Write a program using integers userNum and divNum as input, and output userNum divided by divNum three times.

Answer:

Follows are the code to this question:

#include <iostream>//header file

using namespace std;

int main() //defining main method

{

int userNum, divNum;//defining integer variable

cin>> userNum >> divNum;//input values

cout <<"First-time divide: "<<userNum / divNum<<endl;//divide value First time  

cout <<"Second-time divide: " << userNum / divNum/divNum<<endl; //divide value Second time

cout<<"Third-time divide: "<< userNum /divNum/divNum/divNum<<endl;//divide value Third time

return 0;

}

Output:

2000

2

First-time divide: 1000

Second-time divide: 500

Third-time divide: 250

Explanation:

In this code two integer variable "userNum and divNum" is declared that uses the input method to input value from the user-end, and after input the value it divides the "userNum by divNum" three times, that is defined as follows:

In this code, the user input the value 2000 and 2, in the first divides it will give 1000, in the second time divide it will give 500, and in the third time it will give 250.

Build a class and a driver for use in searching your computer’s secondary storage (hard disk or flash memory) for a specific file from a set of files indicated by a starting path. Lets start by looking at a directory listing. Note that every element is either a file or a directory.
Introduction and Driver
In this assignment, your job is to write a class that searches through a file hierarchy (a tree) for a specified file. Your FindFile class will search a directory (and all subdirectories) for a target file name.
For example, in the file hierarchy pictured above, the file "lesson.css" will be found once in a directory near the root or top-level drive name (e.g. "C:\") . Your FindFile class will start at the path indicated and will search each directory and subdirectory looking for a file match. Consider the following code that could help you build your Driver.java:
String targetFile = "lesson.css";
String pathToSearch ="
C:\\WCWC"; FindFile finder = new FindFile(MAX_NUMBER_OF_FILES_TO_FIND);
Finder.directorySearch(targetFile, pathToSearch);
File Searching
In general, searching can take multiple forms depending on the structure and order of the set to search. If we can make promises about the data (this data is sorted, or deltas vary by no more than 10, etc.), then we can leverage those constraints to perform a more efficient search. Files in a file system are exposed to clients of the operating system and can be organized by filename, file creation date, size, and a number of other properties. We’ll just be interested in the file names here, and we’ll want perform a brute force (i.e., sequential) search of these files looking for a specific file. The way in which we’ll get file information from the operating system will involve no ordering; as a result, a linear search is the best we can do. We’d like to search for a target file given a specified path and return the location of the file, if found. You should sketch out this logic linearly before attempting to tackle it recursively.
FindFile Class Interface
FindFile(int maxFiles): This constructor accepts the maximum number of files to find.
void directorySearch(String target, String dirName): The parameters are the target file name to look for and the directory to start in.
int getCount(): This accessor returns the number of matching files found
String[] getFiles(): This getter returns the array of file locations, up to maxFiles in size.
Requirements
Your program should be recursive.
You should build and submit at least two files: FindFile.java and Driver.java.
Throw an exception (IllegalArgumentException) if the path passed in as the starting directory is not a valid directory.
Throw an exception if you've found the MAX_NUMBER_OF_FILES_TO_FIND and catch and handle this in your main driver. Your program shouldn't crash but rather exit gracefully in the unusual situation that we've discovered the maximum number of files we were interested in, reporting each of the paths where the target files were found.
The only structures you can use in this assignment are basic arrays and your Stack, Queue, or ArrayList from the previous homeworks. Do not use built-in data structures like Java's ArrayList. To accomplish this, put in the following constructor and method to your ArrayList, Stack, or Queue:
public ArrayList(Object[] input) { data = input;
numElements = input.length;
}
public Object get(int index) {
return data[index];
}

In 2019, the tuition for a full time student is $7,180 per semester. The tuition will be going up for the next 7 years at a rate of 3.5% per year. Write your program using a loop that displays the projected semester tuition for the next 7 years. You may NOT hard code each years tuition into your program. Your program should calculate the tuition for each year given the starting tuition in 2019 ($7, 180) and the rate of increase (3.5%). You should then display the actual year (2020, 2021, through 2026) and the tuition amount per semester for that year

Create a text file content.txt and copy-paste following text (taken from Wikipedia) into it: A single-tasking system can only run one program at a time, while a multi-tasking operating system allows more than one program to be running in concurrency. This is achieved by time-sharing, dividing the available processor time between multiple processes that are each interrupted repeatedly in time slices by a taskscheduling subsystem of the operating system. Now, write a C program that opens content.txt file for reading and calls fork() function. The child process in the program will print first 150 characters from the file and the remaining characters will be printed by the parent. However, at the

1. UNIX cat command has three functions with regard to text files: displaying them, combining copies of them and creating new ones.
Write a C program to implement a command called displaycontent that takes a (text) file name as argument and display its contents. Report an appropriate message if the file does not exist or can’t be opened (i.e. the file doesn’t have read permission). You are to use open(), read(), write() and close() system calls.
NOTE: Name your executable file as displaycontent and execute your program as ./displaycontent file_name
2. The cp command copies the source file specified by the SourceFile parameter to the destination file specified by the DestinationFile parameter.
Write a C program that mimics the cp command using open() system call to open source.txt file in read-only mode and copy the contents of it to destination.txt using read() and write() system calls.
3. Repeat part 2 (by writing a new C program) as per the following procedure:
(a) Read the next 100 characters from source.txt, and among characters read, replace each character ’1’ with character ’A’ and all characters are then written in destination.txt
(b) Write characters "XYZ" into file destination.txt
(c) Repeat the previous steps until the end of file source.txt. The last read step may not have 100 characters.

What were Roman Capitals first used for?

The Westfield Carpet Company has asked you to write an application that calculates the price of carpeting for rectangular rooms. To calculate the price, you multiply the area of the floor (width times length) by the price per square foot of carpet. For example, the area of floor that is 12 feet long and 10 feet wide is 120 square feet. To cover that floor with carpet that costs $8 per square foot would cost $960. (12 × 10 × 8 = 960.) First, you should create a class named RoomDimension that has two FeetInches objects as attributes: one for the length of the room and one for the width. (You should use the version of the FeetInches class that you created in Programming Challenge 11 with the addition of a multiply member function. You can use this function to calculate the area of the room.) The RoomDimension class should have a member function that returns the area of the room as a FeetInches object. Next, you should create a RoomCarpet class that has a RoomDimension object as an attribute. It should also have an attribute for the cost of the carpet per square foot. The RoomCarpet class should have a member function that returns the total cost of the carpet. Once you have written these classes, use them in an application that asks the user to enter the dimensions of a room and the price per square foot of the desired carpeting. The application should display the total cost of the carpet.
