A temperature file consists of five records, each containing a temperature in degrees Fahrenheit. A program is to be written that will read the input temperature, convert it from degrees Fahrenheit to degrees Celsius and print both temperatures in two columns on a report. Column headings, which read ‘Degrees F’ and ‘Degrees C’, are to be printed at the top of the page. What ist he best solution algorithm to successfully implement the above question?
Problem Definition You are provided with a text file (employees.txt) containing a number of text lines. Each line contains a record of one employee. Each record has three attributes: Title: string, Prof. (Professor) or Dr. (Doctor). First and Last names: string. Salary: float number. The attributes are separated by the character (',). Figure 1.a, 1.b, and 1.c show a sample of employees.txt files.

Instructions Write a program to implement the algorithm that you designed in Exercise 20 of Chapter 1. (Assume that the account balance is stored in the file Ch4_Ex15_Data.txt.) Instructions to Exercise 20 of Chapter 1 have been posted below for your convenience.
main() will call create() and then call retrieve() create() will prompt the user to enter any number of course name / grade pairs and write them to a file named grades.txt. Pressing Enter with no input value on the course name will exit the loop, close the file, print "File was created and closed" and return the bool value True to the main() retrieve() will open and read grades.txt. The function then will print the course names and scores as shown below. The average score should be calculated as well as a simple GPA and displayed to two decimal places and then return variable used for the GPA to the main() . See sample run below in which 4 course names were entered, but note that more or fewer courses could have been entered. Enter course name or Enter to quit: CPO1000 Enter grade (integer) achieved: 96…
Assume that a file contains students' ids, full names, and their scores (Assignments grade, quizzes grade, Midterm grade, Practical exam grade, and final exam grade) (each column is separated by $). You are required to write a C program to do the following: Using the concept of parallel arrays create records for students with above attributes (id, full name, score).(you are not allowed to use structure) • Ask the user to enter the input file name and read it (suppose that, there are different files you could read data from). Read the data from the file and store it in record for students, which has IDs, Names, and Scores. The IDs should be declared as integers, the Names as a two-dimensional array of characters and the Scores as doubles. Assume that the maximum length of full name of any student is 50 characters. Also, you may assume that there will be No more than a 1000 student records in the file. • Calculate the final grade as the flowing: Grade= (Assignment)*15%+(Quizzes)…
program by using "C language" my student number is :1910206534 The information of all students taking the programming course is kept in a random access file with the struct given below. Your code should swap the information of two records in the file. Write the code that performs this operation. Note: The position of the 2 records that you need to swap like this:The position of the first record is the sum of the first 5 digits of your student number.The position of the second record is the sum of the last 5 digits of your student number.
True or FalseAs items are read from the file, the read position moves forward, toward the end of the file.
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() {…
A 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. Thefield type refers to the type of the movie, for example, drama, sci-fi, horror, crimethriller, comedy and so forth. Input a sample set of records of your choice into themovie file.i) Implement a primary index-based ISAM file organization.ii) Implement secondary indexes on director, type and productioncost.
question] ll-based questions 1. Write a program that takes a person's details (name, age and a city), and writes to a file (persons.txt) using a loop repeatedly. The program terminates on entering any key by the user, except on (Y or y) key. Sample output of the first run of the program is shown below: Enter name: John Enter age: 20 Enter city: Sydney Data saved: John 20 Sydney Press (Y or y) to add another person, or any key to exit A Education 302 Elizabeth Street, Sydney http://www.win.edu.au/ }
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…
