Task 2: Printing the time that the file path was created (50 points) The stat system call can access a file by name and retrieve file status information. It is given by: int stat (const char *pathname, struct stat *buf); This system call retums a stat structure (both the function and struct are called stat), which contains the following fields: struct stat { dev_t st_dev; /* ID of device containing file */ ino_t st_ino; /* inode number */ mode_t st_mode; /* protection */ nlink t st nlink; /* number of hard links */ uid t st uid; /* user ID of owner */ gid_t st gid; /* group ID of owner */ dev_t st_rdev; /* device ID (if special file) */ off t st size; * total size, in bytes */ blksize_t st_blksize; blocksize for file system IO */ blkent t st blocks; /* number of 512B blocks allocated */ time_t st_atime; /* time of last access */ time_t st_mtime; * time of last modification */ time_t st_ctime; /* time of last status change */ On success, zero is returned. On error, -1 is returned, and…

A file has r=20000 STUDENT records of fixed-length. Each record has the following fields: NAME (30 bytes), SSN (10 bytes), ADDRESS (40 bytes), PHONE (9 bytes), BIRTHDATE (8 bytes), SEX (1 byte), MAJORDEPTCODE (4 bytes), MINORDEPTCODE (4 bytes), CLASSCODE (4 bytes, integer), and DEGREEPROGRAM (3 bytes). Suppose the block size is 512 bytes.   (a) Calculate the record size R in bytes.   (b) Calculate the blocking factor (number of tuples per block) and the number of blocks required. (c) Calculate the average block accesses it takes to find a record by doing a linear search on the file. (d) Assume the file is ordered by SSN; calculate the block accesses takes to search for a record given its SSN value by doing a binary search.

Filename for submission: atm.py Consider the software that runs in an Automated Teller Machine (ATM) machine. One task that must be able to be performed is to determine the type (denomination) of currency and the numbers of bills (aka "banknotes" for those of you not from North America) for each type dispensed. A requirement is that our ATM use the fewest number of bills that it can to dispense the specified amount of money. It only dispenses fifties, twenties, tens, fives, and ones. Design and implement program that writes out what bills would be dispensed if this machine existed for the amount of money that was asked for by the user. Note: This assignment requires you to pay particular attention to your output formatting. Be precise in your spelling and spacing. Match the textual prompts exactly as you see in the example below in order to pass our automated testing suite. You may copy the prompts given here to use in your code: Welcome to PDQ Bank! Amount to withdraw? $ Cha-ching!…

Computer Science Objective You have a compressed file named `gzamlet.Z` of gzip type in Lempel-Ziv (LZ77) encoding. File contains Shakespeare's play Hamlet. Write a command that finds the line number of the text file where the iconic phrase "To be, or not to be" is found. Count the blank lines in your tally. Constraints =========== - You are prohibited from using intermediate files. You must place an order and/or use tubes. index ====== - The `zcat` command allows you to decompress an archive and send its contents to standard output.
