- using c++ plz ............... You build the index by reading through the database account by account, inserting successive (account ID, record number) pairs into the tree as you progress through the file.Given an account ID, retrieval of the corresponding account record is a two-step process. First, you retrieve the data item from the index tree that has the specified account ID. Then, using the record number stored in the index data item, you read the corresponding account record from the database file. The result is an efficient retrieval process that is based on account ID.* Create a program that builds an index tree for the accounts database( Accountants database shown below should be saved in the file accounts.dat). Once the index is built, your program should• Output the account IDs in ascending order• Read an account ID from the keyboard and output the corresponding account recordRecord # Account ID First name Last name Balance0…arrow_forwarduse c++ to Implement a city database using a BST to store the database records. Each database record contains the name of the city (a string of arbitrary length) and the coordinates of the city expressed as integer x- and y-coordinates. The BST should be organized by city name. Your database should allow records to be inserted, deleted by name or coordinate, and searched by name or coordinate. Another operation that should be supported is to print all records within a given distance of a specified point. Use following two classes: struct city { /* add the city attributes and pointers to left and right child nodes*/ } class CityDB { /* create a BST for a City Database here in this class */ } Note: The distance formula is , where x1,y1 are coordinates of city 1 and x2, y2 are coordinates of city 2.arrow_forwarduse c++ to Implement a city database using a BST to store the database records.

Your database should allow records to be inserted, deleted by name or coordinate, and searched by name or coordinate. Another operation that should be supported is to print all records within a given distance of a specified point. Collect running-time statistics for each operation. Which operations can be implemented reasonably efficiently (i.e., in O(log n) time in the average case) using a BST? Can the database system be made more efficiently by using one or more additional BSTs to organize the records by location?arrow_forward

Why is it needed? What are someimportant functions provided in the C programming language for supporting dynamicmemory allocation? Answer using suitable code snippets.arrow_forwardIn this post, we'll take a step back and examine the basics of dynamic memory allocation.arrow_forward
- What is the difference between dynamic and static libraries? A. Dynamic libraries are linked when executable libraries are added to memory, and static libraries are inked alter the program is placed in the memory B. Dynamic libraries are much larger than static libraries because external programs are built in the executable file that is added to memory C. Static libraries are linked when executable libraries are added to memory, and dynamic libraries are linked after the program is placed in the memory D. Static libraries can be linked to any program at run time however, the program has to be loaded for the dynamic library code to be usedarrow_forwardAs a result, when individuals speak about dynamic memory allocation, what precisely do they mean? What's the goal of it all? Many of the most important functions in the C programming language make it feasible to allocate memory in a dynamic manner. Please answer with code examples that are suitable for the situation.arrow_forwardwrite the shortest Kotlin function you can that would not work correctly if implemented using statically allocated activation records. explain why it would fail.arrow_forward
- Explore the concept of "binary executables" and "dynamic link libraries (DLLs)" in software, and explain their functions.arrow_forwardA working C program to transfer the contents of a text file to a linked list. Also, contents should be added to the end of the file(through insertion operation of a linked list) as and when a particular input is entered by the user. Similarly, contents(through deletion operation of a linked list) should be deleted from the file as and when a particular input is entered by the user. Also, through a linked list, a particular string can also be searched from the file. The file should also be updated as and when something is added or deleted. The restriction is that the txt file has a format as follows: 112.33.44.45 Baker 101.22.33.21 Parson and so on.. So the program should have a structure that stores the 4 integer parts of the IP address and one string array being the name followed by the IP address.arrow_forwardWhat is the concept of HeaP file organization?arrow_forward
