- 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 419894.2696446.qx3zqy7 #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;}arrow_forwardPARTICIPATION ACTIVITY Arrange the following lines to make a program that determines when the number of people in a restaurant equals or exceeds 10 occupants. The program continually gets the number of people entering or leaving the restaurant. Ex: 2 means two people entered, and -3 means three people left. After each input, the program outputs the number of people in the restaurant. Once the number of people in the restaurant equals or exceeds 10, the program exits. If an Input MismatchException exception occurs, the program should get and discard a single string from input. Ex: The input "2 abc 8" should result in 10 occupants. Not all lines are used in the solution.
