Need help with I/O streams.......

[Damien]

I have the code for creating an a file strem and printing each word....

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

int main ()
{

string s;
cout<<"enter a file:";
cin>>s;
ifstream dictionary (s.C_str());
if (!dictionary)
return-1;
while(dictionary>>s)
cout<<s<<'/n';
}

Now i have a question. That program displays the words from a file, but how
do i display the words from the file all in lowercase. Like if a word New
York would appear as new york. Can someone please help me out? Thankyou

you have to convert the string to uppercase before displaying it. You
can use the std::transform algorithm to the do job, using the toupper()
function:

#include <algorithm>
#include <cctype>

std::transform(s.begin(), s.end(), s.begin(),
static_cast < int(*)(int) > (toupper));
