displaying how many words are in an array

[anthony5557]

does anyone know how to make an array search for how many words are in it?

[mrnutty]

Can you give an example of what you mean ?

[anthony5557]

if you ask the user to enter a phrase of no more that 80 characters.

I love programming!

how do you write the part that will search and display the number of words in the phrase. In this case it would be three.

Yes... I do.

See the end of your last thread.

I was thinking about using the .length() but i think that will only count the first word. this is what i have so far.

//Get the user to enter a sentence
	cout<<" Please enter a sentence.\n";
	cin>> Phrase;
	cout<<" The number of words in your phrase is "<<Phrase.length()<<".\n";

Have you debugged your code. You are getting only first word by cin>> Phrase; statement.
Why this is happening? Oh Cin delimits the string by SPACE . Ok, so
You need to get whole line first. Than search all space and count all words i.e. no of space + 1

use getline() and istringstream and your problem should be solved.

use getline() and istringstream and your problem should be solved.

look as far as u have a problem of counting words in your phrase then a solution to your problem is "just count the number spaces in your phrase and add 1 in it". for example in phrase "I Love Programming" there are 2 space characters. 1 after I and 2nd after Love + 1 for last word. so u will get answer 3.

1 more very good solution is use "strtok" and tokenize your phrase on space character. then just count the number of tokens.

i think second solution is better than the first one.

Check out this snippet you have:

//Get the user to enter a sentence
	cout<<" Please enter a sentence.\n";
	cin>> Phrase;
            cout<<" The number of words in your phrase is "
          <<Phrase.length()<<".\n";

If you are ONLY looking for words, not the entire string length, then Phrase.length() won't work because it includes spaces. Pseudocode:
1) User enters string
2) Look for letters only which indicates program is in the middle of a word
3) If space is encountered, ignore it and consider one word in the string to be counted.
4) repeat until end of string

Not quite.

using the stringstream is safer :

string sentence = string("hello this is a sentence");
stringstream phraser;
phraser << sentence;
int wordCount = 0;
string temp;
while(phraser >> temp){
   ++wordCount;
}
cout << "There are " << wordCount << " words in this sentence :' "<<sentence << " ' \n";
