How do I break out of multiple loops?

Gregory Sakas (72)
EX: If "myVector" contains a random series of numbers and i have the code:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
 
do
{
    for(count=0;count<myVector.size();count++)
    {
        if(myVector.size()==3)
            //This is where I would want to break out of all of the loops
        else
        {
            ...
        }
        cout << endl;
        ...
        ...
    }
    ...
    ...
}
while(random!=2)


^^The above code is just an example. The "..." just represent random code

you COULD(but by no means should) use a goto statement.

works like this:

1
2
3
4
5
6
7
8
9
10
 
#include<iostream>
using namespace std;

int main{
goto here;
cout << "skip me" << endl;
here:
cout << "I'm here" <<endl;
return 0;
}



I'm here

I was trying to avoid that but I don't see any other way unless I can break out of all the loops

What about this:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23

try{
do
{
    for(count=0;count<myVector.size();count++)
    {
        if(myVector.size()==3)
                   throw 1;
         //This is where I would want to break out of all of the loops
        else
        {
            ...
        }
        cout << endl;
        ...
        ...
    }
    ...
    ...
}
while(random!=2)
}
catch(int a){
//do stuff
}

Almost as unstable as a goto loop
blueberry (130)
What is so unstable about it? Using try catch is very flexible. E.G. if you were to, say, declare dynamic memory inside the loop, you could instead throw a vector of pointers, and then delete the unfreed memory using the pointers in that vector within the catch statement.

Another option would be to make a boolean and have the loop exit when the boolean is false;
Or you could simply put your loop in a function, and return when your condition is met.

You could add an extra condition inside each for/while statement, otherwise goto is probably your best bet. I would argue that goto is better than try/catch since it makes more sense semantically. For an outside reader of your code, the try/catch stuff is going to be confusing because the assumption is that it represents unexpected or unwanted behaviour.
