Simple C++ method question (overloading?)

[zeion]

Hi,

If I have a method that takes in say 5 new variables and assigns 5 class variables to these new values, and I only wanted to change one of these variables, is it possible to reuse this method and only have it take in say 1 new variable and change one class variable without having to write different methods for changing each individual variable?

ie.

class testClass
{
void changeFive (int first, second, third, fourth, fifth)
{
testClassFirst = first;
testClassSecond = second;
...
}

void changeOne (int first)
{
testClassFirst = first;
}
}

Two different methods can share the same name (overloading), but other than a common name, they are different methods.

void changeOne (int first)
{
   testClassFirst = first;
}

}

Assuming the 5 class variables are all int, this should work.

void changeVar(int *pl, int r)
{
       *pl = r;
}

You would call it as

changeVar(&testClassFirst, first);
changeVar(&testClassSecond, second);

etc

Though I am not sure how this helps you.

You can write it like this

class testClass
{
void changeFive (int first, second, third, fourth, fifth)
{
testClassFirst = first;
testClassSecond = second;
...
}

void changeFive (int first)
{
testClassFirst = first;
}

void changeFive (int first, int second)
{
testClassFirst = first;
}

void changeOne (int first)
{
testClassFirst = first;
}

void changeOne (int first)
{
testClassFirst = first;
}

phiby's suggestion of using the following is where I would go
void changeVar(int *pl, int r)
{
*pl = r;
}

Yes, it is possible to reuse the same method and only change one class variable by using method overloading in C++. Method overloading allows you to define multiple methods with the same name but different parameter lists. In this case, you can create a new method called "changeOne" and have it take in only one parameter, while the original "changeFive" method remains unchanged. This way, you can call either method depending on your needs, without having to write separate methods for each individual variable. This is a useful feature in C++ that allows for more efficient and organized coding.
