Finding highest and lowest values in a string

I am supposed to write a program that lets the user enter random numbers from the keyboard into a string and then the program should total all the numbers and output the total for instance if a user enters 1,2,3,4,5 then it would display the total as "15". I have it to where its correctly displaying the total of the numbers entered but I'm also supposed to display the maximum and minimum digits entered. I can't get this to work correctly because I don't know how to get it to only scan the entered numbers in the string, not the entire randomized string. Here is my code ... thanks in advance for any help!

int main()

    char numbers[100];
    int total = 0, minimum, maximum;


    std::cout << "Enter a series of numbers in a row " << std::endl;
    std::cin >> numbers;

    for (int i = 0; i < strlen(numbers); i++)
    {
        total += numbers[i] - '0';

        for (int i = 0; i < strlen(numbers); i++)
        {

            minimum = numbers[0];
            maximum = numbers[0];


            if(numbers[i] < minimum)
                minimum = numbers[i];

            if(numbers[i] > maximum)
                maximum = numbers[i];

        }

    }
    std::cout << "The total is: " << total << std::endl;
    std::cout << "The maximum number is: " << maximum << std::endl;
    std::cout << "The minimum number is: " << minimum << std::endl;
}

When I compile and run the code you gave me it still outputs this:
(when i enter 1,2,3,4,5)

The total is: 15
The maximum number is: 53
The minimum number is: 49

My guess is that it's scanning the entire array and there are random numbers initialized to it since the user didn't enter all 100 spots themselves.

True, you need to count how many numbers the user enters.
