any help??

[hkrishnan81]

the function 'getchar' should have a prototype

Or Visual Studio 2012. http://msdn.microsoft.com/en-us/library/6wd819wh.aspx

#include <iostream>
#include <fstream>
#include <string>
#include <cctype>

int main()
{
    const char* const path = "inferno.txt" ;
    const char* const the_word = "the" ;

    // the constructor opens the file, and the destructor will close it
    std::ifstream fin(path) ;

    int count = 0 ;

    // you have #include <string>, why not use std::string
    std::string this_word ;

    // while(!fin.eof()) // this is a wrong idiom
    // instead, check for success *after* the attempted input
    while( fin >> this_word )
    {
        // convert this word to all lower case
        for( char& c : this_word ) // for each character in this word
            c = std::tolower(c) ; // http://en.cppreference.com/w/cpp/string/byte/tolower

        if( this_word == the_word ) // std::string is EqualityComparable
            ++count ;
    }

    std::cout << count << '\n' ;
}

As for your second doubt, its easy. Just check if a character is the newline character('\n') and if it is, then input from file again the next character to check if it's 'p'.

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

void main()
{
	ifstream fin;
	fin.open("inferno.txt", ios::in);

	if(!fin)
	{
		cout << "No such file in directory!" << endl;
		getchar();
		return -1;
	}

	char ch;
	int count = 0;
	while(fin.get(ch))
	{
		if(ch == '\n')
		{
			fin.get(ch);
			if(ch == 'p')
				count++;
		}
	}
	
	cout << count << endl;
	
	getch();
}

NOTE: The above code is for pre ANSI users only

You have absolutely no evidence to conclude either that hkrishnan81 is not using a current compiler or that if he were using one, he would be averse to moving to a later version. Or for that matter, that his institution 'still insists Turbo or something like that'.

If you can't help, just shut up and get out.

I am sorry that I said that. But I didn't really meant to hurt anyone or be offensive. I'll try to be more careful next time before posting.

But I did try to help him(I've posted two full codes for his convenience).

Again SORRY for such comments and this won't happen again.
I apologize.

Fair enough.

Newbies making a genuine effort to learn C++, and coming here expecting help, need all the encouragement and support that they can get. They need to be treated differently from forum veterans.
