I’ve got a really messed up, non working solution for ex. 5.1 of Accelerated C++ [closed]

  accelerated-c++, c++

I am currently trying to learn the basic C++ with Accelerated C++.
I tried to create my own solution for the ex. 5.1 in the book but the program got kind a complicated and I was not able to find a solution to errors that I got when I compiled it.
If someone can help me improve this code and criticize me I’d be really grateful.

Design and implement a program to produce a permuted index. A permuted index is one in
which each phrase is indexed by every word in the phrase. So, given the following input,

The quick brown fox
jumped over the fence

the output should be:

      The quick   brown fox
jumped over the   fence
The quick brown   fox
                  jumped over the fence
         jumped   over the fence
            The   quick brown fox
    jumped over   the fence
                  The quick brown fox

And now, my solution:

//Here's my code for the exercise 5.1 of ACCELERATED C++
//I can easily tell that I messed up big time in this code and got 
//everything complicated (it doesn't run and I can't resolve the errors)
