Data Types (3)

• In C/C++ Ada and Pascal string data are stored with a special delimiter
• Forton 90 and Visual Basic supports stings as primitive data types
• Basic operations on strings are assigning, joining and comparing

 

• Primitve and composite data types are suffiecient solving simple problems
• The ear;y computer applications depended on the vuilt in data types of programming langyages
• Primitve types are not always sufficient to solve advanced problems
• Need for advanced data types arose due to the new paradigm of object oriented approach
• Data structures are meant to serve these special needs
• It is a programming construct that stores a collection of data items
• Dta structure are not just an extention of composite data ypes

Thow significant diferences are
First data structure encompassed primitve and compostire data types
Second, data structures it includes some kind of relationship among the data items. For example, string has definite order of organized character.
