c语言编程，求各位高手帮帮忙！！！！

#include

int main()
{
int x,n = 2;
long m = 1;
double sum , res;
int f = 1;

scanf("%d",&x);

sum = x;

printf("s(%d) = ",x);

while(1)
{
m = m*n*(n+1); /*分母*/

n = n+2;

x = x+2; /*分子*/

res = (double)x/m;

if(res<1e-6)break;

sum = sum+res*f;

f = -f; /*符号*/
}

printf("%lf",sum);

return 0;
}
