How to get an 'instant copy' of an array returned by a function used two times ....

[tonnot]

The title space is not enough to explain my problem.

I have a my_function at class A:

void my_function(char array1[],char array2[]);

void my_function(char array1[],char array2[]);

To copy to clipboard, switch view to plain text mode 

I call it so:
my_function(classb->give_me_array(22), classb->give_me_array(33));

'Give_me_array' located at another class B, receive an index and fill the internal array with 5 values.

char * give_me_array(int index) {
fill internal_array....
return internal_char_array;}

char * give_me_array(int index) {
fill internal_array....
return internal_char_array;}

To copy to clipboard, switch view to plain text mode 

internal_char_array is a char array[5] declared as private for this class

Ok, my problem is that my_function receives the value for 33 also for 22. ( I think that this is a pointer problem) . How to solve this ?
I'd not want to use two aditional arrays and function calls to solve the problem.
Any idea ?

I'd need a trick to make an instant copy ....

Thanks

void give_me_array(int index, char* outputArray) {
fill internal_array....
strcpy(outputArray, internal_char_array);
}

void give_me_array(int index, char* outputArray) {
fill internal_array....
strcpy(outputArray, internal_char_array);
}

To copy to clipboard, switch view to plain text mode 

When you call give_me_array, make sure "outputArray" has enough space (i.e. greater than 5 bytes if your internal_char_array is always char array[5)

Ok, but to do this I need an external outputArray ....
As I know I can call this function two times in the same line, a trick could be having two internal arrays to return the internal_array1 or internalarray2 ... ?
What do you think ?

Well, what can I tell you, your code design is wrong.

Why you want to return a pointer that points to your private class member ? Any user of your class may change your private member without your knowledge.
In the best case I would return a const pointer, but this is also a bad scenario in some situations.

Why don't you just use QList or QVector ? It will save you a lot of coding.

Thanks to everybody and for the ideas
