Thread: problem on counting the total no of words in each paragraph

I can succesfully count the first paragraph from the input text file. However, I feel helpless in the part of counting the words in other paragraphs.

Code:

          ch=fgetc(infp);       
          while(ch!='\n')
          {
            if(ch==' ')
            count_pw++;
            ch=fgetc(infp);
          }
          printf("Number of words in paragraph 1: %d\n",count_pw+1);

          ch=fgetc(infp);    //this part is to count the total no of paragraphs
          while(ch!=EOF)
          {
           if(ch=='\n')
           count_p++;
           ch=fgetc(infp);
          }
          
          ch=fgetc(infp);   //this part really makes me feel puzzled
          while(ch!=EOF)
          {
            for(i=1;i<count_p+1;i++)
            for(j=0;j!='\n';j++)
             if(ch==' ')
             count4++;
             ch=fgetc(infp);
          }
            printf("Number of words in paragraph %d: %d\n",i+2,count_pw+1);

Moreover, I want to ask if there is method to detect the first character to count the words(I count words by counting spaces), so that the total number will not include those spaces at the start of each paragraph.

You're program counts the number of blanks, not the number of words. There is a difference. If you have 3 consecutive blanks, you will get a count of 3, and there might not be ANY words.

As Desolation said, a simple method is to use strtok(), but that would require you to change your program to work with strings instead of characters.

If you want to work with characters, then add a state flag: (not syntax checked)

Code:

int in_word = 0 ;  /* state flag - set to false initially  */ 
ch=fgetc(infp);       
while(ch!='\n') {
    if (ch==' ') { in_word = 0 } ;   // turn state flag off 
    else if (!in_word) {   // if we weren't in a word... 
          count_pw++;    // bump count of words - we just found one 
          in_word = 1 ;   // turn state flag on 
     }
     ch=fgetc(infp);       // Get another char
}

As for your other question - ask yourself this. In the following code...

Code:

       ch=fgetc(infp);    //this part is to count the total no of paragraphs
          while(ch!=EOF)
          {
           if(ch=='\n')
           count_p++;
           ch=fgetc(infp);
          }
          
          ch=fgetc(infp);   //this part really makes me feel puzzled
          while(ch!=EOF)

When the first EOF is hit, what will it take to reset the EOF flag?

Thanks for all of your help. I can now solve my second problem, that is counting no of words but not counting spaces.

Yet, for the solution of my first problem, I still don't really get it. Is that I should make a function of finding the no of paragraphs? Or what does readParagraph mean and use for in counting the words in each paragraph?

It really stems from your definition of a text file.

A file is composed of one or more paragraphs.
A paragraph is one or more sentences.
A sentence is one or more words.
A word is one or more characters.

I mean that paragraphs are counted when pressing enter. And after finding total no of paragraphs, I have tried to use strtok after reading its use[URL="http://http://www.cplusplus.com/reference/clibrary/cstring/strtok.html"]

But now, there is some problem here. Would someone tell me how to solve it? I would be thankful for your help.

Code:

          ch=fgetc(infp);
          while(ch!=EOF)
          {
           if(ch=='\n')
           count_p++;
           ch=fgetc(infp);
          }
          printf("Total number of paragraph(s):%d\n",count_p+1);

          do{
             t1=strtok(all_word,'\n');
             count_pw[20]=0;
             while(fgets(all_word,300,infp)!=NULL)
             {
              for(i=0;i<count_p+1;i++)
              {count_pw[i]++;
               printf("Total number of words in paragraph %d: %d\n",count_p+1,count_pw[count_p+1]);
               t1=strtok(NULL,'\n');             
             }
            }while(fgets(all_word,300,infp)!=EOF);

first as salem said define a paragraph

if you have done that:
>if you find two or more consecutive places replace them with one... you can use isspace() you should also consider tab....
>after that you need to print the number of words at the point you encounter a new line character....or endoffile
>also take care to ignore spaces at the beginnig of a paragraph...
>by replacing spaces here i mean when you find 2 or more consecutive spaces read them as one...
by this i think you can count number of words

printf("Number of words in paragraph %d: %d\n",i+2,count_pw+1);

doesnt make sense...
i think that should be in the loop
