Why isn't my loop program working?

I don't know why my program isn't working. When I compile the program the command prompt is literally blank. Not even the "Press any button to continue..." pops up. The assignment is to create a shipping manifest that reads data from a file and determines a shipping fee and keeps track of the total packages, weight, and charges of the packages. Here is my code:

			t3weight = (t3weight + weight);
			t3profit = (t3profit + price);
		}

	}
	inData >> weight >> code;

	cout << "The total number of packages on Truck 1 is " << t1total << "." << "Amassing a total weight of " << t1weight << "." << "Making a total profit of " << t1profit << "." << endl;
	cout << "The total number of packages on Truck 2 is " << t2total << "." << "Amassing a total weight of " << t2weight << "." << "Making a total profit of " << t2profit << "." << endl;
	cout << "The total number of packages on Truck 3 is " << t3total << "." << "Amassing a total weight of " << t3weight << "." << "Making a total profit of " << t3profit << "." << endl;


	return 0;

When I compile the program the command prompt is literally blank.

See line 15. The program is waiting for your input.

Man do I feel dumb. That was the most simple solution ever. Thanks xD

A general good tip is that you should always, ALWAYS prompt for input. There are situations where you'll just want to keep entering data after the first prompt, but again, there's still a prompt. It doesn't even have to be a long, drawn-out question, it could literally be like:
std::cout << "Weight? : ";

Cout statements in certain places also help with debugging code once you get deep enough.

what's this for?

It's for my C++ class in college.

i meant if you input a few numbers, what should the output be? *If it works correctly*
