    That's because GNU GCC-C++ (aka g++) doesn't accept "iostream.h" syntax.
    Just use <iostream>

    add this line
    using namespace std;
    below [HASHTAG]#include[/HASHTAG] <iostream>

    It should look something like
    #include <iostream>
using namespace std;

int main()
{
cout << "CrazyEngineers";
}
    If this too fails, then you might've made some mistake in installing compiler.
    Re-installing libstdc++-dev and g++-multilib can fix it.
