C_运用do
源码：
# include <math.h>
# include <stdio.h> /* 数学函数库 */
int main()
{
/* 用s表示多项式的值，用t表示每一项的值 */
double s, t, x; // 此处用双精度声明变量
int n;
printf("please input x: ");
scanf("%lf", &x); // ％lf 代表用双精度输入
/* 赋初值 */
t = x;
n = 1;
s = x;
/* 进行叠加运算 */
do
{
n = n + 2 ;
t = t * (-x*x)/((float)(n)-1)/(float)(n);
s = s + t;
} while (fabs(t)>=1e-8); // 本来是要大于0,但也可大于一个很小的数即可
printf("sin(%f) = %lf\n", x, s);
return 0;
