A c++ program to show all meaningful permutations and combination of word???

Answer 1

Ther is standart library for that. it have next_permutation method

But about meaningful... Just check it in dictionary

Answer 2

Now this is interesting. Cross swapping the characters in a string to form a new string is easy, but how are we supposed to evaluate if the word is meaningful or not? I can surely hook the program up with a dictionary, but the array size needed to store all the information would be too big and inefficient. I'd like to hear out on how others would counter this problem.
