It works without my loop but when I try to incorporate the loop it wont run.

Anyone know where I'm messing up?

I mainly want to type in 2 numbers and have it spit out the sum. Then I want it to reset and start over so I can do 2 more new numbers.

{

	for (i = 1; i < 1000; i++)
	{

	cin >> a;
	cin >> b;

	sum = a + b;
	cout << sum;
	cout << "\n\n\n\n"
	}

Hey Irhcsa,

I looked your code over and I noticed two things.

Your loop control variable (i) is undefined.

for (int i = 1; i < 1000; i++)

The second mistake I noticed, is you are missing a semi-colon after your last cout statement.

cout << "\n\n\n\n";


I hope this helps you out, Irhcsa.

Happy coding

your code is fine, but you use a variable for iteration that hasn't been declared yet.

for (i = 1; i < 1000; i++) this should be for ( int i = 1; i < 1000; i++ )

Alright I have another hick up.

My program runs and I can do addition and subtraction just fine but the multiplication and division don't seem to be wanting to work. I have searched online and am sure that the correct characters are * and / Here's what I have so far.

The program runs, but when entering a division problem for example, the program does some weird beeping and a ton of stuff flashes and it crashes.

¿where are you reading the operator?

In the if statement. It works for addition and subtraction.
