How to get a sentence?

[oLC9216C]

I want to get a sentence. also check how many words in the sentence.

I tried to use string like this

string line;
cin >> line;

For example I enter "how are you"
But the value of line is only "how"

How can I get the whole sentence?
Also how can I check the third word in the sting?

If there is one sentence per line, you can use:

string line;
getline(cin, line);

If you are reading from a file and there may be multiple sentences per line, you can delimit with a period:

string line;
getline(cin, line, '.');

to get a whole line instead of cin >> line; which only gets the first word use this
getline(cin, line); this gets the whole line =p
and as far as a word count you can do something like this:

unsigned int num = 1;
for(unsigned int i = 0; i<str.size(); i++) if(str[i] == ' ') num++;
    cout << "Word count is: " << num << endl;

Is it possible to read what is the first three element in the string?

[giblit]

You mean only read in the first three words?
you would have to modify the other code I gave you so that after num reaches 3 it stops reading it but im pretty tired so gl.
