Thread: word count help?

Code:

#include <string.h>
#include <ctype.h>

void main()
{
  typedef char* string;
  char s[100];
  int i,alpha=0,space=0;
  printf("Enter a sentence : ");
  gets(s);
  l=strlen(s);
  for (i=0;i<l;i++)
  {
    if( isalpha(s[i]) )
      alpha++;
    else if(isspace(s[i]) )
    	{
      	if(s[i+1]!=' ' && i!=l-1 )
      		space++;
      }
  }
  printf("\nAlphabets = %d",alpha);
  printf("\nWords     = %d",space+1);
  getch();
}

this will count the words properly even if there are several spaces in a row... if the sentence ends in spaces, then also this will work... but if the sentence starts with spaces, it wont work... any suggestions?

use a flag
inWord
set it to 0 at the beginning
on encountering alpha char - switch it to 1
on encountering non-alpha - (or whitespace) switch it back
count words when flag is changed from 0 to 1

Additional notes

main should be
int main(void) - read FAQ

do not use gets - red FAQ


typedef char* string; - do you use it?

Although meldreth's method does cound 123 as a word, as well as any other sequence of characters that aren't whitespaces.

Grr... I think n3cr0_l0rd did not specify the requirements properly. Guessing based on the code posted, I think that both the letter count and the word count should be printed.

I didnt find anything like that in FAQ... can u plz help me?


any yes, meldreths method doesnt print the result line until i press ctrl+c.... (i am using borland 5.02)

finally i did it..

Code:

#include <stdio.h>
#include <string.h>
#include <ctype.h>
#include <conio.h>
int main(void)
{
  char s[100];
  int i,l,letters=0,words=0;
  printf("Enter a sentence : ");
  fgets(s,100,stdin);
  l=strlen(s);
  for (i=0;i<l;i++)
  {
    if (isalnum(s[i])) letters++;
    if (s[i]!=' ' && s[i+1]==' ') words++;   
  }
  if (s[i-2]==' ') words--;
  printf("\nTotal letters(alphabets and numbers) = %d",letters);
  printf("\nWords                                = %d",words+1);
  getch();
  return(0);
}

thx guys.... btw, is there other way to optimize this ?
is there any other way to loop until the end of input string?
