c - 如何计算输入文件中数字的倍数？

Question

我试图从用户输入文件中分别计算 2、3 和 6 的倍数数量。但由于某种原因，我的计数器不工作。任何博西可以帮助我吗？我的代码:

#include <stdio.h>
int main (void)
{
  int num[12];
  int i;
  int counttwo;
  int countthree;
  int countsix;
  int total=0;
  printf("enter 12 integer numbers:\n");
  for(i=0;i<12;i++){

 scanf("%d", &num[i]);
  }
  for(i=0;i<12;i++){
    counttwo=0;
      if(num[i]%2==0){
       counttwo++;
      }
      countthree=0;
       if(num[i]%3==0)
  {
      countthree++;
   }
       countsix=0;
      if(num[i]%6==0)
        {
          countsix++;
}
      printf("There are %d multiples of 2:\n", counttwo);
      printf("There are %d multiples of 3:\n", countthree);
      printf("There are %d multiples of 6:\n", countsix);
}
  return 0;

}

Answer 1

您在每个迭代步骤中重置计数器变量。把

counttwo=0;
countthree=0;
countsix=0;

for()之前的代码。
