Question

What precisely do you mean when you say "declaration statements"?

Expert Solution
Step 1

Introduction:

A variable, function, class, or another identifier can be declared using a declaration statement. They give a mechanism for the compiler to be informed about the name and type of the identifier. A type, an identifier, and a semicolon are commonly included in declaration statements. For instance, the statement int x; declares a variable of type integer.
