Detailed explanation-1: -Programmers declare variables by writing the name of the variable into code, along with any data type indicators and other required syntax.

Detailed explanation-2: -A type declaration statement specifies the type, length, and attributes of objects and functions. You can assign initial values to objects. A declaration type specification (declaration type spec) is used in a nonexecutable statement.

Detailed explanation-3: -It’s best to declare variables when you first use them to ensure that they are always initialized to some valid value and that their intended use is always apparent. The alternative is typically to declare all variables in one location, typically at the top of the block or, even worse, at the top of a function.

Detailed explanation-4: -Coding is the first step to becoming a developer and therefore it is much easier and simpler to start coding. There are many online courses to get you started on learning to code. Programming, however, requires much more specialized knowledge and in many cases, a degree or work experience.
