I’m working on a c programming question and need a sample draft to help me understand better.

Define a function named expappxthat acceptstwo parameters,double zandint n, and returns a double precision real approximationof ezas a summation of n+ 1terms.Assume the existence of a function named factorial(unsigned int k)that you can call (i.e. you do not need to implement the factorialfunctionhere).
