Exception handling to detect input string vs. int  C++ 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       #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; }

Exception handling to detect input string vs. int  C++

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

#include <string>
#include <iostream>

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;
