-When the integer overflow does trigger an exception show how the exception is catched.
+When the integer overflow does trigger an exception show how the exception is caught.
 When the integer overflow produces some value print it.
 It should be explicitly noted when an integer overflow is not recognized and the program continues with wrong results.
 This should be done for signed and unsigned integers of various sizes supported by the language.
