Line 5:
In most languages, local variables are [[automatic variable]]s stored on the [[call stack]] directly. This means that when a [[recursion (computer science)|recursive function]] calls itself, local variables in each instance of the function are given distinct [[Memory address|addresses]]. Hence variables of this scope can be declared, written to, and read, without any risk of [[side-effect (computer science)|side-effects]] to functions outside of the block in which they are declared.
Programming languages that employ ''[[call by value]]'' semantics provide a called subroutine with its own local copy of the [[function argument|arguments]] passed to it. In most languages, these local parameters are treated the same as other local variables within the subroutine. In contrast, ''[[call by reference]]'' and ''[[call by name]]'' semantics allow the parameters to act as aliases of the values passed as arguments, allowing the subroutine to modify variables outside its own scope. There are a simple example of local and global variables in C [https://studypointbihar.blogspot.com/2020/02/local-and-global-variables.html?m=1 click here]
