Here's the code:
#include <iostream>
#include <string>
#include <algorithm>
using namespace std;
int main()
{
string word="";
getline(cin,word);
word.erase(remove_if(word.begin(), word.end(), isspace), word.end());
word.erase(remove_if(word.begin(), word.end(), ispunct), word.end());
word.erase(remove_if(word.begin(), word.end(), isdigit), word.end());
}
When compiled in VS 2010, it works perfectly fine. Compiled with G++ it says:
hw4pr3.cpp: In function `int main()':
