这是一道C程的题目：输入精度e,用下列公式求cos x的近似值,精确到最后一位的绝对值小于e.要求定义和调用函数求函数近似值、cos(x) = x^0/0!－x^2/2!＋x^4/4!－x^6/6!＋……这是我的答案.为什么显示溢出?#include#includemain (){double e,x;double cos(double x);scanf(%lf%lf,&e,&x);print

double cosx(double x);
scanf(%lf%lf,&e,&x);
printf(%f\n,cosx(x));
return 0;

double function(int i);

while(fabs(item)>e){item=flag*pow(x,i)/function(i);
