In C++ and using command line arguments, how do you check if an argument is a double or integer?

C++ Create a program that reads a simple arithmetic expression and evaluates it. More precisely, the program reads from the user a line of text that’s supposed to contain two numbers separated by an arithmeticoperator, as in: 35.6 + 12 The program then prints back the expression and its value, as in: 35.6 + 12 = 47.6 The program should verify that the input line contains two numbers, one operator and nothing else. There can be whitespace before the first number, after the second number and between each number and the operator.The operator can be either +, −, *, or /. In case of an error, the program should print: "Invalid expression" and quit.When the program prints the expression, there should be no whitespacebefore the first number and there should be exactly one blank space beforeand after the operator and the equal sign.Use string streams.

A legal C++ declaration and initialization is: Question options: grade1 = 67.0; float grade1 = 67.0; float grade2 = float grade1; float grade1, grade2;

I need your help with the question attached, Your writing your program in C# . When writing or printing out the output of your code please use the format when writing your code and when you want to print out the data too static void Main(string[] args) { int student_id; int student_pass, highest_avgerage_id, student_fail; student_pass = 0; student_fail = 0; highest_avgerage_id = 0; Console.Write("Enter a student id (0 to quit): "); student_id = Convert.ToInt32(Console.ReadLine()); Console.WriteLine("Number of student who are moving on: " + student_pass); Console.WriteLine("Number of student who are not moving on: " + student_fail); if (student_id == 0) { is_continue = false; break; } This is the format I need any tutor working on this to use when they are solving the problem and writing the code in C# please. Please let me know if...

Variables that are declared outside the body of any function are called what? in C

In C++: Print a table that prompts the user to enter the current tuition and displays a table that displayshow many years the tuition will be doubled if the tuition is increased by 5%, 6%, and up to 10%annually. Here is a sample run: Enter the current year tuition: 20000 Rate Number of Years 5.0% 15 6.0% 12 7.0% 11 8.0% 10 9.0% 9 10.0% 8 1. Add comments throughout the program explaining your code.2. Use meaningful names for variable names.3. Submit program in .cpp file

A pair of primes that vary by two is a pair of twin primes (e.g., 3 and 5, 101 and 103). Write a C++ application that displays the total number of twin primes smaller than 1000.

In C++, Given the following mystery function, what is the output if the number passed to the function is 7: int mystery(int number) { if (number == 0 || number == 1) return number; else return mystery(number - 1) + mystery(number - 2); }

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);}}

C++ with multiple functions if possible Write a program to simulate an automated teller machine (ATM) at a bank. The program should ask the user for a four-digit personal identification number (PIN) to verify they are supposed to have access to the account. If they enter the PIN incorrectly, they should be denied access to the account, but the program should automatically ask them to enter the PIN again. It is up to you to decide if you want to give a maximum number of tries before exiting. The ATM program should ask the user for a beginning balance, and then provide the user with the opportunity to enter deposits and withdrawals until the user wishes to exit the program. Upon exiting the program, it needs to display the current balance.

In C++ Programming, write a program that calculates and prints the monthly paycheck for an employee. The net pay is calculated after taking the following deductions: Federal Income Tax: 15% State Tax: 3.5% Social Security Tax: 5.75% Medicare/Medicaid Tax: 2.75% Pension Plan: 5% Health Insurance: 75ドル.00 Your program should prompt the user to input the gross amount and the employee name. The output will be stored in a file. Format your output to have two decimal places. A sample output follows: Bill Robinson Gross Amount: .......................... 3575ドル.00 Federal Tax: ................................ $ 536.25 State Tax: .....................................$ 125.13 Social Security Tax: ................... $ 205.56 Medicare/Medicaid Tax: ......... $ 98.31 Pension Plan: .............................. $ 178.75 Health Insurance: .......................$ 75.00 Net Pay: ....................................... 2356ドル.00 NOTE: The first column is left-justified, and the right column is...
