Question

编程求解100到300以内不能被3,5,7同时整除的数,求这些数之积

运行不了啊

Answer 1

#include<stdio.h>
void main()
{
int start = 100;
int end = 300;
int divide[3] = {3,5,7} ;
double sum = 0;
int i ;

for(i = start;i <= end;i++)
if((i%divide[0])&&(i%divide[1])&&(i%divide[2]))
{
if(sum == 0)
{
sum = i;
}
else
{
sum*=i;
}
}
printf("result is: %e",sum);
}
