【C语言】找出1000以内可以被3整除的数

分别用while,do-while,for语句实现

方法一：while

#include<stdio.h>
 int main()
{
     int m;
     m = ;
     while (m<=)
     {
         if (m %  == )
             printf("%5d", m);
         m = m + ;
     }

}

方法二：do-whlie

#include<stdio.h>
 int main()
{
     int m;
     m = ;
    do
     {
         if (m %  == )
             printf("%5d", m);
         m = m + ;
    }
    while (m <= );

}

方法三：for

#include<stdio.h>
 int main()
{
     int m;
     for (m = ; m <= ; m = m + )
         if (m %  == )
             printf("%5d", m);
}
