Scramble the word

[scholar]

Hello friends,
there is yet another problem for you...
We have got a string say HOUR
Now we need a program that can choose the specified number of words say n from this word in all possible ways and displays them ...for example in this case
for n=3 the output should be
HOU
OUR
URH
RHO

I've already solved that problem. Perhaps you meant to say "This is my homework".

As much as it sounds like you want us to hand you the solution on a silver platter, I'll offer some advice. Do a google search for generating permutations. C++'s standard library has two functions that allow you to step through the permutations of a sequence, but I imagine your teacher wants you to do it manually.

And what have you done so far? :)

It's rather interesting:
n!/(x!*(n-x)!) different combinations, where n is size of string typed, and x is size of output strings
