Question

I’m making a function which receives array of any datatype and reverse it elements.

void f(void *p, int size)
{
  for(int i=0; i<=size/2; i++)
  {
    swap(p+i, p+size-i-1);
  }
}

but problem is how can i implement swap function which swap their content without dereferencing void pointers?

Answer 1

Or you could use the std::reverse function

int main()
{
    int  data[] = { 1, 2, 3, 4, 5, 6, 7};
    std::reverse(data, data + sizeof(data)/sizeof(data[0]));

}
