what's the difference between vectors and arrays in C?
I only knew array, as data structure, and not vector!
When must i use vector and when array?

Thanks

Arrays exist.

There are no "vectors" in C. There are in C++.
Try a C++ news group if you are interested in the
C++ answer.

In C++, a vector is an array with some additional functionality. One of
the main advantages is that vectors support bounds checking: if you use
the at() method, the access will be bounds-checked and throw an
exception if the element does not exist. (You can also avoid bounds
checking by using [], which is overloaded.)

A vector will also grow dynamically as needed when you add elements to
it: an array's size is fixed once and for all when you define it.

In C++, there is a separate type of vector defined in the C++ standard.

In C, you just use arrays.
