TAILIEUCHUNG - Lecture note Data visualization - Chapter 8

This chapter presents the following content: Data structures and problems with C, pointers, arrays and structures, types of arrays, use of vectors. | Lecture 08 Recap Data Structures and Problems with C Pointers Arrays and Structures Types of Arrays Use of Vectors Resizing the Vector One limitation of primitive arrays is that, once they have been declared, their size can never change However, we can use resize to change the size of a vector Pointers are used to give the illusion of an array that can be resized Example arr is representing a 10-element vector Somewhere, buried in the implementation then, memory is allocated for 10 elements Suppose that we would like to expand this memory to 12 elements The problem is that array elements must be stored in contiguous memory and that the memory immediately following arr might already be taken Continued . Do the following We remember where the memory for the 10-element array is (the purpose of original) We create a new 12-element array and have arr use it. We copy the 10 elements from original to arr; the two extra elements in the new arr have some default value We inform the system .
