generate strings with all permutation of character [closed]

Answer 1

So, I see you are on VC++10:

#include 
#include 
#include 
#include 

int main() {

    std::array tAlphabet = {
        'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', // and so on...
    };

    // you could store permutations here, but there will be really, really many of them
    std::list tAllPermutations;
    do {
        std::string tCurrentPermutation;

        std::for_each(tAlphabet.begin(), tAlphabet.end(),
            [&tCurrentPermutation] (char tCurrentChar) -> void {
                tCurrentPermutation += tCurrentChar;
        });

        std::cout << tCurrentPermutation << std::endl;
    } while (std::next_permutation(tAlphabet.begin(), tAlphabet.end()));
}
