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];
}

Answer:

20 files.

Explanation:

Given the following data;

Size of file = 100 kilobytes.

Folder size (memory) = 2 megabytes.

Method 1

1000 kilobytes = 1 megabytes.

100 kilobytes  = x megabytes

Cross-multiplying, we have;

1000x = 100

x = 100/1000

x = 0.1 mb

Now, to find the number of files that can be stored;

[tex] Number \; of \; files = \frac {Memory}{Size \; of \; each \; file} [/tex]

Substituting into the equation, we have;

[tex] Number \; of \; files = \frac {2}{0.1} [/tex]

Number of files = 20 files.

Method II

We know that;

Substituting into the formula, we have;

[tex] Number \; of \; files = \frac {Memory}{Size \; of \; each \; file} [/tex]

Substituting into the equation, we have;

[tex] Number \; of \; files = \frac {2000}{100} [/tex]

Number of files = 20 files.

Answer:

In Latin America and the European Union, for example, 12 and 37 percent of health workers are public sector employees, respectively. Hence wage increases may reduce funding available for other critical medical supplies and equipment, particularly in developing countries with limited fiscal resources. Wage increases for one category of workers, however well justified, can also trigger demands from other workers, particularly in countries with strong trade unions. Temporary salary increases or supplementary payments also tend to become permanent, thereby creating long-term distortions and problems of fiscal sustainability. The first step, then, is to quickly assess the level and structure of health worker compensation to quantify the amount of additional wages that should be paid. Health facility staff consists of frontline medical staff (doctors, nurses, community health workers) as well as non-medical administrative and support staff. In many World Bank client countries, the total gross wages of health workers will consist of:

1.Basic salary. This is based on pay grades in civil service pay laws, or wage legislation for public health workers.

2.Overtime allowance or compensation for overtime work. This is usually in the form of a percentage of basic pay for additional hours worked beyond what is normally specified.

3.Hazard allowance or harmful work conditions allowance. These will be allowances as a percentage of pay for working conditions that are considered risky to the individual.

Other allowances.

4.Other allowances. These typically factor in seniority, additional training, or educational qualifications, as well as working in rural areas or remote locations

5.Performance pay. These are additional payments conditional on either inputs (e.g., working hours), outputs (e.g., patients treated), or outcomes (e.g., patient satisfaction).

6.Per diems or salary supplements. These are usually for attending workshops or training and can be a significant (more than 10 percent) proportion of gross wages.

Cross-national data on health worker wages is very limited. The data that the World Bank has for 10 countries in Latin America and 27 in the European Union shows that while health care workers do enjoy a premium over workers in other sectors of the economy, the premium decreases with country income levels. For countries in the upper income category, they experience a penalty compared to similar workers in lower-income countries (controlling for sex, education, and location). These averages, however, hide variations across different categories of health workers (medical workers represent between 20 and 50 percent of all health care sector workers for countries in Latin America and the European Union).

The credit limit on your credit card is the most you are permitted to spend.

Your credit limit won't be disclosed to you until the card you requested for is authorized. Applying for a secured credit card, where your security deposit frequently matches your credit limit, is an exception to this rule.

Also keep in mind that your credit limit is a real, set amount that you must adhere to.

You might be given the option to opt in and go beyond your limit, but only if you pay a cost. I strongly advise against signing up since it will be like having overdraft protection on your credit card. It leads inevitably to significant debt.

Therefore, The credit limit on your credit card is the most you are permitted to spend.

t2 = g2 * a;//using the t1 variable to calculate tensions

printf("\nResulting tension on cable #2: %.2f Newtons", t2);//print tension value

printf("\n-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-");//use print method for design

return 0;

}

Output:

Please find the attached file.

Explanation:

In this code four integer variable "plane, g1, g2, and f" and four floating-point variables "m, a, t1, and t2" is declared, in which the integer variable is used for input the value from the user-end.

In the next step, the "m" variable is used, which adds the "plane, g1, and g2" integer value to calculate mass, and in the "a" variable it calculates the acceleration, and in the "t1 and t2" variable it calculates the tension and prints its value.

