How Can I Check Overflows? - I used cin.getline() - C++

Both examples doesn't work. User is expected to insert chars less than MAX_DATA length, but i want to handle the situation when user inserts over MAX_DATA. I tried several examples, non of them worked...
char userInput[MAX_DATA];
               cin.getline(userInput, MAX_DATA);
			cout<<"Overflow occured. Restart Application"<<endl;
               cin.getline(userInput, MAX_DATA);
		if(strlen(userInput) > MAX_DATA)
			cout<<"Overflow occured. Restart Application"<<endl;

Try using:

instead of cin.failbit

failbit is the actual bit, not the state
