===Data Types===

[[Data type|Data types]] indicate both how much data is stored as well as how that data can be processed and represented.  Some languages (such as [[PHP]]) are typeless, indicating that variables can store any type of data.  Other languages (such as [[C++]]) are strictly typed, indicating that each variable can only store data of a given type.

[[Data type|Data types]] indicate both how much data is stored as well as how that data can be processed and represented.  Some languages (such as [[Python (programming language)|Python]]) are typeless, indicating that variables can store any type of data.  Some (such as [[PHP]]) are loosely typed, which means that variables can be given a defined type, but this is not always strictly enforced. Other languages (such as [[C++]]) are strictly typed, indicating that each variable can only store data of a given type.
