#includeIn this example, we create a vector of integers and try to access the fourth element using the 'at()' method. Since the vector has only three elements, this will result in an out_of_range error. We catch this error using a try-catch block and print an error message to the console using 'std::cerr'. The package library used in this example is the Standard Template Library (STL), which provides a collection of classes and functions that implement many common data structures and algorithms in cpp.#include #include int main() { std::vector v = {1, 2, 3}; try { int x = v.at(3); std::cout << x << std::endl; } catch (std::out_of_range& e) { std::cerr << "Out of range error: " << e.what() << std::endl; } return 0; }
