Hi,
I used some manipulators in the form of
#include <iostream>
#include <ios>
int main () {
std::cout << std::showbase << std::hex << 100 << std::endl;
}
This compiles fine with g++ 3.x. However, it fails on g++ 2.96
since it cannot find ios. When I remove ios, it cannot find showbase. Then
I change std::showbase to std::ios::showbase, but this showbase is not a
manipulator any more. As a result the program outputs 8064 instead of
0x64.
So my question is: Is there any good coding practice to make sure
that the same code compiles for both and works as intended? Thanks.
