Write a program to print all permutations of a given string

Image
A permutation, also called an “arrangement number” or “order,” is a rearrangement of the elements of an ordered list S into a one-to-one correspondence with S itself. A string of length n has n! permutation. Below are the permutations of string ABC. ABC ACB BAC BCA CBA CAB. Source Code:  Download the code  : Permutation of string #include <iostream> #include <string.h> using namespace std; int count=0; void swap(char *x, char *y) {     char temp;     temp = *x;     *x = *y;     *y = temp; } void permute(char *a, int l, int r) {    int i;    if (l == r)    {     count++;     cout<<count<<": "<<a<<"\n";    }    else    {        for (i = l; i <= r; i++)        {           swap((a+l), (a+i));           permute(a, l+1, r);           swap((a+l), (a+i));        }    } } int main() {     char str[100];     int n;     cin>>str;     cout<<"\nPermutations of the given string :\n";     n = strlen(s
