In this video we will learn what are data-types and create variables of different data-types in C.
There are two types of data-types
I. Primitive data-types
II. User defined data-types
Primitive data-types in C are :-
- int
- float
- double
- char
- void
- short
- long
- signed
- unsigned
Data-types they storage size and value range :-
Type | Storage size | Value range |
---|---|---|
char | 1 byte | -128 to 127 or 0 to 255 |
unsigned char | 1 byte | 0 to 255 |
signed char | 1 byte | -128 to 127 |
int | 2 or 4 bytes | -32,768 to 32,767 or -2,147,483,648 to 2,147,483,647 |
unsigned int | 2 or 4 bytes | 0 to 65,535 or 0 to 4,294,967,295 |
short | 2 bytes | -32,768 to 32,767 |
unsigned short | 2 bytes | 0 to 65,535 |
long | 4 bytes | -2,147,483,648 to 2,147,483,647 |
unsigned long | 4 bytes | 0 to 4,294,967,295 |
