2. Write a program that maintains a database containing data, such as name and birthday, about your friends and relatives. You should be able to enter, remove, modify, or search this data. Initially, you can assume that the names are unique. The program should be able to save the data in a file for use later. Design a class to represent the database and another class to represent the people. Use a binary search tree of people as a data member of the database class. You can enhance this problem by adding an operation that lists everyone who satisfies a given criterion. For example, you could list people born in a given month. You should also be able to list everyone in the database.

Write a C++ function (along with helper functions if required) that takes a file stream as a parameter and prints out the maximum negative number in the given file. Do not need to write the main function. An example: [Example file contents] 4 -2 8 12 -8 9 3Prints: Maximum Negative number -2
Draw these on the given diagram: Associations (aggregations/compositions if needed) with names and multiplicities, generalization, attributes (withvisibility and attribute types).
Please complete this program in C++ Please enusre that there is plenty of comments. PLENTY even if unessessary. Please include screenshots of actual code, screenshots of output, and code in the browser so I can copy and paste. Thank you.
The goal for this question: DISCLAIMER****** CODE MUST BE WRITTEN IN C CODE. NOT C++, C#, etc. To create a program that MUST utilize the functions (argc, argv, char strstr, and possibly even Getline) to, 1. Open a file 2. Read the file 3. Read txt file line by line 4. count up the number of times a specified word is read(HOWEVER! IT CANNOT COUNT MORE THAN ONE WORD PER LINE!) ex. if the code comes across a line in a text file that has the word cookie in it 3 times. It can only count the word ONCE since it is counting line by line. Not all the words added up. 5. then display to the user the total number of lines with the specific word. ex. gcc -o <program name> ./<program name> <file name.txt> <"word to be searched"> then execute a total number of times words came up. Again, only count up by one even if there is that specified word multiple times in one line.
FileAttributes.c 1. Create a new C source code file named FileAttributes.c preprocessor 2. Include the following C libraries a. stdio.h b. stdlib.h c. time.h d. string.h e. dirent.h f. sys/stat.h 3. Function prototype for function printAttributes() main() 4. Write the main function to do the following a. Return type int b. Empty parameter list c. Declare a variable of data type struct stat to store the attribute structure (i.e. statBuff) d. Declare a variable of data type int to store an error code (i.e. err) e. Declare a variable of data type struct dirent as a pointer (i.e. de) f. Declare a variable of data type DIR as a pointer set equal to function call opendir() passing explicit text “.” as an argument to indicate the current directory (i.e. dr) g. If the DIR variable is equal to NULL do the following i. Output to the…
- In C++ using Visual Studio - Seperate the files if there is any .cpp, .main or .h files. PART 1Read the contents of the text file and store them in a C++ data structure called std::map<string, int>This map is a collection of sorted <key, value> pairsIn this case, the keys are unique words found in the text file, and the values represent the number of times each word appearsFor example, since the word "cat" appears twice in the file, then map["cat"] = 2 PART 2Iterate through the map and print each key in the order they appearThis will give you a sorted list of unique wordsHere's the expected result: "a big cat does everything feeding goats helping injured juvenile kangaroos locating missing notorious objects playing quietly reading superb tales upvoting videos with xylophone yielding zebras" PART 3Iterate through the map again, this time printing each associated valueThe values represent how many times each word was found in the text filePay attention to the sequence of…
Write a C++ program to do the following: Read the attached file ("TextFile.txt") and the count the number of times each alphabetic letter is used. Do not count punctuation, whitespace, or numbers. Only count letters a-z. When counting, treat lower and upper case characters the same. Use the attached CPP program as a guide to manage the counting. Use the structure and array provided to maintain counts. See examples in the program. When the all processing is completed, display the total for all letter counts. Example Output Below.: This numbers below are not intended to be accurate. No special formatting required but should be readable. A: 103 B: 15 C: 22... // remaining lettersZ: 4 cpp code: #include "stdafx.h" #include <iostream> using namespace std; struct LetterCount { char letter; int count; }; // declare an array of structure const int MAXLETTERS = 26; LetterCount myLetterCount[MAXLETTERS]; int main() { // initialize - MOVE THIS TO A METHOD for…

pls code in pythonplagiarism: This Boolean function takes two filenames. If any line occurs in both files, return True.If not, return False. I suggest using nested loops. With nested loops, we call the loop that is in thebody of the other loop, the "inner loop". The loop that contains the inner loop is the "outer loop". Openthe second file inside the outer loop:for line1 in file1:file2 = open(fname2)for line2 in file2:Python only lets you read the file once per open, so you need this order of instructions. Make sure yourreturn False is outside of both loops. Otherwise, you will only compare the first two lines of thefiles. Make sure you close the file that gets read repeatedly after the inner loop but still inside the outerloop.Here is some (more complete) pseudocode to get you started:open file 1for line1 in file 1open file 2for line2 in file 2:if line1 == line2:return Trueclose file 2return False
