C++ program works fine locally but gives me errors when I submit it as homework due to -Wfatalerrors

Title. The program uses parallel arrays and sorts children and parents into sides. The error I'm getting is:
parents.cpp: In function 'int main()':
parents.cpp:37: error: 'class MyStream' has no member named 'ignore'
compilation terminated due to -Wfatal-errors.
and my code is:

Change line 37 to std::cin.ignore();. Not exactly sure what MyStream is
LB (13399)
The code has no compilation errors. Are you sure you are submitting the correct file? There is no mention of "MyStream" in your code. What happens if you change line 37 to std::cin.ignore();?
keltonfan2 (100)
Now I get
parents.cpp: In function 'int main()':
parents.cpp:37: error: '__my_cin' is not a member of 'std'
compilation terminated due to -Wfatal-errors.
with std::cin.ignore();
LB (13399)
Do you know what compiler is being used to verify your assignment? It sounds like someone took GCC and mutilated it.
keltonfan2 (100)
Unfortunately, I have no idea what they're using. Locally I'm using the default compiler in Dev-C++.
LB (13399)
Have you tried talking to your professor or emailing them to find out what's going on? Just copy the errors you are getting and they will probably have a copypaste answer for you.
