How to count characters from text file ….counting number of character occured from a file(txt)..line by line

please

If you just want to count all the characters , you can do:
 

C

#include<stdio.h><br /> #include <string.h><br /> int main(void)<br /> {<br />  // open a text file for reading<br />  FILE * in_file;<br />  in_file = fopen("c:\programs\help\text1.txt","r");<br />  <br /> <br />  if ( ! in_file  )<br />  {<br />   printf ( "file did not openn" );<br />   return 1;<br />  }<br />     int numberOfCharacters = 0;<br />  char ch = fgetc ( in_file );<br />  while ( ch != EOF )<br />  {<br />         numberOfCharacters ++;<br />         ch = fgetc ( in_file );<br />  }<br />  printf ( "nthe number of characters is " );<br />  printf ( "%i" , numberOfCharacters );<br />  fclose ( in_file );<br />     return 0;<br /> }

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

#include<stdio.h><br /> #include <string.h><br /> int main(void)<br /> {<br />  // open a text file for reading<br />  FILE * in_file;<br />  in_file = fopen("c:\programs\help\text1.txt","r");<br />  <br /> <br />  if ( ! in_file  )<br />  {<br />   printf ( "file did not openn" );<br />   return 1;<br />  }<br />     int numberOfCharacters = 0;<br />  char ch = fgetc ( in_file );<br />  while ( ch != EOF )<br />  {<br />         numberOfCharacters ++;<br />         ch = fgetc ( in_file );<br />  }<br />  printf ( "nthe number of characters is " );<br />  printf ( "%i" , numberOfCharacters );<br />  fclose ( in_file );<br />     return 0;<br /> }

Count each line, voila: (you can pass the filename/path as the first argument)

C

#include <stdio.h><br /> <br /> int main(int argc,char **argv)<br /> {<br /> const int max=1024;<br /> int r=0,count=0,i;<br /> FILE *f;<br /> char buff[max+3];<br /> <br /> if (argc==2)<br /> {<br /> if ((f=fopen(argv[1],"rb"))==NULL)<br /> {<br /> r=2;<br /> printf("cannot open file!n");<br /> }<br /> else<br /> {<br /> while (!feof(f))<br /> {<br /> buff[0]=0;<br /> fgets(buff,max,f);<br /> count++;<br /> <br /> for (i=0;i<max &#038;&#038; buff!=0 &#038;&#038; buff!='r' &#038;&#038; buff!='n';i++);<br></max> <br /> printf("Line %i, count %in",count,i);<br /> }<br /> <br /> fclose(f);<br /> }<br /> }<br /> else<br /> {<br /> r=1;<br /> printf("usage: count <file>n");<br /> }<br /> <br /> return r;<br /> }</file>

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40

#include <stdio.h><br /> <br /> int main(int argc,char **argv)<br /> {<br /> const int max=1024;<br /> int r=0,count=0,i;<br /> FILE *f;<br /> char buff[max+3];<br /> <br /> if (argc==2)<br /> {<br /> if ((f=fopen(argv[1],"rb"))==NULL)<br /> {<br /> r=2;<br /> printf("cannot open file!n");<br /> }<br /> else<br /> {<br /> while (!feof(f))<br /> {<br /> buff[0]=0;<br /> fgets(buff,max,f);<br /> count++;<br /> <br /> for (i=0;i<max &#038;&#038; buff!=0 &#038;&#038; buff!='r' &#038;&#038; buff!='n';i++);<br></max> <br /> printf("Line %i, count %in",count,i);<br /> }<br /> <br /> fclose(f);<br /> }<br /> }<br /> else<br /> {<br /> r=1;<br /> printf("usage: count <file>n");<br /> }<br /> <br /> return r;<br /> }</file>
