$8\mathrm{.}5$ LAB: Exception handling to detect input string vs$.$ int

The given program reads a list of single$-$word first names and ages $($ending with $-1),$ and outputs that list with the age incremented. The program fails and throws an exception if the second input on a line is a string rather than an int. At FIXME in the code, add a try$/$catch statement to catch ios$\_$base::failure, and output $0$ for the age.

Ex: If the input is:

Lee $18$

Lua $21$

Mary Beth $19$

Stu $33$

$-1$

then the output is:

Lee $19$

Lua $22$

Mary $0$

Stu $34$

Default Template $.$cpp:

#include

#include

using namespace std;

int main$()\{$

string inputName;

int age;

$//$ Set exception mask for cin stream

cin.exceptions$($ios::failbit$)$;

cin $>>$ inputName;

while$($inputName $!="-1")\{$

$//$ FIXME: The following line will throw an ios$\_$base::failure.

$//$ Insert a try$/$catch statement to catch the exception.

$//$ Clear cin's failbit to put cin in a useable state.

cin $>>$ age;

cout $<<$ inputName $<<""<<($age $+1)<<$ endl;

cin $>>$ inputName;

$\}$

return $0$;
