How to set a map?!!!

[coll97]

I have a vector like: vector<string> Phrase;
and a map like: map<int,Frase> AllPhrases;

And the text like:
What if to taste and see, to notice things. To stand each is up against emptiness
for a moment or an eternity. Images collected in consciousness like a tree alone on the horizon.

And the result of the map has to be:

1 What if to taste and see, to notice things.
2 To stand each is up against emptiness for a moment or an eternity.
3 Images collected in consciousness like a tree alone on the horizon.

Please how can I do that?

Thanks a lot

Is your test already separated out into the three different phrases, in that vector<string> Phrase?

If so, then:

1) Iterate over the elements in Phrase.
2) For each element, add an entry to AllPhrases, that has the element index as a key, and the element itself as the value.
3) PROFIT!!!!

int n = 1;
string s;
while(cin >>s){
int k = s.size()-1;
if(s[k] != '.'){
Phrase.push_back(s);
}
else{
Phrase.push_back(s);
AllPhrases[n] = Phrase();
Phrase.clear();
++n;
}
}

I have this but it doesn't work, it doesn't compile :'(

Is there any reason why you chose to withhold all that helpful information your compiler is giving you about why it doesn't compile, and which lines the errors are on?

Why are you clearing Phrase when the last element of s is a

The line:

AllPhrases[n] = Phrase();
has what looks like a function call to a function called Phrase. I suspect that's not what you really wanted to do, right?
