Append element to array
Hello. I'm new at C++ coming from a good experience with Python.
I have an array
I would like to add an element to said array. In Python I would do
How do I do something like this in C++? How can I add an entry to the end of an array?
Thanks!

The kind of array you're thinking of is called "std::vector" in C++:

(caveat: old compilers couldn't use this handy initialization syntax, you had to insert "a", "b", and "c" with indivudual push_backs or use an intermediate array: string a[] = {"a", "b", "c"}; vector<string> x(a, a+3); )

Tnx ! for the above. !
I've always used the intermittent array, I'll try this from now-on.

Initializer lists are a feature of C++11. You may need to set up your compiler to use them (mine is turned off by default)
C arrays (those defined by square brackets) cannot be resized
