C++ requires a type specifier for all declarations
i really don´t know what this means. i overview the video a few times.
When you first declare a variable in statically typed language such as C++ you must declare what that variable is going to hold.
int number = 42;
number = 42
Edit to add: There's a pretty good StackOverflow post on the difference between static and dynamic and strong vs weak variables in languages.
