In C++ Find the five errors. For each error, state the line number, explain the error and show a correction. #include<iostream> #include<iomanip> using namespace std; class colorCode { public: void setRGB(int); //accepts an int parameter and sets the RGB to the value of the parameter void setName(string);//accepts a string parameter and sets the name of the object to the value of the parameter string getName() const;//returns the name of the object int getRGB() const;//returns the RGB of the object void changeColor();// adds 10 to the RGB value private: string name; int RGB; } int main() { colorCode paintCans[10]; int i; for (i = 0; i < 10; i++){ paintCans.setRGB[i] = 0;} paintCans[5].setName(GREEN); paintCan[5].setRGB(192000); cout << paintCans[5].getName << ' ' << paintCans[5].getRGB() << endl; return 0; }
In C++, a reference variable is a variable type that refers to another variable. Example: “int& maxValRef” declares a reference to a variable of type int.

C++ Here is the original question for what it is worth. Please do not give me an answer you found on Chegg. I have one of those accounts too. Please read carefully, I have submitted this question several times and no one could follow directtions. I have my code doing what is asked of the problem with the exception of displaying the last_name, first_name A teacher is requiring her students to line up in alphabetical order, according to their first names..For example, in one class Chapel, Christine would be at the front and Uhura, Nyota would be last. The program will get the names from a file using getline since the file name includes spaces. The names should be read in until there is no more data to read. The program should prompt the user for the file name and read the data from the file. Note that these names might include spaces; handle your input accordingly. The expected output is two names; do not show the entire file. Do not use arrays or sorting for this problem. Here is my…

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…
Question: In C#, how can I recreate this into a Windows form Application instead of a console application? Please show a photo of the display and show the code that you used, thank you! Problem: Write a function Seperate( number ) that separates an integer number (ranging from 0 to 99999) into its digits. For example, if the number is 42329, the function finds 4, 2, 3, 2, 9. If the number is 323, the function finds 0, 0, 3, 2, 3. (Hint: use modulus and integer division operations.) Code: using System;public class RecExercise4{static void Main(){Console.Write("Input any number (ranging from 0 to 99999) : ");int num = Convert.ToInt32(Console.ReadLine());Console.Write(" The digits in the number are : ");separateDigits(num);} static void separateDigits(int n){int i = 4;int[] arr;arr = new int[5];while (i>-1){arr[i] = n%10;n = n/10;i--;}foreach(int j in arr)Console.Write(" " + j);}}
please created a c++ code regarding this screenshot i add and also please add professional comments in it using the // command
I need this done in C++ please! This program implements the top-level menu option 'R' of the Airport Application and constitutes Part 2 of the Airport Application Project requirement. When the user selects 'R' in the airport application, she will be taken to the "page" that is displayed by this program. This program is meant to replace the flight status report program (Programming Assignment 3) that did not use arrays to store the flight status information. It also reads the information from the file token wise.
For C++ I am kinda suck for this part and for pseudocode tooAssume that you have a file that contains the weekly average prices for a gallon of gas in the United States for the past 3 years. The data is stored in the file as records. Each record contains the average price of a gallon of gas on a specific date. Each record contains the following fields: The month, stored as an integer. January = 1, February = 2, etc. The day of the month, stored as an integer. The year, stored as an integer. The average price of a gallon of gas on the specified date, stored as a real number, rounded to 3 decimal places. Design a program that reads the file and displays the lowest and highest gas prices, as well as the dates for those prices.
please code in pythonRead in and return a list of review dates. The function should ask the user to enter some review dates This should be entered in the format mm/dd/yyyy (same as that in the file) where dd is two-digit day, mm is two digit month and yyyy is a four digit year e.g. 01/22/2020 The function should return a list containing the specified review dates. :return: a list of review datesYou can take any review date as sample example
This assignment will give you a chance to perform some simple tasks with pointers. The tasks are only loosely related to each other. Start the assignment by copying the code below and pasting it into a .cpp file, then add statements to accomplish each of the tasks listed. Don't delete any of the given code or comments. Some of the tasks will only require a single C++ statement, others will require more than one. No documentation is required for this part of the assignment. /* Type your code after each of the commented instructions below (except that the statements for instructions 11 and 21 should be written where the instructions indicate). I have written the first statement for you. */ #include <iostream> using namespace std; int main() { // 1. Create two integer variables named x and y. int x; // 2. Create an int pointer named p1. // 3. Store the address of x in p1. // 4. Use only p1 (not x) to set the value of x to 99. // 5. Using cout and x (not p1), display the value of x.…
