86. Using LVTI in compound declarations

A compound declaration allows us to declare a group of variables of the same type without repeating the type. The type is specified a single time and the variables are demarcated by a comma:

// using explicit typeString pending = "pending", processed = "processed",        deleted = "deleted";

Replacing String with var will result in code that doesn't compile:

// Does not compilevar pending = "pending", processed = "processed", deleted = "deleted";

The solution to this problem is to transform the compound declaration into one declaration per single line:

// using var, the inferred type is Stringvar pending = "pending";var processed = "processed";var deleted = "deleted";

So, as a rule of thumb, LVTI cannot ...
