typedef struct { int item_id; char item_name[8]; } tRecord; Given a file containing N of the above records that are shuffled, write the C code that generates a new file with these records sorted in descending (decreasing) item_id. Note that you can assume item_id of each record is a positive number. Write maximum 40 lines of code or upload your answer.
In this assignment you will be writing several functions that process files and dictionaries to encryptand decrypt messages. A dictionary will be used to create a random substitution cypher. Each letterof the alphabet will be mapped to another random letter in the alphabet. No letter will map or bemapped to any duplicate letter. For example given the partial dictionary below you can encrypt amessage.Be sure to use the starter file provided so you can see the appropriate outputs. Be sure to downloadand place the appropriate text files in the same directory as your python file. You only need to submityour python file.Partial Dictionary: {d : a, e: f, h : b, l : p, l : e, o : j, r: m, w: i}originalMessage = “hello world” → encryptedMessage = “bfeej ijmea” Part 1 - Encrypt a Message: You will write 2 functions to build a dictionary and encrypt a messageFunction buildCypher() → dict:This function is to build a dictionary that can be used to create a random substitution cypher.

SAME PARAMETERS: In the RENTALS table shown in fig 2, 40 customers have created 50 rental contracts over time. A RENTALS record is 122 bytes and the block size for your OS is set to 1024 bytes with each block having a 1 byte pointer to the next written block as well as a 1 byte pointer to the next physically consecutive block. Assuming spanned organization, how many blocks do you estimate the RENTALS file is using at its current size? multiple choice a.50 b.6 c.400 d.7

IN C PROGRAMMING LANGUAGE AND COMMENT EVERY LINE SO I COULD UNDERSTAND EVERY STEP PLEASE, Write a program that implements the binary search for a set of integers stored in a data file. (Note that the data set in sorted in an ascending order).
Do not copy paste from any source else downvote Write a void function that will merge the contents of two text files containing chemical elements sorted by atomic number and will produce a sorted file of binary records. The function’s parameters will be three file pointers. Each text file line will contain an integer atomic number followed by the element name, chemical symbol, and atomic weight. Here are two sample lines: 11 Sodium Na 22.99 20 Calcium Ca 40.08 The function can assume that one file does not have two copies of the same element and that the binary output file should have this same property. Hint: When one of the input files is exhausted, do not forget to copy the remaining elements of the other input file to the result file.
