u have to learn how to make a class, do a simple one first. the question already stated all the stuffs needed in that class. I assume u want it in C++,


here's a sample class in PHP (warning, nvr been tested, this is one lazy saturday afternoon's work hehehe)

1. 
   
2. class Marks
   
3. {
   
4.         private $name;
   
5.         private $gpa;
   
6.         private $grade;
   
7.        
   
8.         function set_name($name_from_user_input)  
   
9.         {
   
10.                 $this->name        = $name_from_user_input;
    
11.         }
    
12.        
    
13.         function set_gpa($gpa_from_user_input)
    
14.         {
    
15.                 $this->gpa = $gpa_from_user_input;       
    
16.         }
    
17.        
    
18.         function set_grade()
    
19.         {
    
20.                 if ($this->gpa <= "3.00" && $this->gpa >= "4.00" ) {
    
21.                   
    
22.                         $this->grade = "A";                       
    
23.                        
    
24.                 } elseif ($this->gpa >= "2.00" && $this->gpa <= "2.99") {
    
25.                
    
26.                         $this->grade = "B";
    
27.                   
    
28.                 } elseif ($this->gpa >= "0.00" && $this->gpa <= "1.99") {
    
29.                   
    
30.                         $this->grade = "F";
    
31.                
    
32.                 } else {
    
33.                          
    
34.                           $this->grade = "Wrong";
    
35.                 }
    
36.         }
    
37. }

Is this another way of writing class definition in C++?? Seem so different...Are you writing pseudocode or the real C++ code?

C++ takde $this->function
c++  namaclass->function atau namaclass::function
php are simmilir dengan c tapi senang lagik

zenslack

php - scripting language, tapi underneath php memang C

C++ full OOP programming language

Nope, C++ is not full OOP programming language, contoh yg full OOP programming language adalah JAVA Programming... C++ semi full OOP
