The inclusion of iostream breaks the following program. A workaround is to define an inline function that calls into tolower() and use it as the last argument to transform().
Code:
#include <cctype>
#include <string>
#include <algorithm>
#include <iostream>
int main()
{
std::string foo("AbCd");
std::transform(foo.begin(), foo.end(), foo.begin(), std::tolower);
return 0;
}
Output:
