Exception handling in C++ is a mechanism that allows a program to handle errors or exceptional situations during runtime by using try, catch, and throw statements.
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...

the throw exception creates a temporary object of class type pushOnFull by calling the class constructor An exception object of type pushOnFull is created to be passed to the exception handler. The exception object is is a copy of the temporary object created by the throw expression in step ...
