Is there a way in C++ to handle unexpected errors? Other languanges I have learned tend to allow this but for some reason I cannot get the try/catch solution to work in all cases. Take the following example:
int main(){
vector<int> v;
try{
//next line should cause an assertion failure.
cout << v[1];
} catch (...) {
cout << "An error has occurred.";
}
return 0;
}In this example, executing the bad line of code within the try block is useless. Is there a better way?
I understand that it is bad practice to mask errors which should be fixed, but the issue is that I am developing a re-useable user interface which I want to include its own error handling classes and methods to handle code which will be integrated with it at a later date. Obviously I have no guarantee that the code which will be integrated into my own will be error free, so I would like to have some functions to provide useful data to help the user determine where the error is.
Help is much appreciated.
