I need to write a program that


a. takes a text file as input (i know i can use fopen with this)

b. modifies the contents of the text file and creates a separate file (it means i have to have another file, the formatted one and must have a different filename) with the ff features
- all words at the start of the sentence should be capitalized.
- additional blank spaces should be removed.

c. also prints the statistics in the text of the number of characters, words and sentences. (i have a knowledge here... i must have a counter for each...)


please help me... thanks![/font=Arial][/size=3][/size=1]

yeah you could use fopen to open the file, fgetc to read charcters from, do what ever with, then use fprintf to create and copy the orginals files changed contents. make sure to use fclose to view new file

Here is a File handling programme might be of your interest.
It contains a program that is given as command parameter the name of a text file, say, temp.dat. It will read each line of temp.dat and print out in correspondence the number of characters and words on that line. At the end it will print out the number of lines that were read....

#include <stdio.h>


int main (int argc, char *argv[]){
  FILE *fp;
  int nchars, nwords, nlines;
  int lastnblank; /* 0 iff the last character was a space */
  char c;


  if(argc!=2){
    printf("Usage: %s filename\n", argv[0]);
    exit(0);
  }
  if((fp=fopen(argv[1],"r"))==NULL){
    perror("fopen");
    exit(0);
  }
  nchars=nwords=nlines=lastnblank=0;
  while((c=getc(fp))!=EOF){
    nchars++;
    if (c=='\n'){
      if (lastnblank)
 nwords++;
      printf("words=%d, characters=%d\n", nwords, nchars);
      nchars=nwords=lastnblank=0;
      nlines++;
    }else{
      if (((c==' ')||(c=='\t'))&(lastnblank))
 nwords++;
      lastnblank=((c!=' ')&&(c!='\t'));
    }
  }
  printf("lines=%d\n", nlines);
  fclose(fp);
}
