Input an Array then Find sum of digits and num of digits

[ollie335]

Hi, I've been trying to create a C++ program that gets the input from the user, calculates the amount of digits in the array and then calculates the sum of the digits

Heres what i've got so far

int main()
{
    char num[100];


    cout << "\nEnter Number: ";
    cin >> num;

    int counter = 0;
    for (int i = 0; num[i] != '\0'; i++)
        counter += 1;


    cout << counter << endl;

    int sum = 0;
    for (int a = 0; num[a] != '\0'; a++)
    {     
        num[a] = num[a] = '0';
        sum += num[a];
    }

    cout << sum;

    return 0;
}

but i cant seem to find the sum of the digits

>num[a] = num[a] = '0';
= is not the same as -. One is assignment, the other is subtraction. This is the line you want that will give you the correct sum:

num[a] = num[a] [B][I]-[/I][/B] '0';
