    Exceptions "try, catch, and throw Statements" ???

    Hi all, I wanted to create a program that will tell me how items I can push onto a string vector before the computer runs out of memory and crashes. Now I remember at uni we touched on Exceptions. And I think that that is what I need to be using. But I cant remember how to use them… below I have what I have tried to do so far, but it doesn’t seem to work.


    Code:
    vector<string> wordlist;
    unsigned long long int count = 0;
    try{
        for(;;){
            wordlist.push_back("wordblahhello");
            count++;
            throw count;
        }
    }
    catch(unsigned long long int count){
        cout << count << endl;
    }

    I suspect that it should be something like this:
    Code:
    vector<string> wordlist;
    unsigned long int count = 0;
    try {
        for (;;) {
            wordlist.push_back("wordblahhello");
            ++count;
        }
    }
    catch (const std::bad_alloc& e) {
        cout << count << endl;
    }

If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.
