用C语言编写程序,求S=1+（1/2!）+（2/3!）+·····+（n/（n+1!））,直到最后一项的绝对值小于10^-5

#include stdio.h
double calcS(double t)
{
int i = 1;
double retValue = 0;
double sglValue = 1;
double dFenzi = 0;
double dFenmu = 1;
do
{
dFenzi += 1;
dFenmu *= (i+1);
sglValue = dFenzi/dFenmu;
retValue += sglValue;
}while(sglValue > t);
return retValue;
}
void main()
{
printf(calcS(0.00001) = %lf,calcS(0.00001));
