C# using the "this" keyword in this situation?
- by Alex
Hi,
I've completed a OOP course assignment where I design and code a Complex Number class. For extra credit, I can do the following:
Add two complex numbers. The function will take one complex number object as a parameter and return a complex number object. When adding two complex numbers, the real part of the calling object is added to the real part of the complex number object passed as a parameter, and the imaginary part of the calling object is added to the imaginary part of the complex number object passed as a parameter.
Subtract two complex numbers. The
function will take one complex
number object as a parameter and
return a complex number object. When
subtracting two complex numbers, the
real part of the complex number
object passed as a parameter is
subtracted from the real part of the
calling object, and the imaginary
part of the complex number object
passed as a parameter is subtracted
from the imaginary part of the
calling object.
I have coded this up, and I used the this keyword to denote the current instance of the class, the code for my add method is below, and my subtract method looks similar:
public ComplexNumber Add(ComplexNumber c)
{
double realPartAdder = c.GetRealPart();
double complexPartAdder = c.GetComplexPart();
double realPartCaller = this.GetRealPart();
double complexPartCaller = this.GetComplexPart();
double finalRealPart = realPartCaller + realPartAdder;
double finalComplexPart = complexPartCaller + complexPartAdder;
ComplexNumber summedComplex = new ComplexNumber(finalRealPart, finalComplexPart);
return summedComplex;
}
My question is: Did I do this correctly and with good style? (using the this keyword)?
