Description: A function variable is a variable defined within the scope of a function in programming. This means that its scope is limited to that specific function, and it cannot be accessed from outside it. Function variables are fundamental for data encapsulation and modularity in programming, as they allow functions to operate with temporary data without interfering with other parts of the code. Being local, these variables help avoid naming conflicts and maintain the function’s state without affecting the global state of the program. In general programming languages, function variables are created simply by assigning a value to a name within the function, and their lifecycle is limited to the execution of that function. Once the function finishes executing, function variables are destroyed, and their memory is freed, contributing to efficient resource management. This feature is especially useful in programming paradigms such as procedural and object-oriented programming, where the goal is to keep the code clean and organized.
