Key Concepts

Variable Declaration

This is the process of specifying a variable's type and name in a programming language so that it can be used to store values. A proper declaration defines the memory allocation and the scope of the variable within a program.

Variable Scope

Variable scope determines the parts of a program where a declared variable can be accessed. Different scopes, such as global, local, block, or method scopes, restrict a variable’s visibility and lifetime, influencing how and where variables can be reused.

Block Scope

Block scope refers to variables that are confined within a block of code, typically defined by curly braces. In many programming languages, variables declared in one block are not visible outside of it, which allows for the reuse of the same variable names in different blocks without conflict.
