Question

I would like to have a clean formatted output, but the result is not exactly as clean as I want. Below is my function which shows the output, followed by the output. I am using Dev-C++. Thank you for your help.

void student::show(string name, int age, double GPA)
{
  cout<<name<<setw(7) <<age<<setw(7) <<GPA <<setw(7) <<endl;

}

Since setw sets the width for the next output value, not for the previous one, you should move setw calls to before the items being formatted:

cout << setw(20) << name << setw(7) << age << setw(7) << GPA << endl;
