"for everyone" is not a member of std. C ++ 11 support is already included

The code for my homework for the teacher is as follows. This is right out of the box, I have not changed the code of my professor. The program has more, but an error occurs here. The problem line is in bold.

std::cout << "\nAll remaining courses with enrollments:\n";
allCourses = WSUCourse::getAllCourses();
std::for_each(
  allCourses.begin(),
  allCourses.end(),
  WSUCoursePrinter());

I get the following error.

g++    -c -g -std=c++11 -MMD -MP -MF "build/Debug/Cygwin_4.x-Windows/main.o.d" -o build/Debug/Cygwin_4.x-Windows/main.o main.cpp

       std::cout << std::to_string(studentPtr->getUniqueID()) <<

To summarize, this is exactly the same as the name. "'For each' is not a member of std" I have already included standard 11 support in the entire IDE in which I compiled it. In blocks of code, I put the argument in the compiler options, in netbeans I changed it in the project properties on the compiler, even the Linux system on the school network won’t run it with the same error, and I used the standard inclusion line 11.
