int main()
{
const int i = 42;

*(int*)&i = 43;       // What is happening here

printf ("i %d,%d,%d",i,*(&i),*(int*)&i); // Why the result is 42 42 and 43

return 0;
}

please see the comments. why the result is 42 42 43

The result can be as well 3 14 43549059.
This is not valid C++ code. You are breaking the type system here.

the problem is that you're removing const. If you're writing this 'i' or '*(&i)' the compiler knows that it's the constant 42 and replace the expressing accordingly. When you cast away the const it uses the variable which is set to 43 previously.
