Pointers to Vectors

Pointers to Vectors

How do you create an array of pointers to vectors?The different vectors will, eventually, have different lengths.

You declare an array of pointers to vector like this:

  std::vector * vecptrarr[10];

Of course, you’ll need to allocate the vector object at a later stage and assign addresses to the pointers in the array. I also recommend that you initialize the array to null pointers to avoid the dangers of dangling pointers:

  /* initialize all array members to 0 */  std::vector * vecptrarr[10] ={0};
