the english words.output
a list of the words by alphabet and the count of the each word into a
file such like output.txt
e.g.the input.txt is:

Hello world.
Hello every one.
Let us go.
and the output.txt is:

world,1
I remember some book has the answer ,but i can't remember the name of

[code break]

No u have try by manually(i.e by your skill)

[rrs.matrix]

u can start off with this code..
mind u it has a some bugs, but it can get u started..
the program will repeat the search for words that have been searched;
also it does not consider the '.' after at the end of a line.
u will have to finish it up.

#include<stdio.h>
FILE *rptr;

int main()
{
int wcount=0;
char str1[50],str2[50];
long cpos;

rptr=fopen("input.txt","r");
fscanf(rptr,"%s",str1);
while(!feof(rptr))
{
cpos=ftell(rptr);
wcount=1;
str2[0]='\0';
while(!feof(rptr))
{
fscanf(rptr,"%s",str2);
if(strcmp(str1,str2)==0) wcount++;
}
printf("\n%s:%d",str1,wcount);
fseek(rptr,cpos,SEEK_SET);
fscanf(rptr,"%s",str1);
}
return 0;
}

wdfreq, which is one of the demos for hashlib, available at:

<http://cbfalconer.home.att.net/download/hashlib.zip>

produces:

[1] c:\c\hashlib>wdfreq
Usage: wdfreq < inputfile > outputfile
collects all words in inputfile and outputs a
sorted (by frequency) list of words and the
frequency of their occurences, ignores case.

Signal EOF to terminate (^D or ^Z usually)
hello world
hello every one
let us go
^Z
8 words, 7 entries, 10 probes, 2 misses
2 hello
1 every
1 go
1 let
1 one
1 us
1 world
