Answer / Archna

In C, static variables are used for several reasons: 1) To retain the value of a variable between function calls. 2) To save memory by reducing the number of copies of the same variable when the function is called multiple times. 3) To create a 'static' array that can hold data after the program terminates, if it's explicitly declared with static storage class.

write a C code to reverse a string using a recursive function, without swapping or using an extra memory.
