Hi all,
   I want to copy intermediate elements from a vector to another.
   The problem is I am getting same value in m_Data[6] ...[11]for all
elements.(&srcPtr[0] value- for exp 205).
   Am I missing anything?

                   std::vector<uint_8*> (m_Data);
                    uint8_t *srcPtr = new uint8_t[6];
                    memset(static_cast<uint8_t*>(srcPtr), 0,(sizeof
(uint8_t)* 6));
                    if(srcPtr)
                    {
                                           srcPtr= // A API returning
const_uint*
                    }
                    m_Data[6] = &srcPtr0];
                    m_Data[7] = &srcPtrr[1];
                    m_Data[8] = &srcPtr[2];
                    m_Data[9] = &srcPtr[3];
                    m_Data[10]= &srcPtr[4];
                    m_Data[11]= &srcPtr[5];

Hi.

You have completely misunderstood pointers.

And also the "m_" prefix convention, and a lot of other things.

What you should do is just

std::vector<uint8_t> data;

But you need a good textbook, and you need to start at the start of that.

Sort of like Hillary Clinton's effort to "restart" relations with Russia instead
of digging deeper into existing hole, but don't use a button that doesn't work
and is labeled with insulting language; use a good textbook.

Cheers & hth.,

No ads, and there is some C++ stuff! :-) Just going there is good. Linking
