Question

What is the difference between a static array and a dynamic array in C++?

I have to do an assignment for my class and it says not to use static arrays, only dynamic

Answer 1

static arrary meens with giving on elements in side the array

dynamic arrary meens without giving on elements in side the array

     char a[10]; //static array
       char a[];  //dynamic array
