i need the answer quickly Q1) Write a C++ program to compute the value of S using function called Compute_S(x, n), wherethe value of S(x, n)= - (X)/1! + (X*)/2! - (X)/3! + (X*)/4!Compute S(x, n) uses another function called Compute Term(x, i) function to compute the terms+ (X2)/i! during the iteration i. The function Compute_Term(x, i) uses three static variablessign=-1, pwrX-1, Fact=D1. The variable sign is changed each call from -1 to 1 or from 1 to -1, thevariable pwrX multiplied at each call by x (i.e. pow(x, 2)) to compute x2 from x2"G-1)(ex:x=x+*x? , pwrX= pwrX* x), and the variable Fact calculate the factorial of i based on thefactorial of (i-1) starting from 1 ( ex: fact(i)=i*fact(i-1)).+ ( X2n)/n!. The function.....

Here I have created the function pwr(). In this function if the value of y is 0 then return 1,…

program to com using n), W he value of S(x, n)= - (X)/1! + (X*)/2! – (X)/3! + (X®)/4! Compute_S(x, n) uses another function called Compute_Term(x, i) function to compute the t E (X(2)/i! during the iteration i. The function Compute_Term(x, i) uses three static varia sign=-1, pwrX=1, Fact3D1. The variable sign is changed each call from -1 to 1 or from 1 to -1 variable pwrX multiplied at each call by x? (i.e. pow(x, 2)) to compute x2 from x ex:x=x+*x2 , pwrX= pwrX* x), and the variable Fact calculate the factorial of i based or ... ± ( X2n)/n!.
