Number of words in a string read from a file

[Tigerlily]

Hello! I need to count the number of words in a string read in from an infile, in a function, but I don't know how to do this. This is what I have so far.

//Tiffany Lynn Goodseit
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
void diffwords(string &line);

int main()
{
string line;

//open input file
ifstream infile("c:\\Dev-Cpp\\phraseinput.txt");
//ifstream infile("con");

while (getline(infile,line))
{
diffwords(line);
cout << line << endl;
}

infile.close();
return 0;


//Function to count the number of words in the entire text
void diffwords(string &line);
{
string line;
int pos, count = 0;

getline (infile, line);
cout << line << endl;


cout << "the is found " << count << "times" << endl;

}
