    resize array of pointers and save

    I have declared a pointer to a pointer(char ** pointer. I can resize an array of pointers now. But how do I pas on the position of where all the pointers are pointing to? I know one way, have a loop and and save everything to a temp pointer then free the memory and allocate more memory. Then have another loop and reasign everything one by one. Is there a faster way or less memory consumming way?

    Thanx in advance!

    Allocate the new array
    Copy your old array to your new array
    Delete the old array

    Or use an expanding data structure from the STL which takes care of this for you, such as list and vector.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
