This is what the output should look like.I've been given main but nothing else. I need help with the supporting .cpp files for each of the .h files. I have three .h files(invalidHr, invalidMin and invalidSec)

Write a program that prompts the user to enter time in 12-hour notation.

The program then outputs the time in 24-hour notation. Your program

must contain three exception classes: invalidHr, invalidMin, and

invalidSec. If the user enters an invalid value for hours, then the program

should throw and catch an invalidHr object. Similar conventions for the invalid values of minutes and seconds.

 Given: #include #include #include "invalidHr.h" #include "invalidMin.h" #include "invalidSec.h" using namespace std; int getHours(); int getMinutes(); int getSeconds(); void print24HourTime(int hr, int min, int sec, string str); int main () { int hours; int minutes; int seconds; string str; hours = getHours(); minutes = getMinutes(); seconds = getSeconds(); cout > str; cout > hr; cout  12) throw invalidHr(); done = true; } catch (invalidHr hrObj) { cout > min; cout  59) throw invalidMin(); done = true; } catch (invalidMin minObj) { cout > sec; cout  59) throw invalidSec(); done = true; } catch (invalidSec secObj) { cout
