在用DEV-CPP编译以下代码时出错 用VC++6.0则顺利通过 请问是怎么回事?


#include <algorithm>
#include <cctype>
#include <iostream>
#include <iterator>

using namespace std;

int main()
{
char a[] = "asdgafhadfjsgjgfujsrtu";
const size_t sz = sizeof a / sizeof a[0];
transform(a, a + sz, a, toupper);
copy(a, a + sz, ostream_iterator<char>(cout));
cout << endl;
system("PAUSE");
return 0;
}

还有这段代码 凡是带transform的都不行 哪位高手知道怎么回事呀

#include <string>
#include <vector>
#include <fstream>
#include <iostream>
#include <algorithm>
#include <cctype>
#include <iterator>

using namespace std;

string lower(const string& s);

int main()
{
vector<string> words;
typedef vector<string>::iterator vsi;
string word;
ifstream in("E:\\text.txt");
while(in >> word)
{
words.push_back(word);
}
transform(words.begin(), words.end(), words.begin(), lower);
sort(words.begin(), words.end());
vsi it = unique(words.begin(), words.end());
copy(words.begin(), it, ostream_iterator<string>(cout, " "));
system("PAUSE");
}

string lower(const string& s)
{
string ss = s;
transform(ss.begin(), ss.end(), ss.begin(), tolower);
return ss;
}

不能沉下去 ..
