In Unreal Engine, instead of writing `signed long long` for an 64-bit integer, you can now write `int64` instead. These alias are called **typedefs**, which you can read more about [typedef keyword in C++ docs](https://en.cppreference.com/w/cpp/language/typedef).
You can read more about C++ typedefs in [this section](#typedefs).
Here is s full list of Unreal Engine's typedefs:
The "an 64-bit integer" should be "a 64-bit integer".
The "These alias are called" needs the "alias" to be plural as in "These aliases are called".
Replace the "s" in "Here is s full list" with "a" as in "Here is a full list".
