Question

Write a C++ program that inputs (cin) a word from the keyboard and generates several different scrambles of the word without using vectors. The input word can be from 4 to 10 letters in length. The number of scrambles produced depends on the number of letters in the word. e.g. the 4 letter word “lose” would have 4 different scrambles produced and the seven letter word “edition” would have seven different scrambles.

Here is a candidate example:     

Input: FLOOR

                Scrambles: ROOLF, OOLFR, OLFRO, LOORF, OORFL

Your program must use the same block of code for each input word. There is also the rand() random number generator available.

Test you program with these words:

salt
asteroid
manipulate

Answer 1

Here you go:

#include <iostream>

#include <algorithm>

#include <ctime>

#include <cstdlib>

#include <string>

using namespace std;

int main()

{

    srand(time(0));

    int i,len=0;

    string input;

    cout<<"Input: ";

    cin>>input;

    len=input.length();

    std::string output = input;

    if(output.size() >=4 && output.size() <=10){

    for(i=0; i<len; i++)

    {

            std::random_shuffle(output.begin() , output.end());

            std::cout << output << ' ';

        }

    }

    else

    {

        return 0;

    }

}
