C++ Programming Code Examples C++ > For Loops and While Loops Code Examples Exception in for_each in C++ programming Exception in for_each in C++ programming If the function throws an exception then for_each will also throw the same exception and will break/terminate the loop. Below is an example for the exception case. #include #include using namespace std; void fun1(int x) { cout << x << " "; if (x % 2 == 0) { throw 100; } } struct Class1 // object type function { void operator() (int x) { cout << x << " "; if (x % 2 == 0) { throw 100; } } } myobject; int main() { vector v1; v1.push_back(11); v1.push_back(23); v1.push_back(4); v1.push_back(13); try { for_each(v1.begin(), v1.end(), fun1); } catch (int i) { cout << endl << "Got exception...Value thrown is " << i << endl; } try { for_each (v1.begin(), v1.end(), myobject); } catch (int i) { cout << endl << "Got exception...Value thrown is " << i << endl; } return 0; }
