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!!
