Display the result of 1/1! - 1/2! +1/3! -..... By c programming

Question

someone pls post a solution

Answer 1

idk about c but you could translate it. and if you have 1/8, just as integers.... u gunna get 0 for everything....

double fac(int f){
if(f == 1)
return 1;
else
return f*fac (f-1);
}

double a = 1.0, sum = 0.0;

for(int x = 1; x < n; x++){
if (x%2 ==0)
sum -= (a/fac(x));
else
sum += (a/fac(x));
}

hope this helps!!
