c++ try and catch not ending program - c++

Question

I know this is a lot of code but it's just a program that prompts for speed, altitude, fuel, and direction and catches any errors. If an error is thrown then the program should stop and if there is no error than the program should just display all the values. My problem is that whenever the last try-catch statement(InvalidDirection) catches an error the program still runs the showAll function.
#pragma once
#include <iostream>
using namespace std;
class FlightInfo
{
private:
int absoluteAltitude = 0;
int speed = 0;
int fuelLevel = 0;
int direction = 0;
public:
class InvalidSpeed
{};
class InvalidDirection
{};
class InvalidFuelLevel
{};
class InvalidAltitude
{};
// setters
//valid 0-10000
void setAbsoluteAltitude(int alt) {
if (alt >= 0 && alt <= 10000) {
absoluteAltitude = alt;
}
else {
throw InvalidAltitude();
}
}
//valid 0 - 650
void setSpeed(int currentSpeed) {
if (currentSpeed >= 0 && currentSpeed <= 650) {
speed = currentSpeed;
}
else {
throw InvalidSpeed();
}
}
// Valid 0 - 100
void setFuelLevel(int level) {
if (level >= 0 && level <= 100) {
fuelLevel = level;
}
else {
throw InvalidFuelLevel();
}
}
// valid 0-359
void setDirection(int heading) {
if (heading >= 0 && heading <= 359) {
direction = heading;
}
else {
throw InvalidDirection();
}
}
// getters
int getAbsoluteAltitude() {
return absoluteAltitude;
}
int getSpeed() {
return speed;
}
int getFuelLevel() {
return fuelLevel;
}
int getDirection() {
return direction;
}
void showAll() {
cout <<"Altitude = " << getAbsoluteAltitude() << endl;
cout <<"Speed = " << getSpeed() << endl;
cout <<"FuelLevel = " << getFuelLevel() << endl;
cout <<"Direction = " << getDirection() << endl;
}
};
Here is my driver/cpp file
#include "FlightInfo.h"
#include <iostream>
using namespace std;
int main() {
FlightInfo flight;
int getTheSpeed;
int getTheAltitude;
int getTheFuel;
int getTheDirection;
cout << "Enter Speed ";
cin >> getTheSpeed;
try {
flight.setSpeed(getTheSpeed);
}
catch (FlightInfo::InvalidSpeed)
{
cout << "ERROR: speed less than 0 or greater than 650" << endl;
}
cout << "Enter altitude ";
cin >> getTheAltitude;
try {
flight.setAbsoluteAltitude(getTheAltitude);
}
catch (FlightInfo::InvalidAltitude)
{
cout << "ERROR: Altitude less than 0 or greater than 10000" << endl;
}
cout << "Enter Fuel Level ";
cin >> getTheFuel;
try {
flight.setFuelLevel(getTheFuel);
}
catch (FlightInfo::InvalidFuelLevel)
{
cout << "ERROR: Fuel level less than 0 or greater than 100" << endl;
}
cout << "Enter direction ";
cin >> getTheDirection;
try {
flight.setDirection(getTheDirection);
}
catch (FlightInfo::InvalidDirection)
{
cout << "ERROR: Direction is less than 0 or greater than 359" << endl;
}
flight.showAll();
system("pause");
return 0;
}

Answer 1

The Problem:
Even when the last try-catch statements catch an error the program still runs the showAll function.
The Reason:
None of the catch clauses exits the program.
Possible Solutions:
In every catch clause, put a return <any number other than zero>.
Do not catch the Exceptions.
In every catch clause, put an exit clause.

Answer 2

I am not sure that I see the issue with what you described. Are you expecting when invalid direction is thrown the program does not get to showall()?:
cout << "Enter direction ";
cin >> getTheDirection;
try {
flight.setDirection(getTheDirection);
}
catch (FlightInfo::InvalidDirection)
{
cout << "ERROR: Direction is less than 0 or greater than 359" << endl;
}
flight.showAll();
But here you are "catch"ing the exception and handling it. Therefore the program continues. If you want it to end you will need to re-throw or not catch the exception:
cout << "Enter direction ";
cin >> getTheDirection;
//try {
flight.setDirection(getTheDirection);
//}
//catch (FlightInfo::InvalidDirection)
//{
// cout << "ERROR: Direction is less than 0 or greater than 359" << endl;
//}
flight.showAll();
Now your inner "throw" will not be caught and your program will end.
