c++ array of pointers, exceptions and try catch block of nested if statements

Need help with an exception class, currently have some errors such as too many initializers for *Ship[0] and C++ forbids comparison between pointer and integer.

here's what I have in my main that i'm working on figuring out where I'm having issues:

const int ARRAY_SIZE = 6;

Ship *ships[ARRAY_SIZE];

//try catch block

//ship name and information

for (int loop = 0; loop < ARRAY_SIZE; loop++)

{

try

{

if(ships == 0)

{

//ship - name, year, speed

Ship *ships[0] = {new Ship("name of ship", "2018", 17)};

}

if(ships == 1)

{

//cruiseship - name, year, speed, max passengers, decks

ShipArray *ships[1] = new Cruiseship("cruiseship", "2015" ,18, 3000, 26);

}

if (ships == 2)

{

//cargoship - name, year, speed, max tonnage

ShipArray *ships[2] = new Cargoship("Cargo ship", "1700", 23, 2896);

}

if(ships == 3)

{

//ship - name, year, max speed

ShipArray *ships[3] = new Ship("Ship", "1980", 14);

}

if(ships == 4)

{

//cruiseship - name, year, speed, max passengers, decks

ShipArray *ships[4] = new Cruiseship("Cruiseship 2", "2020" , 23, 50000, 80);

}

if (ships == 5)

{

//cargoship - name, year, speed, max tonnage

ShipArray *ships[5] = new Cargoship("Cargo 2", "2020", 17, 877874);

}

}

catch(Cruiseship::NegativeDecks exception)

{

cout << "Error: " << exception.getValue() <<

" is an invalid number of decks for " <<

shipName << "!" << endl;

}

catch(Cruiseship::NegativePassengers exception)

{

cout << "Error: " << exception.getValue() <<

" is an invalid number of passengers for " <<

shipName << "!" << endl;

}

catch(Ship::NegativeSpeed exception)

{

cout << "Error: " << exception.getValue() <<

" is an invalid speed for " <<

shipName << "!" << endl;

}

}
