1. Create a simple C program to generate a file consisting of the word "Hello", one million bytes of blank space (null bytes), and then "world\n", but that consumes only a small number of blocks on disk while having a logical size of 1,000,011 bytes.
2. Create a C program "mycopy.c" that takes two filenames A and B as command line arguments. This program should copy the contents of A to B, making B a byte-for-byte copy of A. Zero bytes in A should consume little to no space in B. (Hint: You'll have to use the sparse file creation technique of the previous question here.)
3. Describe a simple way an attacker could get root access on a system if loopback mounts were permitted for non-privileged users.
Write a program to calculate the volume flow rate in cubic feet per second of water flowing through a pipe of diameter d in inches and a velocity of v feet per second. The formula for the flow rate is given by: Where area = ?d^2 / 4 equation in sq..
Demonstrates your thought process and steps used to analyze the problem. Be sure to include the required input and output and how you will obtain the required output from the given input
Write a program that asks for the starting time and the number of minutes of the call, and display the charges. The program should ask for the time to be entered as a floating-point number in the form HH.MM. For example, 07:00 hours will be entered a..
Refer to the figure above. Assume you add the numbers 23, 76, 64 in this order. The output of the program will be which of the following?
Write a program that decodes a message that was encoded using a random key. These keys work similar to a magic decoder wheel (where 'A' encodes to 'F', 'B' encodes to 'G', 'C' encodes to 'H', etc)except there is a random mapping from one letter to..
Write a function day_of_year(month, day, year) that returns the day of the year (an integer between 1 and 366) specified by the three augments.
Design a class called NumDays. The class's purpose is to store a value that represents a number of work hours and convert it to a number of days. For example, 8 hours would be converted to 1 day, 12 hours would be converted to 1.5 days, and 18 hou..
Scripts can be great tools. Describe one task where it would be suitable / efficient to use a script and another task where it might not be. Provide a rationale for your response.

Compare and contrast the mode operators ios::in, ios::app, and ios::out. Provide a C++ code segment that illustrates the use of these mode operators.
Use binary reflected Gray code (RGC) to determine how a 16-node linear array can be mapped to a 4-D hypercube. You must derive the 4-bit Gray codes and the corresponding node labels of a 4-D hypercube. Draw the mapping of the 16-node linear array ..
