输入n位整数，将其每位数字分割打印。
   #include <stdio.h>
int main()
{
   
     long integerLength=0,integerLength2=0;
     long tempNumber=0,Number=0;
     long tempT;
     
         printf("enter a integer:");
         scanf("%d",&Number);
         
         tempNumber=Number;
        
    while(tempNumber>0)
        {
          integerLength++;
          tempNumber=tempNumber/10;
        }
         
          while(integerLength>0)
          {
               integerLength2=integerLength;
               tempT=1;
             while(--integerLength2>0)
             {
                  tempT=tempT*10;
                  
             }      
         
             printf("%d ",Number/tempT);
             Number=Number-Number/tempT*tempT;
             integerLength--;
             tempT=0;
          }
         
         
          getchar();
          getchar();
}

第一句话就是我这个程序实现的功能！功能性的语句帮忙解释下！
