Show us the code you've written so far.

#include <iostream>
#include <fstream>
#include <string>
#include <sstream>

using namespace std;

int main()
{
string fileName;
char c;
cout << endl;
cout << "Enter the name of the file: ";
cin >> fileName;
cout << endl << endl;

//declares filename
ifstream d_file;
d_file.open(fileName.c_str()); //attempts to open file

if (!d_file.is_open())
{
//if file doesn't exist; don't create a new one
cout << "File " << fileName << " does not exist in the
client's current directory" << endl;
system("pause");
exit(1);
}
else
{
d_file.get(c);
d_file.seekg(0, ios::end);
int charCount = d_file.tellg();
d_file.seekg (0, ios::beg);
//prints the number of characters in a file;
cout << "the number of characters in the " << fileName;
cout << " is " << charCount << endl;

//prints the number of lines in a file
string t;
int lineCount=0;

while(getline(d_file, t, '\n'))
++lineCount;

cout << "The number of lines in the file is " <<
lineCount << endl;

//reads the number of lines in a file, then print
int wordCount=0;
string word;

for (;
{
d_file >> word;
if ( d_file.eof() ) { break;}
wordCount++;
}
cout << wordCount << endl;
}
d_file.close();
system("pause"):
return 0;
}

******
i got the read number of lines and characters in d file worked right
except for the wordCount, it kept on giving me a 0....

That's logical. You open a file, read it until the end to get the line
count, then you try to read on to get the word count. Since you're already
at the end of file, you break out of the loop immediately and the count
stays at 0. Seek to the beginning and restet the stream's eof flag after
the first loop.
