LOCAL VARIABLE Meaning and
Definition
-
A local variable is a term commonly used in the field of computer programming. It refers to a variable that is declared and used within a specific portion of a program, typically within a function or a block of code. Local variables are created within the scope of the section of code where they are defined, and they can only be accessed or manipulated within that particular scope. This means that local variables have a limited lifespan and are only visible to the code that exists within their scope.
The purpose of a local variable is to store temporary or intermediate values that are required for certain operations within the code. These variables are typically used to perform calculations, comparisons, or store temporary results before they are discarded. Local variables are different from variables with broader scope, such as global variables, which can be accessed and modified by any part of the program.
The advantage of using local variables is that they help organize and encapsulate data, reducing the risk of accidental modifications or conflicts with other parts of the program. Local variables also conserve memory resources, as they are generally destroyed once their scope is exited, freeing up memory for other operations.
In summary, a local variable is a variable that is restricted in scope to a specific portion of a program. It is used for temporary storage and manipulation of data within a limited portion of code, offering benefits such as encapsulation, organization, and memory efficiency.

Etymology of LOCAL VARIABLE
The term "local variable" is derived from the combination of the words "local" and "variable".
- "Local" comes from the Old French word "local" which means "pertaining to a place" or "situated in a particular place".
- "Variable" comes from the Latin word "variabilis" which means "changeable" or "liable to vary".
In the context of programming and computer science, a "local variable" is a variable that is defined within a specific scope, such as within a function or a block of code, and can only be accessed and used within that scope. The term "local" indicates that the variable is limited to a specific place or scope, and "variable" indicates that it can hold different values during program execution.
