Reading in a file in C++

[Amulon]

I am trying to read in a file that is similar to this:

push 10
pop
push 20
push 30
pop
push 10
push 50
push 20
push 20
pop

I am trying to make it so if it says push then it uses the pushfunction to push 10. And when it says pop it will pop off the top of the stack. Etc...

When you read in a file how do you make it read in the string, then use the integer?

	getline(cin, fileAddress);
	ifstream textFile (fileAddress);

	//Tests the file
	if (textFile.fail())
	{
		cout << "File was not found"<< endl;
		system("PAUSE");
		exit (1);
	}
	else
		cout << "\nFile opened successfully" << endl;

That is what I have to read in the code but I am just stuck on how to store it then use it.

Thanks for the help!

So you are saying that with each line of file that I read I should do a line of code like:

data >> stringVariable >> intVariable

Yes, something like that. Providing of course that 'data' is a non-blocking stream.

For example:

fstream file("data.txt", fstream::in);

if (file)
{
    while (!file.eof())
    {
        string data;

        getline(file, data);

        if (file)
        {
            istringstream iss(data);
            string op;
            int value;  

            iss >> op >> value;


            // ...
        }
    }
}

So I have used your insights to pretty much finish the project. Everything is good until 1 spot. The file is like:

push 10
push 10
push 10
push 10
pop
push 2
push 2
push 2

And when it doesnt read any data (other than the string) on the pop line, then the whole things gets screwed up. What hints/tips do you have to get this fixed?

Whose insights? (Your own?)

"Screwed up", etc -- what do these mean??

Keep in mind, that sensible people reading this post are not here to complete your assignment. Show us what you have thus far attempted.

Uh... ? Why would I say that thanks for using my own insights? Of course I mean't the people who helped me.

I am not mad/frustrated in the slightest about what people have replied. I am not saying that the people who helped me screwed up, I am saying that there is another problem I have discovered with my own code and I need some help with this.

It is the weekend; I do not have the luxury of depending on my crystal ball to get insight into the current state of your code.

Perhaps if you posted it (that is, the code), along with the problem you are experiencing, I, or someone else, may be able to help you.

Man, stop complaining.

Man, stop complaining.

You just sealed your fate.
