Explanation / Answer

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

using namespace std;

void func(const string& word)
{
//set field width
cout.width(30);
cout << left << word << " " << word.size() << endl;
}

int main(int argc, char* argv[])
{
ifstream ifs("F:\tmp\test.txt");
if(ifs.fail())
{
cout << "fail to open file" << endl;
return -1;
}

_Ctypevec ct = _Getctype();
for(char ch = 0; ch < SCHAR_MAX; ch++)
{
//set all punctuations as field separator of extraction
if(ispunct(ch))
{
(const_cast<short*>(ct._Table))[ch] = ctype<char>::space;
}
}

//change the default locale object of ifstream
ifs.imbue(locale(ifs.getloc(), new ctype<char>(ct._Table)));

string word;
while(ifs >> word)
{
func(word);
}

ifs.close();
}
#include <iostream>
#include <string>
#include <fstream>
using namespace std;

void printString( const string & str ) { // ignore the & for now, you'll get to it later.
cout << str << " : " << str.size() << endl;
}

int main() {
ifstream fin("your-file-name.txt");

if (!fin) {
cout << "Could not open file" << endl;
return 1;
}

string word; // You only need one word at a time.
while( fin >> word ) {
printString(word);
}

fin.close();
}
