Why we use exception in cpp and java?

Answer 1

Sometimes errors can occur like when a program converts a String to an Integer (Word to a Number)
if the String is "1" it can be translated to 1
but if String is "Apple" it cannot be converted to a number, thus it would throw an Exception (error)

So we use try and catch to monitor that everything is working how it should.
