Hey so this is my first ever post so I hope I am doing it right. I have been working on this homework assignment for over a week and I am so close to being done but I cannot figure out the rest. So any help would be great, and please remember I am new to C++ so this assignment might seem easy to you but it is hard for me.

Assignment: Write a C++ program that computes the value of a simple arithmeitc expression consisting of two operands (whose respective values can be either 0, 1 or 2) along with one of the standard arithmetic operators (such as +, -, * and /). Your program should input the operands along with the operator as strings.

my code so far is

I can make everything work but only if they type in 0, 1 or 2. I need to make it work when they type in zero ,one or two. But if I use the string for the number, I cannot use the string in my equation. So basically how can I convert my string into the equation the program should run like this:Code:`#include <iostream>`

#include <string>

using namespace std;

int main()

{

string sign, firstnumber, secondnumber;

float value;

int number1, number2;

// Ask user for numbers and operator

cout << "Please enter the first number(zero, one or two): " << endl;

cin >> firstnumber;

cout << "Please enter operator(plus, minus, divide, times): " << endl;

cin >> sign;

cout << "Please enter the second number(zero, one or two): " << endl;

cin >> secondnumber;

// Solve the expression

if(sign=="plus")

{

value = float(number1 + number2);

if (value > 2)

cout << "The expression you entered is not valid." << endl;

else

cout << "The value of the expression you entered is " << value << "." << endl;

}

else if(sign=="minus")

{

value = float(number1 - number);

if (value > 2)

cout << "The expression you entered is not valid." << endl;

else

cout << "The value of the expression you entered is " << value << "." << endl;

}

else if(sign=="times")

{

value = float(number1 * number2);

if (value > 2)

cout << "The expression you entered is not valid." << endl;

else

cout << "The value of the expression you entered is " << value << "." << endl;

}

if(sign=="divide")

{

value = float(number1 / number2);

if (value > 2)

cout << "The expression you entered is not valid." << endl;

else

if (value == 0)

cout << "Error cannot divide by zero." << endl;

else

cout << "The value of the expression you entered is " << value << "." << endl;

}

return 0;

}

Enter the first operand (zero, one or two):

zero

Enter an arithmetic operator (plus, minus, times, divide):

times

Enter the second operand (zero, one or two):

one

The value of the expression is 0.
