C Data Types

Having read this section you should be able to:

1. declare (name) a local variable as being one of C's five data types
2. initialize local variables
3. perform simple arithmetic using local variables

 There are five basic data types associated with variables:

1. int (4 bytes size)- integer: a whole number.
2. float (4 bytes size)- floating point value: ie a number with a fractional part.
3. double (8bytes size)- a double-precision floating point value.
4. char (1 bytes size)- a single character.
5. void - valueless special purpose type which we will examine closely in later sections.
