Equation printing program

[socondc22]

So i have a question on how i should start doing this... pretty new at c++

i have to ask the user for an integer, an operator, and then another integer to give an answer. But i also have to show the whole equation. I want to try to use loops to do this.

Im using a do while loop to try to rerun my program at the end so that itll ask me to type y in order to rerun... everytime i type y and hit enter it exits the program... any ideas??

Can you show us how have you implemented this do while loop?

i used

char rerun_choice = 'c';

do
            {
              MY CODE
            }
               while (rerun_choice == 'y');
               cout<<"run again type y"<<".\n";
               cin>> rerun_choice;

char rerun_choice = 'c';

do
            {
              MY CODE
            }
               while (rerun_choice == 'y');
               cout<<"run again type y"<<".\n";
               cin>> rerun_choice;
 
 

Shouldn't that be inside the loop?

do{
        YOUR CODE
 
         cout<<"To run again type y"<<endl;
         cin>> rerun_choice;
 
}while(rerun_choice=='Y')

Also you should convert user input to upper letters(what if user inputed y?)
You can use toupper(),defined in ctype.h

it says expected identifier before ")" token for this part...

else if ((operator) = "/")

You shouldn't need the second set of parenthesis and you need the double equal sign ('==')

if (operator == "+"){}
else if (operator == "/"){}

Your variable, "operator", is of type char. This means you might need to use a single quote rather than double quotes as follows:

if (operator == '+')
    cout<<"The Answer is: "<< x << "+" << y << "=" << x + y <<endl;
 
 
else if (operator == '-')
    cout<<"The Answer is: "<< x << "-" << y << "=" << x - y <<endl;
 
 
else if (operator = '*')
    cout<<"The Answer is: "<< x << "*" << y << "=" << x * y <<endl;
 
else if (operator = '/')
{
    cout<<"The Answer is: "<< x << "/" << y << "=" << x / y <<endl;
    cout<<"The Remainder is: "<< x << "%" << y << "=" << x % y <<endl;
}
 
else
    cout<<"Bad operator input, try again..."<<endl;

Yep, I missed that, sorry.

Any ideas on what i should do because i need to try to get it done for tomorrow?

After you made the assignment, what error messages did you get?

And this is an example of why we ask people to not double post.

Socondc22 - please read our Posting Guidelines and follow them in the future (not double-posting). Thanks.

instead of asking to continue its just rerunning the program... im not sure if i have everything placed right...

And this is another example of why you shouldn't double (triple) post. Did you take Savage's advice in your other thread and put the prompt inside the do-while loop?

AGH!

USE A DIFFERENT NAME FOR YOUR CHAR VARIABLE.

Sorry, I can't believe no one's caught this yet. You can't use operator as the name of your char variable, because operator== is a function call for classes. Your compiler thinks you are calling the function operator== in every if statement, and then complains at the fact that there's no object, no parentheses, and no argument. Change the name to oper and see if it works.

It was caught (or at least different) in his other thread. There are three floating around now, I haven't gotten around to cleaning them all up.

I'm not sure if this is the 3rd or 4th time you've asked for help on this question, but before you proceed any further, could you take a good look at our Posting Guidelines, specifically the portion entitled Do Not Double Post your Questions.

Yes AGH!!!
I thought about that the name might be the problem at least 5 times but I couldn't figure out why so I always ignored it.

P.S. The O/P made it really confusing with double posting.
