    Do you mean tokenize the string? Break it into parts where it's separated by a certain character?

    Cut the string? You mean make substring from a given string? Use the substr member function.

    Code:
    string str = "Hello World";
    cout << str.substr(6) << endl;   // Outputs "World"
    cout << str.substr(6,2) << endl; // Outputs "Wo"
    cout << str.substr(0,5) << endl; // Outputs "Hello"
    [edit]Please clarify what you mean by "cut".[/edit]

    You can refer to individual characters in the array.

    Code:
    char array[30];
    array[0] = 'A'; // first character
    array[1] = 'B'; // second character, etc...

    Do this, write out an example of what exactly you want to do.

    hk_mp5kpdw already gave an example of how to pull substrings out.

    I doubt anyone's going to write a complete program for you, because this sounds a lot like a homework assignment. You could just run your string through a loop that performed a switch/case statement on each element. If it was a number, add that number to a running total. If it was a null character, exit out of the loop.
