Hence, you cannot throw it using athrowstatement. To throw an out of range exception in C++, you must create an out of range exception by passing a string as an input argument to thestd::out_of_range()constructor; only then will you be able to throw the out of range exception successf...
We can throw an exception of a different type, std::string for example: Copy #include <iostream> #include <string> int main() /* ww w . j a v a2s . c o m*/ { try { std::cout << "Let's assume some error occured in our program." << '\n'; std::cout << "We throw...
