Code:

#include<stdio.h>
#include<string.h>
int main()
{
   // freopen("ic.txt","r",stdin);
    char a[200];
    int i,j=0,l,c=0,k=0;
    while(fgets(a,sizeof(a),stdin)!=EOF)
    {
    l=strlen(a);
    for(i=0;i<l-1;i++)
    {
//printf("%d ",i);
//j=i;
if((a[0]==32)||(a[0]==',')||(a[0]=='.'))
{
    k++;


           while((a[k]==32)||(a[k]==',')||(a[k]=='.'))
           {

               //i++;
               k++;


           }
           i=k;
}

        if((a[i+1]==32)||(a[i+1]==',')||(a[i+1]=='.'))
        {
           c++;
           //j++;

           while((a[i+1]==32)||(a[i+1]==',')||(a[i+1]=='.'))
           {

               i++;
               //j++;


           }
        }

    }


printf("\n%d %d %d\n",(c+1),k,i);
c=k=0;
//puts(a);
}
}

problem 1

here i got warning for using EOF. i dont know why i waring.

/media/sda9/c partice/string/word-count.c||In function ‘main’:|
/media/sda9/c partice/string/word-count.c|7|warning: comparison between pointer and integer [enabled by default]|
||=== Build finished: 0 errors, 1 warnings ===|

how i solve this warning?

problem number 2

if i took my input these[space or . or ,]
then i got k value (i-1)
i dont know why.

here is simple input

Code:

...raihan...,,  riya,,,...hmmm

simple output

Code:

3 29 30

here i got k=(i-1)
but how?

pls everybody debug my code and tell me any more error.

Code:

while(fgets(a,sizeof(a),stdin)!=NULL)

try this

am trying to count word . fgets take input if its find space or . or , then word count++ if it find multiple space or . or , then increasse value i till find letter.

That's probably because nobody here understands it. Perhaps you try to rephrase it and tell us what you expect as the correct output (i.e. what should the three numbers 3, 29, 30 represent?)
Your use of meaningless single letter variable names doesn't help either.

pls everybody debug my code and tell me any more error.

Why don't you debug your own code? It's your job!
