| My coding idea about inheritance for phones  so i would like to share here about the errors and others. any help is appreciated... now my uml diagram i want to transfer to handwritten coding.so.. Quote:
here's my work...any comments ideas or something..i think it's ok.. Code: class Handphone
{
private:
string phoneNumber;
string message;
double credit;
string inbox[N*];
int object_counter;
public:
Handphone ( string no, double cr,double rate)
void smsEdit();
void smsRead();
}
Class Smartphone : public Handphone
{
private:
image mms_message;
image mms_inbox[N];
public:
void operator>>(Smartphone &s);
void mmsRead();
void mmsEdit();
}
can anyone explain what is string[N*] inbox; and image[N] mms_inbox; what is the data type like?? why does it have a bracket?like[*] and [] the initial i suppose it's a pointer thing. Last edited by MyRedz; 10-22-2009 at 11:34 AM. Reason: correction of errors | |

| Well I assume it's a declaration of an array, but it's all wrong. In fact, there's a pretty blatant mix of Java/C#/C++ in this code. The way that those classes and arrays are declared is more of the Java/C# way of doing things. This code won't compile in any of the 3 languages. Last edited by DavidP; 10-22-2009 at 08:09 AM. |

| Why do you think string[N*] inbox means anything at all? |

| i think in your code which is not pasted you will be having N as #define N with some value and thats why image[N] mms_inbox will become an array of image |

| wow...no wonder even myself can't do the uml diagram to code properly.. it is a mix of 3 languages... so your ideas... how to make it compilable in the end?this is sure tricky but i just have to try it! is my brief coding part from uml ok? string[N*] inbox means it is a declaration of inbox size if i am not wrong in a array of N pointer is it? well for N is just the box size in here Quote:
for inbox:string[N*] mms_inbox:image[N] where can i learn more about mirror image?it isn't found in c++.. | |

| So that means you need to pick a language. I don't think any of us particularly care which language you pick, so you should pick the one you're most comfortable with. The * doesn't seem to be meaningful from the language sense; the description makes it sound as though it is a parameter, as opposed to a member variable or something, so perhaps whoever wrote your UML is using * in that way. Why do you want to know something about mirror image? |

| ok..* is clear a bit to me..thanks... mirror image is something new to me. can you show some examples.. well the language i choose is c++.. so my initial coding from uml is it correct? |

| ok.i corrected it.. string inbox[N*]; int object_counter; image mms_inbox[N]; so this are the faults is it? is this ok?i want to proceed to making the descriptions for each class |

| So string inbox[N*] still doesn't make any sense. If you want an array of N strings, then just do that. (I suppose it's possible you want an array of pointers-to-strings, but it seems unlikely to me somehow.) |

| well i know it's unlikely but then in the uml it says inbox:string[N*] and it's usage is N*: inbox size (i.e., the number of sms that can be stored, e.g. 10).. well it's usage is for the main purpose of the project that is. inheritance from handphone to smartphone which means from text message to picture message or mms ones. can i proceed to the descriptions?
