用C语言编程，计算下列级数的值，忽略绝对值 小于“10”的项：f(x)=1-(x/1!)+(x^2/2!）-（x^3/3!)+...+(-1)ⁿ*xⁿ/n!+...

#include <stdio.h>
#include <math.h>

int main()
{
double x, term, sum;
int n, sign;

printf("Enter the value of x: ");
scanf("%lf", &x);

n = 1;
sign = 1;
term = x;
sum = 1.0;

while(fabs(term) >= 10)
{
n++;
sign = -sign;
term *= x / n;
sum += sign * term;
}

printf("The value of the series is: %lf", sum);

return 0;
}
