    floating point (invalid)

    hey guys, i need help with this question.

    i need to write a program to get the output which is :

    i) there will be two class which is info_student and mark_student. class mark_student will be friend to a class info_student.

    ii) class info student will have name and ic with data type character as a variable. it also have function set_data that accept two variable above as a pointer in the parameter list.

    iii) while mark_student will have mark1, mark2 and total with data type float. the function is setmark, calculateMark and display.

    i already programmed and compiled the code, but i have the output show "floating point invalid" when i input the data. what have i done wrong here?

    class info_mark;
    class info_student
    char name,ic;
    int student()
    {return name,ic;}
    class info_mark
    float mark1,mark2;
    int calculate_mark()
    {return mark1 +mark2;}
    void main()
    char a,b;
    float m,n;
    cout<<"mark 1:";
    cout<<"mark 2:";

    You are not even using the classes?

    Exactly what do you enter? Your names can only be one character long!! If your input is incorrect, the variables will just contain garbage.
    I might be wrong.

    Thank you, anon. You sure know how to recognize different types of trees from quite a long way away.
