I dont know where to go from here TEMPLATES

/*

#include <iostream>

using namespace std;

what are you having trouble with? we wont do your homework for you

[hoofhamples]

i don't have any homework i am taking text documents from the web to learn c++... anyways i don't quite understand how to use templates yet. I am self taught, so i miss a lot of important things i guess.
So..

/*

*/

#include <iostream>

using namespace std;


template <class integertemplate>
integertemplate totalint (integertemplate integers)
{
	cout << "How many integer values do you wish to total? ";
	cin >> integers;

	for(int i = 0; i < integers; i++;)
	{
	cout << "Please enter an integer:";
	}

	cout << "The total is: " << totalint() <<endl;
	
}
template <class doubletemplate>
doubletemplate totaldouble (doubletemplate doubles)
{
	cout << "How many double values do you wish to total? ";
	cin >> doubles;

	for(int i = 0; i < integers; i++;)
	{
	cout << "Please enter an integer:";
	}

	cout << "The total is: " << totaldouble() <<endl;
}

int main ()
{
	

	system("pause");
	return 0;
}

Is this reasonable?

[Little Bobby Tables]

not at all... you do know the point of templates right?

[hoofhamples]

i believe if i can understand this e-book, (which i doubt) they are used to store multiple values or something, in a single variable without declaring a data type?

[hoofhamples]

#include <iostream>

using namespace std;

template <class integertemplate>
integertemplate add (integertemplate n1, integertemplate n2, integertemplate n3)
{
	integertemplate result;

	result = n1+n2+n3;

	return result;	
}
template <class doubletemplate>
doubletemplate totaldouble (doubletemplate doubles)
{
	
}

int main ()
{
	cout << add(5,5,5);

	system("pause");
	return 0;
}

So i would assume this is a way to get started from a template

[Little Bobby Tables]

no... that is not how you use templates at all... that is an array type deal...
1)dont use using namespace std;
2) i wouldnt end template names with template, cause its a bit redundant.
3) dont use system
4) read this: http://www.cprogramming.com/tutorial/templates.html

[hoofhamples]

Well i read that whole tutorial series, but in my compiler i use system pause as a quick fix, just so i can see the output in cmd. I have gotten pretty far, although why cant i use += to add my results? I assume number is just updating after the next integer is entered in...

#include <iostream>

using namespace std;


template <class integertemplate>
integertemplate add (integertemplate number)
{
	integertemplate result;

	result += number;

	return result;	
}


int main ()
{
	
	int numInts;
	int integerIn;

	cout << "How many integer values do you wish to total: ";
	cin >> numInts;
	for(int i = 0; numInts > i; i++)
	{
		cout << "enter a value: ";
		cin >> integerIn;
	}

	cout << add(integerIn);

	cout << "How many double values do you wish to total: ";


	system("pause");
	return 0;
}

It states uninitialized local variable result is used: even if i initialize it to 0, it still wont print the total. I assume i need to define an array in my template??

Finished!
