Homework Answers
Static Variable:Static Variable consists of a property of preserving the value even after they went out of their scope.It willn't be initialized again in the new scope.
Static variables are initialized with zero(0) by default.
Why use Static local variable?
Static local variables are GLOBAL VARIABLES.
Static local variable intialize only once inspite of how many times the function in which the variable is present called.
These variables doesn't required run-time overhead for allocation and de-allocation.
Direct access of these variables are more efficient.
This variable will create at statring of the program and destroys at the end of the program like gloabl variables.
These variables are used in cases like counting the no. of executions of a function.
Disadvantages of Static local Variable:
Static local Variables doesn't support Recursion.
Their storage can't be supported with other inactive sub-programs.
Static local variables aren't allowed in java.
