Is using goto a bad practice

Hi Kevin,

The problem that you mentioned above can be very easily circumvented by defining a
unique identifier (e.g. a class), and then throwing that. I have rewritten
the code below to show what I mean :

#include <iostream>
using namespace std;

const int asize = 5;

namespace {
	class unique{
	} jump;
};

int main(void)
{

	//Method 1 - using goto to exit double for loop
	for(int row = 0; row < asize; ++row){
		for(int col = 0; col < asize; ++col){
			cout<<"row = "<<row<<", col = "<<col<<endl;
			if(row==2 && col==2){ 
				goto escape;
			}
		}
	}
escape :
	cout<<"Finished method 1\n";

	//Method 2 - using throw and catch to exit double for loop
	int escape=0;

	try{
		for(int row = 0; row < asize; ++row){
			for(int col = 0; col < asize; ++col){
				cout<<"row = "<<row<<", col = "<<col<<endl;
				if(row==2 && col==2){ 
					throw jump;
				}
			}
		}
	}catch(unique){}
	cout<<"Finished method 2\n";

	system("pause");
	return(0);
}
