下面的程序错那了？为何不是我要的结果

//IF 0<NUM<99999 ......
ten_thousand=num/10000;
thousand=(int)(num-ten_thousand*10000)/1000;
hundred=(int)(ten_thousand*10000-thousand*1000)/100;//hundred;我抗议,为什么thousand有num-,而我没有
ten=(int)(ten_thousand*10000-thousand*1000-hundred*100)/10;//ten;支持hundred
indiv=(int)(ten_thousand*10000-thousand*1000-hundred*100-ten*10);
//弱弱地问下,这样可以吗,indiv=num%10?
//我暂且相信你下面没有错误(心虚,Sorry),把这些改了先,
//但是我建议;重新设计,使用数组来存放分解的数字,用循环把重复的劳动交给计算机
//这样做的好处;容易扩展到更多的位,但是,你不需要更多的声明和更多的代码行
//你觉得怎么样
/*举个例子
long int TMP;
INT signum;//位数
INT numx[5];
......
for(TMP=num,signum=0;TMP;TMP/=10) numx[signum++]=TMP%10;
//记得,已经反过来了
