Number of word in one text

[plc]

Hi,

I'm trying to do a program to count the number of words in a text, and show the average of words per line. How can I count the number of spaces and "enters" in a text?

Thanks

Forget about counting the spaces; do you know how to find spaces and enters (i.e. newline characters, '\n')? If you know how to search for these, then counting is simple.

Ganon11,

I don't know how to use this. How can I use this?

Do you know how to get input from the file, one whole line at a time? If so, then do you know how to use the find() method of the string class? If so, then you have all the information you need.

Are we even talking C++ here? Or is it C?

But yes, the first step would be getting input properly. With C++, this is easily accomplished with the getline function for strings, and with C, fgets.

I know how to use the getline, but how can I use find()?

You'll want to do some reading.

I did that:

#include <iostream>
#include<fstream>
#include <string>
using namespace std;
 
void main (void)
{
    ifstream fichier;
 
    char ar[10000];
    int i, word=1;
 
 
    fichier.open("F:\\td3_ex3.txt");
 
    while (!fichier.eof())
    {
        fichier.getline(ar,10000);
    }
 
    for (i = 0; i < strlen(ar);i++)
        {
 
 
         if (ar[i] = '  ')
              {   word=word+1; 
         }
    }
 
     cout << "no. of words = " << word;
}

the text that I supose to read are quite long, and it's only showing the first 49 words. What;s the lenght of a char? And what should I do to find the enters?

A two-parameter getline call gets one line, ended by '\n', the newline character that amounts to an enter, which is dropped from the string. getline also clears the string before it appends, so all you'll get is the last line if you use that. Also, if the third parameter, which defaults to '\n', is found by the input reader, it stops getting input even if the character number has not been reached.

[Ganon11]

Why are you using character arrays in a C++ program!? Using a std::string will make your life much easier here.

[scarecrow13]

You could use the get() function so as to read each character and whenever a white space character excluding '\n' is read it updates the counter.

Actually I need both, because I need the to print the average of words per line, so I need the numbers of words and the number of lines.
