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?C++: Matching Program Create a datafile that contains the first name, last name, gender, age, height, smoking preference, eye color and phone number. Add a variety of records to the file. A sample file looks like: Write a program that opens the file and reads the records one by one. The program will skip any records where the gender preference is not a match. Of those records that match the gender preference, check to see if the age and height are between the maximum and minum preferences. Then check to see if the smoking preference and eye color are also a match. If at least 3 of the remaining fields match, consider the record a partial match, and print it in the report. If all 4 of the remaining fields match, the record is a perfect match and print it in the report with an asterisk next to it. At the end of the program, close the file and report how many total records there were of the specified gender, how many were a partial match, and how many were a perfect match. See the…C++ Write a program that will allow a user to enter students into a database. The student information should include full name, student ID, GPA and status. The program should allow delete any student based on student ID.

The file which consists of the ordering fields for records is called a. sequential file b. ordered file c. spanned file d. both a and bIn C Programming Language Patient Following System1) Define a struct included patient number, name, age, and disease information.2) Main menu of the program include the following operations:◦ create a patient file with 100 empty records.◦ Insert a new patient record.◦ Find and retrieve patient information.◦ Delete a patient record.◦ Modify a patient record.◦ List all patients information. I need more information for solution.First programming homework Create a class of records for a gradebook called Rec. The data should be private, and should include a firstname, lastname, array of three grades, and a field for average grade. Build two constructors: a default constructor and a constructor that takes the first and last name. Build a function to read the data, either from a file or from cin. The read function reads the two names and three grades, but does not read the average grade. Build a write function that writes the data either to a file or to cout. The write function prints all of the data on one line with spaces between fields. Build a function to calculate the average grade field. Build an overloaded operator == to compare two records. This should be implemented as a friend function. Declare the constructors and functions in the body of the class, but implement them outside the class.

- Add Dist.txt functions in this code Note: Whenever a vaccine is distributed to hospitals, its code and the quantity distributed need to be recorded into a text file named as dist.txt. Each vaccine is expected to be distributed more than once. Hence, while testing the program, there should be at least 10 records created in the dist.txt file. Produce a list of all vaccines and their distributed quantities . The system should allow the employees to list all distributed vaccines and their accumulated quantities read from the dist.txt file.Note: The vaccines and their distributed quantities need to be sorted descendingly (with highest quantity listed first followed by second highest and so on) using Bubble sortbefore displaying on the screen #include <stdio.h> #include <stdlib.h> #include <string.h> // Function Declarations void create_inventory(); void update_vacc_qty(); int search_vaccine(); void display_vaccine(); // Main Function starts here int main() {…Java assignment Create a java program that allows a user to input customer records (ID number, first name, last name, and balance owed) and save each record to a file.A file has r = 20, 000 STUDENT records of fixed length. Each record has the following fields: NAME (30 bytes), SSN (9 bytes), ADRESS(40 bytes), PHONE(9 bytes), BIRTHDATE (8 bytes), SEX(1 byte), CLASSCODE( 4 bytes, integer) MAJORDEPTCODE(4 bytes), MINORDEPTCODE(4 bytes), and DEGREEPROGRAM( 3 bytes). An additional byte is used as a deletion marker. Block size B = 512 bytes. a) Calculate the blocking factor bfr (=floor(B/R), where R is the record size) and number of file blocks b, assuming unspanned organization (a record can’t be split across blocks). b) Suppose only 80% of the STUDENT records have a value for PHONE, 85% for MAJORDEPTCODE, 15% for MINORDEPTCODE, and 90% for DEGREEPROGRAM. We use a variable-length record file. Each record has a 1-byte field type for each field in the record, plus the 1-byte deletion marker and a 1-byte end-of-record marker. Suppose that we use a spanned record organization, where each block has a 5-byte pointer to the next block (this space is not used…
- readEmpFromFile Implement a function readEmpFromFile that takes a FILE * as the only argument and returns a pointer to a struct employee. This function should read the information from the file (reversing what writeEmpToFile does), create a new employee and fill in the data. If the FILE has no more info (is at end of file), this function should return NULL. This function must also ensure any employee actually created (not the NULL) is added to the array (as is done in createEmployee). Change main to load employees from a file using a command called LOAD which is given to the program using (using your readEmpFromFile function you just wrote). void main(void) { int end = 1; char * command; char buff[256]; char * findEmp; char findBuff[256]; char * sortType; char sortBuff[256]; char hire[] = "HIRE"; char list[] = "LIST"; char quit[] = "QUIT"; char find[] = "FIND"; char fire[] = "FIRE"; char _sort[] = "SORT"; char salary[] =…Write C program language Department of computer science offers a set of courses each semester.
