another array exercise

Hi.. I have another array exercise and it has this debug error again but this time it doesn't give the sum output.

The code is as follows:

Code:

---

//array initialization and sum output based on user input

#include <iostream>
using namespace std;

int main ()
{
        int ar[7] = {ar[0], ar[1], ar[2], ar[3], ar[4], ar[5], ar[6]};
        int sumArray = 0;
        int i = 0;

        cout << "Enter an integer for value 1: ";
        cin >> ar[0];
        cout << "Enter an integer for value 2: ";
        cin >> ar[1];
        cout << "Enter an integer for value 3: ";
        cin >> ar[2];
        cout << "Enter an integer for value 4: ";
        cin >> ar[3];
        cout << "Enter an integer for value 5: ";
        cin >> ar[4];
        cout << "Enter an integer for value 6: ";
        cin >> ar[5];
        cout << "Enter an integer for value 7: ";
        cin >> ar[6];

                for (i = 0; i < 7; i++);
        {
                sumArray += ar[i];
        }
        cout << endl;
        cout << "Total is: ";
        cout << sumArray << endl;
}

Any ideas will be great! Thanks..

Code:

int ar[7] = {ar[0], ar[1], ar[2], ar[3], ar[4], ar[5], ar[6]};

In some languages, this doesn't even compile, and for good reason. Just what do you think this should achieve?

Code:

---

for (i = 0; i < 7; i++);
{
    sumArray += ar[i];
}

The semicolon at the end of the for loop is wrong.

Try:

Code:

---

#include <iostream>
using namespace std;

int main ()
{
    int ar[7];
    int sumArray = 0;
    int i;

    for (i = 0; i < 7; i++)
    {
        cout << "Enter an integer for value " << i+1 << ": ";
        cin >> ar[i];
        sumArray += ar[i];
    }

    cout << endl << "Total is: " << sumArray << endl;

}

Or even, since you don't ever use the array:

Code:

---

#include <iostream>
using namespace std;

int main ()
{
    int sum = 0;

    for (int i = 0; i < 7; i++)
    {
        cout << "Enter an integer for value " << i+1 << ": ";
        int tmp;
        cin >> tmp;
        sum += tmp;
    }

    cout << endl << "Total is: " << sum << endl;

}

Thanks CornedBee and hk for pointing out my mistakes..

It's working fine now.. I chose to stick with the array since it's an array exercise although CornedBee's program also works!

Code:

---

//array initialization and sum output based on user input

#include <iostream>
using namespace std;

int main ()
{
       
        int ar[7];
        int sumArray = 0;
        int i = 0;

                for (i = 0; i < 7; i++)
        {
            cout << "Enter an value for " << i + 1 << " : ";
                cin >> ar[i];
                sumArray += ar[i];
        }
        cout << endl;
        cout << "Total is: ";
        cout << sumArray << endl;
}

Again, thanks for the help, guys!!
