Thread: best way to do this?

Just wondering if this is the best / Cleanest way to write this code.

Code:

#include <iostream>

using namespace std;

int Multiplier(int AmountToMultiply);

int main()
{

	int input;
	int Result = 0;

	cout << "Enter Cat or Dogs age: ";
	cin >> input;

	Result = Multiplier(input);

	cout << "\nYour animal is: " << Result << endl;

	system("PAUSE");
	return 0;
}

int Multiplier(int Amount)
{
	return Amount * 7;
}

also, if i was to make a amount.h file which only contains

Code:

int Multiplier(int Amount)
{
	return Amount * 7;
}

and remove that part from the main code and add #include "Amount.h" would it still work?

Yes, but it's a lot of work for something so tiny, and it definitely doesn't need its own header file:

Code:

#include <iostream>

int main () {
     int dog_age = 0;
     std::cout << "Enter dog's age: ";
     std::cin >> dog_age;
     std::cout << "Your animal is " << dog_age * 7 << "\n";
     return 0;
}

If you have a lot of Dogs or something you can make it a class so that you can build an array, and have the constructor compute the age.

lol yeh i know its big and no need for a header but im learning.

i was just testing out a function for it. but would it work by doing it with the header i said? im not going to, just want to know as im getting used to using functions and headers.

cheers. Hugo.

heres another thing that will not work...

its of a book im readin and it wont work. the error is below it.
sorry to keep asking.

Code:

// demonstrates the use of default parameters

#include <iostream>

using namespace std;

int AreaCube(int Length, int Width = 25, int Height = 1);

int main()
{
	int Length = 100;
	int Width = 50;
	int Height = 2;
	int Area;

	Area = AreaCube(Length, Width, Height);
	cout << "First area equals: " << Area << "\n";

	Area = AreaCube(Length, Width);
	cout << "Second area equals: " << Area << "\n";

	Area = AreaCube(Length);
	cout << "Third area equals: " << Area << "\n";
	system("PAUSE");
	return 0;
}

AreaCube(int Length, int Width, int Height)

{
	return (Length * Width * Height);
}

hugo.

You missed an 'int' before 'AreaCube'.

lmao how the hell did i miss something as small as that

thanks alot mate. hugo.
