Structural programming and algorithms
The file contains several snippets of text, separated by one empty line, followed by two sets of empty lines of a set of keywords, each keyword in a separate line. It is necessary to construct a directory of frequencies for entering keywords into fragments of the text in the following form: for each fragment it is indicated by its sequential number in the file followed by a list of keywords in the sequence of decreasing their repetition frequencies in this fragment (words that do not occur in this fragment, Do not have to be in the list).
- Describe the data structures for storing the directory in the form of an array, the size of which is equal to the number of fragments of the text, and each element contains the address of the search tree, the information box of each node of which contains the keyword and the frequency of occurrence of the word in the corresponding fragment of the text (the tree is ordered by frequency).
- Record the algorithm for solving the problem.
- Declare a dynamic array to store the directory and ensure memory allocation.
- It is assumed that there is a ready wordInTexts (…) function that searches for a given word in every fragment of the text in a file, generates an array of its occurrence in fragments and returns the address of the beginning of this array. Write a signature for wordInTexts (…). Declare the variables for the array return function and the search tree described in clause 1.
- Write the function of adding information obtained by calling the wordInTexts (…) function for a particular keyword in the array of search trees (p.1).
- Write the function of displaying the directory on the screen as follows: fragment number
A list of keywords in the order of reduction of frequencies (words with a zero frequency are not deduced).
Object Oriented Programming
The file contains several snippets of text separated by one empty line, followed by two sets of keywords followed by two empty lines for each fragment – their keywords in a separate line, separated by one or more spaces (the keyword does not contain spaces). It is necessary to construct a directory of the frequencies of the appearance of the keywords in the text fragments in the following form: for each fragment it is indicated by its serial number in the file, followed by a list of its keywords, indicating the frequency of their appearance in descending order.
- Develop a basic TextFragment class to work with a piece of text, provide the necessary set of constructors, operations to add and delete a set of characters at a given position.
- Develop a derived TextFragmentWithKeyWords class to work with a piece of text in order to search for keywords specified in this class. Provide the necessary set of constructors, operations of adding and removing keywords, as well as the operation of determining the frequency of each keyword in the fragment.
- Create a class-container of objects of the class TextFragmentWithKeyWords and initialize its elements with the data from the file.
- Apply the TextFragmentWithKeyWords class operations to construct the desired directory task.
- Ensure results are displayed as follows:
A list of keywords in the order of reduction of frequency (words with zero frequency are not deduced).
Description of the subject area
You work in a company that sells spare parts for automobiles. Your task is to monitor the financial side of the company.
The bulk of your business activity is related to working with suppliers. The company has a certain set of suppliers, for each of which the name of the supplier company is known, address and telephone. You will acquire parts from these suppliers. Each item along with the name is characterized by the article and the price (the price is constant). Some suppliers may supply the same parts (same article). Every fact of purchase of spare parts from suppliers is recorded in the database, besides obligatory for storage is the date of purchase and the quantity of purchased parts.
- Construct an ER diagram of a domain (a conceptual database model).
- Construct an ER-diagram of the base diagram in the form of a set of relationships and relationships between them.
- For each relationship define: keys (primary and external), attribute domains, mandatory attributes.
- Implement the following queries in SQL language:
- Repeat the name of all supplier companies that shipped the “Stoy” item for the current month. Sort by the name of the supplier company. Effective table: <company name, phone>.
- Output the names of those parts that were never delivered during the current year without repeating. Effective table: <item name>.
- For each item name, show the total number of parts purchased in the current month. The resultant voter should not have details that were not purchased this month. Effective table: <item name, total quantity>.
- Give the key to the relation. What properties should a key be? What is the difference between the primary and the potential key? What is a superkey?
- Name the 4 main SQL statements of the DML language operator.
