Question

In C++, Write a program to read in a simple text file (let's call it "simplefile.txt") and:
find the number of characters in each word (save those values as a variable called "word"), the number of characters in each line (save those values as a variable called "line"), the number of characters in each sentence (save those values as a variable called "sent"), and the number of characters in each paragraph (save those values as a variable called "para").Please make the program as simple as possible and include comments illustrating the logic behind each step.

Explanation / Answer

#include<iostream.h>
#include<fstream.h>
#include<string.h>
#include<conio.h>
#include<stdio.h>

void countchar(char *filename)
{
   ifstream fin(filename);   
   char ch;
   std::string line;
   int i,words=0,sent=0,lines=0;
   int wc=0, lc=0, sc=0;
   bool l=false, s=false;
   while(fin.get(ch))
   {
       i=ch;
       //cout<<ch;
              
       if(i==' ')
       {  
           words++;
           cout << " word no "<<words<<" contains "<<wc<<" characters"<<endl;
           wc=0;
       }
       else if (i == ' ')
       {
           // check if sentence is complete then count only line and not words
           if(!s)
           {
               words++;
               cout << "Word no "<<words<<" contains "<<wc<<" characters"<<endl;
               wc=0;
              
           }
          
           lines++;
           cout << "Line no "<<lines<<" contains "<<lc<<" characters"<<endl;
           lc=0;
           s=true;
       }
       else if (i == '.') // if character is . this marks end of sentence so display characters in sentence
       {
           words++;
           cout << " word no "<<words<<" contains "<<wc<<" characters"<<endl;
           wc=0;
          
           sent++;
           cout << "Sentence no "<<sent<<" contains "<<sc<<" characters"<<endl;
           sc=0;
           s=true;
      
          
       }
       else
       {
           wc++; lc++; sc++;
       }
      
  
   }
   fin.clear();
  

}
int main()
{

char *filename="sent.txt";
char a;
countchar(filename);
return 0;
getch();
}

// Regarding paragraph, it depends on how you view paragraph. Isit new line or one empty line in between. Usually paragraphs start in new line so in that case.
