Transcript of Introduction to Data Types

Newer programming languages have only
5
categories:
integer
real
char
bool
enumeration type
-Building block for structured data types
-Three categories of simple data:
Integral
: Data types that deals with integers or numbers without a decimal (further classified into nine other specific categories)
Floating-Point
: Data types that deal with decimal numbers
Enumeration
: User-defined data type (method that allows programmers to create their own simple data types)
Data Type:
A set of values put together with a set of operations
Simple Data Types
DATA TYPES
Objective C++: Manipulate data.

Different
programs manipulate
different
data.
C++ categorizes data into different types, and only certain operations can be performed on particular types of data.
Reflecting these kinds . C++ has built-in checks to guard against errors.

C++ DATA TYPES: (
3

types)
Simple
Structured
Pointers
Integral
Floating-Point
Enumeration
Why are there so many categories for the same data type? - Each data type has a different set of values that go along with it.
The data type you use depends on how
large
a number your program needs to deal with
