Declarations

Declarations are statements made within a program’s code that specify the identity and type of variables, functions, or other identifiers before they are used. They serve as an agreement to the compiler or interpreter about how certain elements should be treated, such as indicating that a variable named `age` is an integer. Declarations help prevent errors by confirming the expected data types and structures, enabling the program to allocate the correct amount of memory and ensure proper operation. Essentially, they set the groundwork for the program's logic, organization, and correctness.
