inta=1;intb=2;intsum=0;for(intn=1;n再问：正确么再答：完整正确的代码如下：#include#include#includevoidmain(){inta=1;intb
#includeintmain(){inti,sum=0;for(i=1;i
main(){inta,sum,i;for(i>0;i
#include"stdio.h"main(){intn,s;n=1;s=0;while(n

#includevoidmain(){inti;doublesum=0;for(i=1;i
sum=sum+1/(5*i+1);这一句,1/(5*i+1)的值是整数的,所以它一直是0这样好像可以sum=sum+(double)1/(5*i+1);