Answer:

#include<iostream>

using namespace std;

int CountCharacters(char userChar, const string inputstr){

   int k = 0;

   int iter = 0;

   for (iter = 0; iter < inputstr.size(); iter++){

       if (inputstr[iter] ==  userChar){

           ++k;        }}

   return k;}

int main(){

   string str;

   char userChar[1];

   cout<<"Char: ";    cin>>userChar;

   cin.ignore();

   cout<<"String: ";   getline(cin, str);

   cout<<CountCharacters(userChar[0],str);

   return 0;}

Explanation:

Written in C++:

The function is defined here:

int CountCharacters(char userChar, const string inputstr){

This initializes a count variable k to 0

   int k = 0;

This initializes an iterating variable iter to 0

   int iter = 0;

This iterates through the characters of the string being passed to the function

   for (iter = 0; iter < inputstr.size(); iter++){

This checks for matching characters

       if (inputstr[iter] ==  userChar){

If found,  k is incremented by 1

           ++k;        }}

This returns the total count

   return k;}

The main begins here

int main(){

This declares a string variable

   string str;

This declares a character variable

   char userChar[1];

This gets input for the character variable

   cout<<"Char: ";    cin>>userChar;

This lets the user get another input

   cin.ignore();

This gets input for the string variable

   cout<<"String: ";   getline(cin, str);

This calls the function and return the count of character in the string

   cout<<CountCharacters(userChar[0],str);

Answer:

In C++:

#include<iostream>

#include<vector>

using namespace std;

int main() {

int len;

cout<<"Length: ";  cin>>len;

string inpt;

vector<string> vect;

for(int i =0;i<len;i++){

   cin>>inpt;

   vect.push_back(inpt); }

char ch;

cout<<"Input char: ";  cin>>ch;  

for(int i =0;i<len;i++){

   size_t found = vect.at(i).find(ch);  

       if (found != string::npos){

           cout<<vect.at(i)<<" ";

           i++;

       }

}  

return 0;

}

Explanation:

This declares the length of vector as integer

int len;

This prompts the user for length

cout<<"Length: ";  cin>>len;

This declares input as string

string inpt;

This declares string vector

vector<string> vect;

The following iteration gets input into the vector

for(int i =0;i<len;i++){

   cin>>inpt;

   vect.push_back(inpt); }

This declares ch as character

char ch;

This prompts the user for character

cout<<"Input char: ";  cin>>ch;  

The following iterates through the vector

for(int i =0;i<len;i++){

This checks if vector element contains the character

   size_t found = vect.at(i).find(ch);  

If found:

       if (found != string::npos){

Print out the vector element

           cout<<vect.at(i)<<" ";

And move to the next vector element

           i++;

       }

}  

Following are the solution to the given question:

Program Explanation:

Program:

#include <iostream>//header file

#include <string>//header file

   vector<string> x;//defining vector array of string

   int n1,i,j;//defining integer variable

   string w;//defining string variable

   char c;//defining character array

   cin >> n1;//input integer value

   for (i = 0; i < n1; ++i)//defining loop that inputs string value from user-end

   {

       cin >> w;//input value

       x.push_back(w);//using push_back method that add value in vector array

   }

   cin >> c;//input character value

   for (i = 0; i < n1; ++i)//defining loop that match value

   {

       bool f = false;//holding boolean value

       for (j = 0; j < x[i].size(); ++j) //defining loop that check array value with character value

       {

           if (x[i][j] == c)//defining if block that check array value with character value

               f= true;//holding boolean value

       }

       if (f)//defining if block that check boolean value

       {

           cout <<x[i] << endl;//print value

Square capitals were used to write inscriptions, and less often to supplement everyday handwriting. When written in documents this style is known as Latin book hand. For everyday writing the Romans used a current cursive hand known as Latin cursive. Notable examples of square capitals used for inscriptions are found on the Roman Pantheon, Trajan's Column, and the Arch of Titus, all in Rome. Square capitals are characterized by sharp, straight lines, supple curves, thick and thin strokes, angled stressing and incised serifs. These Roman capitals are also called majuscules, as a counterpart to minuscule letters such as Merovingian and Carolingian.
