Each variable in C has an associated data type. Each data type requires different amounts of memory and has some specific operations which can be performed over it. Let us briefly describe them one by one:
Following are the examples of some very common data types used in C:
- char: The most basic data type in C. It stores a single character and requires a single byte of memory in almost all compilers.
- int: As the name suggests, an int variable is used to store an integer.
- float: It is used to store decimal numbers (numbers with floating point value) with single precision.
- double: It is used to store decimal numbers (numbers with floating point value) with double precision.
