Is CodeBlocks being stupid or the code?

I build and run this and it says "EOF has not been declared" at line 19......... I typed the exact codes one by one.

First: How do you type the EOF?
Second: EOF is not defined in your program anywhere.
Third: EOF stands for End Of File, where is your file?
Fourth: There is a few predefined EOF's but I'm not sure you want any of them for this.

Edit: Ignore the first comment, it's possible, but I still don't believe that's what you want.

You could try using while ((grade = cin.get()) != '\n')

Try while(std::cin>>grade)
