instead of storing it to char, u should try to convert it to int type, so that when doing swapping of digits, just use the formula that Dr Heng given, 1234 actually to display on screen, is 1*1000 + 2*100 + 3*10 + 4

ok, this should be enough, if i state too clearly, then it's become meaningless, try to figure out.

Hi guys, Dr heng said we should declare tat the work is done ourselves. How do we go bout doing tat? input a \\Work is done by XiaoMing? or do a "cout" stating the work is done by me?

well, the question did mention that n = 1234 is 1 integer.
so if 1234 is 1 integer, how to print it digit by digit ? o_o
still blur here..

The hint is it has something to do with modulus %, try to figure it out..

ok, further hint, using multiplication we can obtain a 4 digits number, so using other type we can obtain the digits seperately.
