Does it matter which compiler I use?

I was working on a homework assignment for my intro programming class and I was using GDB online because it's easier for me to tweak things in that environment.

Once it was all working correctly, I copied the code exactly into Putty, but when I went to compile it I got a bunch of error messages.

Is this a normal thing? I was just using the regular iostream library. We are learning user defined functions. Here's an example of the errors, any help would be greatly appreciated.

cin << entry;

This would generate an on every implementation: cin << entry ;
Should be: cin >> entry ;

Oh good grief, that fixed it. I feel like an idiot.
Thank you for your help!
