Can you show us how to return a single word that we have counted?

[florent]

so what do you get doing *pStr? the actual character? And what do you increment if you do pStr++? the address of the pointer? Further on I dont get the line where you check ++len == 1, would be nice if you could explain a little more in detail. Thank you.

[cadetxero]

Can this be applied to pattern matching as well ?

#include <iostream>
#include <string>

using namespace std;

int wordCount(const string& str);


int main()
{
string str = "How are you?";
cout << wordCount(str) << endl;
return 0;
}

int wordCount(const string& str)
{
int i(0);
bool b(false);

str.empty()? b : b =true;

if (b)
{
i = 1;
for(const char& c : str)
{
if(isblank(c))
{
i++;
}
}
}
return i;
}
