Why do local variables lose their values between calls to the function in which they are
defined?

Variables which are declared within a function are called Local variables.They are named local because they are used locally only means they cannot be used outside the function in which they are declared.These local variables exist in the memory till the function execution starts and are deleted when the execution of function ends.Hence they lose their value between calls to the function in which they are declared.

i want to say d but i could be wrong however it is organized if that could happen..

hope it could
