Hi! I don’t understand what the #include <vector> does.

#include <vector> adds the standard vector library to your program. You need to do that before you can use any vectors in your program. I hope this helps!

Can anyone explain the syntax for defining vectors. < >. What do the carrots do? Will we see this carrot usage again with other coding elements? So far I’ve seen std::cout<< and std::cin>> and now std::vector.

My only guess is that the arrow directions have to do with the information flow, but I don’t know.

i know it has been a year but if you do see this it is a bracket for information so std::vector<> declares what kind of varible so int or double
