How do count the amount of words in a string?

[SlenderMan]

How can I make the program read what the user typed in and print out the amount of words in the phrase the user entered. Also, after you hit yes to play again, it skips over taking in the first phrase and goes straight to the second. Why?

#include <iostream>
#include <string>
#include <conio.h>
#include <iomanip>
using namespace std;

int main()
{
	char response;
	int value = 0;
	char msg1[80] = "";
	char msg2[80] = "";

	do
	{
		cout << "Enter a phrase: ";			//get phrase one
		cin.getline(msg1, 80);

		cout << "\nEnter another phrase: ";	//get phrase two
		cin.getline(msg2, 80);

		strtok(msg1, msg2);

		cout << "\nPhrase \"" << msg1 << "\" has " << strlen(msg1) << " characters.";		//display amount of characters
		cout << "\n\nPhrase \"" << msg2 << "\" has " << strlen(msg2) << " characters.";

		value = strcmp(msg1, msg2);

		if(value == 0)
			cout << "\n\nIn C++, phrase \"" << msg1 << "\" is equal to the phrase \"" << msg2 << "\"";		//determine which phrase is greater
		else if(value > 0)
			cout << "\n\nIn C++, phrase \"" << msg1 << "\" is greater than the phrase \"" << msg2 << "\"";
		else if (value < 0)
			cout << "\n\nIn C++, phrase \"" << msg2 << "\" is greater than the phrase \"" << msg1 << "\"";
	
		cout << "\n\nPlay again(y/n)? ";
		cin >> response;
		response = toupper(response);

		while(response != 'Y' || response == 'N')
		{
			if(response == 'N')
			{
				cout << "\nprogram ends.";
				break;
			}
			cout << "\nEnter a valid option: ";
			cin >> response;
			response = toupper(response);
		}	
	}
	while(response == 'Y');

	_getch();
	return 0;
}

In the most basic version you shuld just loop through each character in a string, then count how many times a whitespace character was hit.

[SkyDriver2500]

Try creating a loop something like:

int b
for (a=0;a>80;a++)
{
if [msgl[a]==x] //change x with the ASCII table number of white space
{
b++ //b should store the number of spaces
}
}

I'm not sure if this works but it is what i would do.
Hope it helps

loop from first index to theString.lenght()

if( theString[index] == ' ' )
words++;

make sure you initialize int words to 1
