<prompt> Kuandika C kazi kwa ajili ya nguvu ya haraka.  <response>: Heres an example of a C function for fast power implemented using recursion:double fastPowerdouble base, int exponent if exponent 0 return 1.0; double result fastPowerbase, exponent 2; if exponent 2 0 return result result; else if exponent 0 return base result result; else return result result base;This method calculates the result of raising a number base to a power exponent using recursion and some math tricks to make it more efficient. It uses the fact that xy xy22 to split the exponent in half at each recursive call. It also handles negative exponents since x-y 1xy.
