Catch 22 at cin

entz · 03-28-2007, 04:15 AM

After dedicating a full time for this Catch 22 , I got the remedy to the problem.
googling , testing ,testing ,testing and testing Is the ultimate recipe in this business (and most definitly in any other field as well)
Hell , This is C++ programming ! you either fire up your compiler and probe the code or you can just rename your title to anything else than a "coder"

well , someone before just asked me to giving him a note when I find a smarter solution .

wait , should i license that?? ....nah no need...
So here it's , have fun and educate yourselves! :

Code:

#include <iostream>
using namespace std;

int main(){
	char x[10];
	
	for(;;)
	{
		cout<<"Enter Message:";
		cin.getline(x,10);
		if(cin.fail()){
			cin.clear();
                        //I'm the magic line 
			cin.ignore(std::numeric_limits<std::streamsize>::max(),'\n');
		}
		cin.clear();
		cout<<"Message is:"<<x<<endl;
	}
	return 0;
}

according to the 2003 standard update (and how i hate them)

Edit:
Ooops , someone else just post this before me , should have clicked "post" quicker LOL

Actually it was you who asked...

The important point is that the code was doing what it should. Because you wanted a different behaviour it was necessary to tell the stream to ignore the remaining characters.

I'm glad that you managed to find a solution so that your code will behave the way you want it to.
