Solution

Please follow the code and comments for description :

CODE :

#include <iostream> // required header files
#include <cstdlib>
#include <fstream>

using namespace std;

string jumbleWord(string word) // function to junble the letters
{
   int count = rand() % 5 ; // get the random count
   if(word.length() > 3) // check for the length
   for(int i = 0; i < count; i++)
   {
       int one = (rand() % (word.length()-1)) + 1; // get two random numbers
       int two = (rand() % (word.length()-1)) + 1;
       char temp = word.at(one); // swap the letters
       word.at(one) = word.at(two);
       word.at(two) = temp;
   }
   return word; // return the letters
}

int main() // driver method
{
   ifstream fin; // local variables
   ofstream fout;
   string fileName, word;
   cout<<\"Enter the name of the input file: \"; // prompt for the user
   cin>>fileName; // get the data
   fin.open(fileName); // opoen the file
   cout<<\"Enter the name of the output file: \"; // message
   cin>>fileName;
   fout.open(fileName); // open the file name
   while(!fin.eof()) // check for the end of file
   {
       fin>>word; // read the word
       fout<<jumbleWord(word)<<\" \"; // call the function
   }
   fin.close(); // close the files
   fout.close();
}

OUTPUT :

main
Enter the name of the input file: input.txt
Enter the name of the output file: out.txt

input.txt :

I couldn\'t believe that I could actually understand what I was reading. Using the incredible power of the human brain, according to research at Cambridge University, it doesn\'t matter in what order the letters in a word are, the only important thing is that the first and last letter be in the right place. The rest can be a total, mess and you can read it without a problem. This is because the human mind does not read every letter by itself, but the word as a whole. Amazing, huh? Yeah and I always thought spelling was important! See if your friends can read this too!

out.txt :

I cou\'dnlt beivele that I could altualcy utderdnans wath I was rgndiae.
