A movie file has the following record structure: name of the movie producer director type production cost Assume that the name of the movie is the primary key of the file. The field type refers to the type of the movie, for example, drama, sci-fi, horror, crime thriller, comedy and so forth. Input a sample set of records of your choice into the movie file.i) Implement a primary index-based ISAM file organization.ii) Implement secondary indexes on director, type and production cost.iii) How could the secondary index-based file organization in Programming Assignment 3 (ii), be used to answer a query such as “Who are the directors who have directed films of the comedy or drama type, who have incurred the highest production cost?

- (Data processing) A bank’s customer records are to be stored in a file and read into a set of arrays so that a customer’s record can be accessed randomly by account number. Create the file by entering five customer records, with each record consisting of an integer account number (starting with account number 1000), a first name (maximum of 10 characters), a last name (maximum of 15 characters), and a double-precision number for the account balance. After the file is created, write a C++ program that requests a user-input account number and displays the corresponding name and account balance from the file.arrow_forwardin the FILE structure : What two fields we used to determine the size of the internal buffer allocated : Group of answer choices read_ptr and write_ptr base and end pointer flags and fileio all of the abovearrow_forward5. Assume a file system is using combined indexing scheme to keep track of the blocks allocated to a file, as in Linux/Unix file system. In the inode of a file, there are 12 direct pointers, one single-indirect pointer, one double-indirect pointer, and one triple-indirect pointer. Assume the size of a disk block address (i.e., disk pointer size) is 8 bytes. Assume block size is 4 KB. a) What is the maximum file size? b) How many index blocks are required for files of size 30 KB, 256KB, 15 MB, 512 MB, 32 GB? c) Assume nothing is cached (no disk caching applied in the system) and we know the disk location of the inode of a file of size 1 GB. How many disk accesses are required to access a byte at offset 2^14 (16K) in the file? How many disk accesses are required to access a byte at offset 2^26 in the file?arrow_forward
- Program this Sometimes data comes in as a structured format that you have to break down and turn into records so you can process them. CSV, or comma-separated values, is a common standard for doing this. Construct a program that reads in the following data file: Lee, Jason, 55908 Flores, Jim, 56500 Cruz, Aaron, 46000 Cruz, Chris, 34500 Swift, Geoffrey, 14200 Xiong, Fong, 65000 Zafra, Sabrina,51500 Process the records and display the results formatted as a table, evenly spaced, as shown in the example output. EXAMPLE OUTPUT Last First Salary $65,000 $56,500 $55,900 Xiong Fong Flores Jim Lee Jason Zafra Sabrina Cruz Aaron Cruz Chris Swift $51,500 $46,000 $34,500 Geoffrey $14,200 CONSTRAINTS 1. Write your own code to parse the data. Don't use a CSV parser 2. Use string formatting to properly space out the columns. Make each column one space longer than the longest value in the column. 3. Format the salary as currency with dollar signs and commas. 4.

- Array/File FunctionsWrite a function named arrayToFile. The function should accept three arguments:the name of a file, a pointer to an int array, and the size of the array. The functionshould open the specified file in binary mode, write the contents of the array to the file,and then close the file.Write another function named fileToArray. This function should accept three arguments: the name of a file, a pointer to an int array, and the size of the array. Thefunction should open the specified file in binary mode, read its contents into the array,and then close the file.Write a complete program that demonstrates these functions by using the arrayToFilefunction to write an array to a file, and then using the fileToArray function to readthe data from the same file. After the data are read from the file into the array, displaythe array’s contents on the screen.arrow_forwardA movie file has the following record structure:name ofthe movie producer director type productioncostAssume that the name of the movie is the primary key of the file.

Your task is to readthe file, count the word frequency by ignoring the letter case, output the frequently used words (i.e.,the words occurred more than once) and the most frequently used word among all of them.Lab Scenario: Count the word in a document1. The program reads from an already provided input file: “document.txt”, which containsseveral paragraphs separated by an empty line.2. You will perform the file open operation. And then perform the read operation with your choice ofread functions and read the content of the file.3. Once you are done reading, start processing the contents of the file using a dictionary where thekey would be the word in lowercase and the corresponding values would be word frequency whichwill be the number of occurrences in the…arrow_forward
- - PROJECT REQUIREMENTS Choose a programming project application to be developed, then design and implement the programming elements according to your creativity using C++ language. The application must demonstrate the integration of file I/O, records(struct), array and functions. You may follow the general framework for the implementation phase as highlighted below: Read data from file. Store data into a struct array. Process the data using functions. You may pass variables, one dimensional array, two dimensional array, struct variable or struct array to functions, where appropriate. Display the output to the screen, where appropriate. Write the output file, where appropriate.

The program obtains the file name from the command line. Each line of the file will have the following form: item, mm-dd-yyyy, price For example, suppose that the file contains the following lines: 123, 12.00, 12/25/2006 124, 18.30, 1/10/2020 Expected output: Item Unit Purchase Price Date 123 $ 12.00 12/25/2006 124 $ 18.30 1/10/2020arrow_forward
