn't have complex numbers, create a class with two fields of some real type to store the real and the imaginary part; if your language doesn't have a data type to store information about a font (its name, size, and characteristics like being or not being bold), create a class to save information about a font, etc.Different languages have different data types.

arrays in C are the data types which have collection of same type of data together store a fixed-size s of elements .

it is not necessary to have same size for all members in an union ..because unions holds different data types..

you can just use sizeof. sizeof(int) for example
bit size is a wordlength of one memory location
