Question

s 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;
}

return 0;
}
