I have written this short piece of code to try out std::sort()
function.
#include <vector>
#include <iostream>
#include <algorithm>
using namespace std;
int main()
{
vector<string> lines;
lines.push_back("apple");
lines.push_back("mango");
lines.push_back("bat");
lines.push_back("cake");
lines.push_back("acid");
lines.push_back("brick");
lines.push_back("base");
vector<string>::iterator itr;
cout << "Before sorting" << endl;
int i = 0;
for (itr = lines.begin(); itr != lines.end(); itr++) {
cout << i << ") " << *itr << endl;
i++;
}
cout << endl;
std::sort (lines.begin(), lines.end());
cout << "After sorting" << endl;
i = 0;
for (itr = lines.begin(); itr != lines.end(); itr++) {
cout << i << ") " << *itr << endl;
i++;
}
}
This runs fine when I compile using g++ on Linux. Here is the output:
$ ./a.out
Before sorting
0) apple
1) mango
2) bat
3) cake
4) acid
5) brick
6) base
After sorting
0) acid
1) apple
2) base
3) bat
4) brick
5) cake
6) mango
But if I try to compile this on Visual Studio 2005, I get an error
like this:
1>main.cpp
1>./src/main.cpp(24) : error C2679: binary '<<' : no operator found
which takes a right-hand operand of type
'std::basic_string<_Elem,_Traits,_Ax>' (or there is no acceptable
conversion)

1> [
1> _Elem=char,
1> _Traits=std::char_traits<char>,
1> _Ax=std::allocator<char>
1> ]
Line 24 is this line: cout << i << ") " << *itr << endl=
