Count words of a string

[eranga262154]

Hi all,

I want to find the number of words in a string(actually it can be a paragraph either). I found the new line character as follows.

int numberOfWords = 1;
	string st(pBuffer);

	for(int i = 0;i <= st.length(); i++)
	{
		// Newline
		if(pBuffer[i] == '\n')
		{
			numberOfWords ++;
		}

	}

My question is, say I have put more than one new line character at the end or middle of the string. All of them also count as another word of a string. How can I avoid it.

int numberOfWords = 1;
string st(pBuffer);

for(int i = 1;i <= st.length(); i++)
{
	// Newline
	if((pBuffer[i] == '\n') && (pBuffer[i-1] != '\n'))
	{
		numberOfWords ++;
	}
}

Something like that anyway, I haven't tried it.

I've followed quite same way to do this. Here is my code.

bool isLastCharBlank = true;
    int iWordCount = 0;
 
    char * szTemp = szInputString; 
 
    while(*szTemp) 
    {
        // Whitespase, tab, newline and carriage return
        if ((*szTemp == ' ') || (*szTemp == '\n') || (*szTemp == '\r')) 
        {
            isLastCharBlank = true;
        }
 
        else if (isLastCharBlank) 
        {
            iWordCount++;
            isLastCharBlank = false;
        }
        szTemp++;
    }
    cout << iWordCount;

What you think of it.
