Question

Hello , what is used in specification in cpp

Answer 1

I hope you mark my answer as brainlist..☺️

C++ provides a mechanism to ensure that a given function is limited to throw only a specified list of exceptions. An exception specification at the beginning of any function acts as a guarantee to the function's caller that the function will throw only the exceptions contained in the exception specification.

For example, a function:

void translate() throw(unknown_word,bad_grammar) { /* ... */ }

explicitly states that it will only throw exception objects whose types are unknown_word or bad_grammar, or any type derived from unknown_word or bad_grammar.
