Print all the permutations of a string in C

Question

I am learning backtracking and recursion and I am stuck at an algorithm for printing all the permutations of a string. I solved it using the bell algorithm for permutation b

Answer 1

I create more specific but not efficient Program for permutation for general string.
It's work nice way.
//ubuntu 13.10 and g++ compiler but it's works on any platform and OS
//All Permutation of general string.

#include
#include
#include
#include
using namespace std;
int len;
string str;

void permutation(int cnum)
{
    int mid;
    int flag=1;
    int giga=0;
    int dead=0;
    int array[50];
    for(int i=0;i
