c ++: transferring a value from a constant to a non-constant structure (an error is generated)

Question

Tell me how to fix the following error:

There is a data structure:

struct CMyData { int m_data; };

There is a constant pointer to this structure.

 const CMyData* ptr = _get();

I want to write to another structure a pointer to the data from the first

 myData2.m_ptr = &ptr->m_data;

And I get an error

error C2440: '=': cannot convert from 'const CMyData :: int *' to 'CMyData :: int *'

Corrected by abolishing the constant, i.e. So:

 CMyData* ptr = _get();

But I want to adhere to the minimum functionality - I'm not going to change the ptr itself, that's why I declared it a constant.

Well, in the second structure, declare the m_ptr field not as int* , but as const int * ...
const CMyData* ptr is not a "constant pointer", but a "pointer to a constant structure"
will there be a constant member in the structure and at the same time I can only change it from the constructor during initialization and in the situation I described above?
@ Fat-Zer this is the reason for my misunderstanding :) Now I understand, really const belonged to another part.
