simple loop

[[praetorian]]

Hi!

I've tried to make a program that asks the user to enter 2 numbers and then take the first number and add the coming to that one until you've reached the top number that was entered by the user.

Simple; if the user enters 1 and 5, the program would calculate and add toghether all the numbers between and included the entered numbers (1 & 5).

any ideas?

thanks in advance!

#include <iostream.h>

int main()
{
	int end;
	cout << "End? ";
	cin >> end;
	if (end <= 0)
	{
		cout << "End must be greater than 0" << endl;
		return 1;
	}
	int sum = 0; // important to initialize it!
	for (int i = 1; i <= end; i++)
	{
		sum += i;
	}
	for (i = 1; i <= end)
	{
		cout << i;
		if (i != end)
		{
			cout << " + ";
		}
	}
	cout << " is " << sum;
	return 0;
}

int numaddthing()
{
        int num1, num2, i, res = 0;
        cout << "Enter first number: "; cin >> num1;
        cout << "Enter second number: "; cin >> num2;

        for(i = num1; i <= num2; i++)
        {
                res += i;
        }
        return res;
}
