Class

Object Oriented Programming System (OOPs) is a programming model built on the perception of “objects” that contains data and methods. The major purpose of Object Oriented Programming is to increase the maintainability and flexibility of programs. Object Oriented Programming gets together data and its behavior (methods) in a single location (object) which makes it easier to understand.

The following question is related to C programming system call Task-1: Write a c program that will open a file given from the command line argument and then it will ask the user to input strings that will be written to that file. It will continue to ask the user to enter a string as long as the user enters “-1”. If the given file does not exist in the directory, then your program will automatically create the file.
Demonstrate an understanding of basic C++ programming concepts by completing the following: Program: Create a simple C++ console application that will write a program that will take string input from a user. Your program should reverse the string and then print the output to the screen. Take input from the user 3 times for varying string lengths. Program Analysis: Given your program implementation, discuss and identify the possible vulnerabilities that may exist. If present, discuss solutions to minimize the vulnerabilities. Then discuss and identify possible problems that can result in errors for string manipulation of data. Your program analysis should be 1-2 pages in length.

Write a C++ program named "PrintOneExpression" that will read in an expression and print out its formatted one with correct result. Objective: - make sure that you can have the C++ environment setup and can write programs with basic C++ input and output Requirements: - keep the expression simple with 2 operands and one operator(+,−,∗and/)- assume that the user will enter a correct expression. There is no need to handle errors in this exercise - all values in the expressions are integers - the output of the expression must be formatted with 5 spaces between each value and operator and must have the correct result of the expression.
The following project should be done in C++ language: Write a function (module) that reads the contents of a file named Char.txt (you will have to create this file on notepad or any other text editor and write a sentence of your choice. Your sentence should include upper case, lower case, and numbers. Keep in mind you need to submit this file as well) and determine the following: The number of uppercase letters in the file . The number of lowercase letters in the file The number of digits in the file The total number of characters in your sentence. Upon finishing the task, program will ask the user if they would like to read the same file again and the program will re-start (you need to utilize a loop to do so) should the user prompt the program with 'Y'. Prompts and Output Labels. There are no prompts-- nothing is read from standard keyboard, just from the file Character.txt. Each of the numbers calculated is displayed on a separate line on standard output, preceded by the following…

Create a standard C++ program wherein it satisfies the following objectives 1.Create a menu. (Under the menu, it should display the following) *Testing *Information *Exit note: create a loop link between the menu and the program will only stop if the user chooses "exit". 2.I will provide the codes under the testing menu and it's up to you if you want to improve it a little further. 3. Under the information menu, the program will then ask the user for its name, address, age, and current relationship status, be creative and you can add small simple features to the program itself. Thanks a lot! Here's our first version program under the testing menu #include <iostream>using namespace std; int main() { bool hasFever; bool hasCough; bool breathingProblem; char input; cout << "WELCOME TO COVID-19 TRACKER \n \n" ; cout << "Does the patient have fever?
