resizing an array

[trasher]

I suppose I have an array

mystruct* tab[..]

but how can I dynamicly add elements into it ?

I want to have a function like

addElement(myStruct *element)
{
then add *element to my array
}

I just want a hint about how I could do this

thanks

If this is C++ and not 'C', use std::vector instead an array. There is no such thing as a dynamic array, since arrays in C++ are always fixed. So you either must use pointers with new and delete, or preferably, just create a vector of your items.

Using vector:

#include <vector>
typedef std::vector<myStruct> MyStructArray;

MyStructArray MArray;;

void addElement(myStruct& m)
{
MArray.push_back( m );
}

You can now use MArray just like an array, including using operator [] to access and set elements.

You can't add elements to a statically-bound array. You'd either
have to create your own array with malloc() or new[]. Hopefully,
you're using C++; if so, you can use std::vector instead of using
a statically-bound array:

std::vector<mystruct*> v;
v.push_back(pStruct);

times :)

thanks!

I will look for std::vector...

When I was doing C, it was so painfull to use malloc and realloc
