    Perhaps you mean to ask how to convert a char* to a std::string? If that's the case, then you would use the std::string constructor that accepts a const char*

If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    Thanks for your help!

    I've just found a way. I use a temporary string "dept", and it works!

    getline(in, data[count]);
    dept = data[count];
    department = dept[0];
    out << department << endl;
    count++;

    getline() accepts C++ style strings, so that is a lot of extra work you are going through .

    Actually, it looks like thiago_j is using the string version of getline.

    Regardless, there is no need for a temporary string there. data[count][0] is the same as your use of dept. You can use out << data[count][0] << endl.

    You don't need a (named) temporary string.
    Code:
    a_function_that_requires_a_string(std::string(a_char_array));
