    Code:
    doskey_vector.at(j) = x;
    You may have to use doskey_vector.push_back(x) instead.

    like this?

    Code:
    doskey_vector.at(j) = doskey_vector.push_back(x);
    I want to store the current value of variable x, to the vector. So every time the user types a command, the command will be stored, and the next one and so on...

    Thank you

    No, just use the push_back() member function.

    You may want to read cppreference.com's article on vectors, and also check out SGI's Standard Template Library Programmer's Guide.
