26. What is Data structure ? A data structure is a specialized format for organizing and storing data. data structure is a particular way of organizing data in a computer so that it can be used efficiently. A Data Structure is a mathematical or logical way of storing/organizing data in the memory that not only consider items stored but also relationship among them. 26 Department of CSE and IT

27. Example of data Structure Arrangement of words in Dictionary 27 Department of CSE and IT

28. organizing words in Dictionary Alphabetical order 28 Department of CSE and IT

29. Advantage Searching of Data becomes easy. Accessing data becomes quick and efficient. It allows proper use of the available space. 29 Department of CSE and IT

30. Classification 30 Department of CSE and IT

31. Definition Primitive data structures: These are the data structures that can be directly operated upon the machine instructions. Example: int , char, float, double, pointer. Non-Primitive data structures : These are those data structures that are derived directly from the primitive data structures. Example: class, structure, array, linked lists. 31 Department of CSE and IT

32. Answer this What is Data structure? Give some examples of Data Structure A data structure is a way of organizing data that considers not only the items stored, but also their relationship to each other. Advance knowledge about the relationship between data items allows designing of efficient algorithms for the manipulation of data. int , float, Array, Stack, Queue, Link List etc 32 Department of CSE and IT

33. Some More Give a real-world example of Data Structure. List some Primitive Data Structure List some Non-primitive Data Structure Books in Library Words in Dictionary int , float, char, double, Pointer Array, Stack, Queue, Link List, Tree, Graph 33 Department of CSE and IT

34. Assignment Questions What do you mean by Data Structure ? Why Data Structure is important ? Explain the classification of data structure. What is the Difference between primitive and non-primitive data structure? Department of CSE and IT 34
