    Smile setw not declared in this scope

    Hello I'm having an issue with my code when trying to manipulate my output. My program consists of main.cpp, StudentType.cpp, and StudentType.h. My problem is occuring in StudentType.cpp in this section:

    Code:
    void StudentType::printData(std::ostream& out){
      out << setw(15) << name;
      for (int i=0; i<NUM_GRADES; ++i){
        out << setw(3) << grades[i];
      }
      out << setw(5) << fixed << setprecision(2) << average << std::endl;
    }
    I thought including iomanip would fix it but it did not. I tried to include it in main and in StudentType.cpp and still get the error "setw is not declared in this scope". Any help would be very much appreciated.

    setw is in namespace std.
    Right 98% of the time, and don't care about the other 3%.

    I changed it so that it says std::setw and it gives me the error "setw is not a member of std"

    Ah, I needed to include iomanip and also put std::, I kept doing one or the other. Thank you, it's working now.
