Type Specification

Definition: Declaring a Variable's Data Type

Categories of Type Specification:

Explicit, using Declaration Statements. E.g., C++, Java, Modula-2
```
  int number;
  char initial;
```
Implicit, using Default Conventions.
- FORTRAN 77:
  - Variables whose names begin with I..N are INtegers
  - Other variables are REAL
- QBasic:
  - Variables declared without a data type are considered to be variant types
```
  Dim Hours as Integer     'Hours is an Integer variable
  Dim query                'Query is a variant data type
```
