    Depending on length of name, output changes?

    I cannot keep the << firstName << and << lastName << from moving "Grade Points" in the output. I am instructed to keep these in the same line but If I do it varies depending on the name.

    Code:
    // Output Area of Program
    		cout << endl;
    		cout << endl;
    		cout << "                  Class Heading" << endl;
    		cout << "              Date of Report:04/25/2005" << endl;
    		cout << endl;
    		cout << endl;
    		cout << "Student: "<< lastName <<", "<< firstName  <<      "Grade  Points " << endl;
    		cout << endl;
    		cout << endl;
    		cout << "         Exam 1 grade, points:" <<"               "<<exam1<<" "<< endl;
    		cout << "         Exam 2 grade, points:" <<"               "<<exam2<<" "<< endl;
    		cout << "         Exam 3 grade, points:" <<"               "<<exam3<<" "<< endl;
    		cout << "     Final Exam grade, points:" <<"               "<<finalExam<<" "<<endl;
    		cout << "          Lab 1 grade, points:" <<"               "<<lab1<<" "<<endl;
    		cout << "          Lab 2 grade, points:" <<"               "<<lab2<<" "<<endl;
    		cout << "          Lab 3 grade, points:" <<"               "<<lab3<<" "<<endl;
    		cout << "          Lab 4 grade, points:" <<"               "<<lab4<<" "<<endl;
    		cout << endl;
    		cout << "Total Daily Points = " << dayPnts << endl;
    		cout << endl;
    		cout << "Semester Points    = " << semPoints << endl;
    		cout << endl;

    You need to use some formatting commands like setw perhaps.

    Code:
    #include <iomanip>
    using namespace std;
    
    ...
    
    cout << "Student: " << set(20) << lastName << ", " << setw(20) << firstName  << " Grade  Points " << endl;
    Choose something appropriate for the two values based on the number of characters in your lastName and firstName variables.

    I don't think there really is any kind of standard way of keeping "Grade Points" in one location, regardless of how long the string before it is. Instead, why don't you just enter a new line with "Grade Points" only on it? Also, it might help you to know the escape character for entering a tab, '\t'.

    hk_mp5pdw, I tried what you ask and even substituted my line for yours and even included the directive #include <iomanip> but after I compiled it said undelared identifier, What did I do wrong?

    Krak, I want to put it on another line but unfortunately my Instructor insists that it must stay where it belongs. My instructor said that I have to move the insertion or move the " " to get the desired result the he or she asked for. I'm not familiar with '\t' is there a tutorial here that explains this in detail?

    Did you forget the using namespace std; part? What other headers are you including? What compiler are you using? What is the exact error message and the line of code that produces that error message?

    ...
    << set(20) << lastName << ", " << setw(20)
    ....

    There was a typo error after I fixed it in my program it ran ok but I am still having problems with the names moving the "grade" and "points" heading . Even though I change the numeric value the same problem occurs.

    Maybe you want to use the left justified flag:
    Code:
    cout << left << "Student: " << set(20) << lastName << ", " << setw(20) << firstName  << " Grade  Points " << endl;

    A good reference for the C++ standard library is at www.cppreference.com

    And here at www.cprogramming.com there are some good tutorials and FAQ

    Maybe someone knows of a good I/O tutorial.
