❔ (Very beginner)

Guys, I've got a class TvProgram(The program it self), and a class TvWeek(the programs in the week), the class TvWeek consists of a maximum of 100 programs, now I need to make a method that adds a program to the week and adds the amount of the current amount of programs in that week by 1. How do I do that?

    internal class TvWeek
    {
        private TvWeek()
        {
            TvProgram[] arrProg = new TvProgram[100];
        }
        private int current;
        public void TvProgramAdd(TvProgram Program)
        {
            arrProg[current++] = Program;
        }
    }
}

    internal class TvWeek
    {
        private TvWeek()
        {
            TvProgram[] arrProg = new TvProgram[100];
        }
        private int current;
        public void TvProgramAdd(TvProgram Program)
        {
            arrProg[current++] = Program;
        }
    }
}

Use a list instead

Str1keOP•2y ago

We didn't learn lists yet I need to do it somehow without

phaseshift•2y ago

Well arrays are fixed size

Str1keOP•2y ago

Yes It doesn't need to go beyond 100

phaseshift•2y ago

Ok. So what's wrong with what you have?

Str1keOP•2y ago

Str1keOP•2y ago

it doesn't see the arrProg from the TvWeek

phaseshift•2y ago

Paste text not images please

Str1keOP•2y ago

Compiler Error CS0103 - The name 'identifier' does not exist in the current context

phaseshift•2y ago

Why do you think that is? Where did you define it?

Str1keOP•2y ago

I defined it in the class

phaseshift•2y ago

Nope Kinda, but nope

Str1keOP•2y ago

xd, if I define it in another method it won't see it in another? Even tho it's in the same class?

phaseshift•2y ago

Correct

Str1keOP•2y ago

mhmm, so It's only possible to do this question by making a new array in the new method?

phaseshift•2y ago

No

Str1keOP•2y ago

Because it feels kinda strange

phaseshift•2y ago

Look how you defined current

Str1keOP•2y ago

Yes I don't get it

phaseshift•2y ago

What's the difference between that and your array?

Str1keOP•2y ago

Good question

phaseshift•2y ago

You can't see any difference?

Str1keOP•2y ago

I can see a difference I defined the TvWeek and didn't the " current"

phaseshift•2y ago

You did

Str1keOP•2y ago

I didn't encounter questions like this with arrays before So I have hard time understand what's wrong with how I defined the TvWeek

phaseshift•2y ago

It's nothing to do with arrays It's basic c# syntax Where is current defined?

Str1keOP•2y ago

in " internal class TvWeek "

phaseshift•2y ago

Right. In the class body Notice the compiler is not complaining about the use of current in your method

Str1keOP•2y ago

ohh $code

namespace PrepForExam
{
    internal class TvWeek
    {
            TvProgram[] arrProg = new TvProgram[100];

        private int current;

        public void TvWeekAddProgram(TvProgram Program)
        {
            arrProg[current++] = Program;
            
        }
    }
}

namespace PrepForExam
{
    internal class TvWeek
    {
            TvProgram[] arrProg = new TvProgram[100];

        private int current;

        public void TvWeekAddProgram(TvProgram Program)
        {
            arrProg[current++] = Program;
            
        }
    }
}

but they say, that TvWeek has two parameters - array in a length of 100 TvPrograms and current in int Is that considered a parameter of the class TvWeek?

phaseshift•2y ago

Parameters are inputs to methods (including constructors)

Str1keOP•2y ago

So that's not a parameter You know how can I make it a parameter and use it in the class?

phaseshift•2y ago

Look up constructors

Str1keOP•2y ago

Yes

phaseshift•2y ago

You pass in arguments, then assign the value to class fields

Str1keOP•2y ago

 public TvWeek(TvProgram[] arr)
        {
            
        }

 public TvWeek(TvProgram[] arr)
        {
            
        }

I do this, and then I send array of 100 programs?

phaseshift•2y ago

Yes And save the value to a field

Str1keOP•2y ago

Can you please explain that?

phaseshift•2y ago

Ie you still need arrProg

Str1keOP•2y ago

Oh, so define this array as arrProg in the constructor?

phaseshift•2y ago

No Probably best if you look up constructors

Str1keOP•2y ago

I will check it, but I did work with constructors, just not arrays

phaseshift•2y ago

Again, your questions are not any difficulty to do with arrays

Str1keOP•2y ago

You right Ohhh, I see now

    internal class TvWeek
    {
        private TvProgram[] arrProg;
        public TvWeek()
        {
            arrProg = new TvProgram[100];
        }

        private int current;

        public void TvWeekAddProgram(TvProgram Program)
        {
            arrProg[current++] = Program;
            
        }
    } 
}

    internal class TvWeek
    {
        private TvProgram[] arrProg;
        public TvWeek()
        {
            arrProg = new TvProgram[100];
        }

        private int current;

        public void TvWeekAddProgram(TvProgram Program)
        {
            arrProg[current++] = Program;
            
        }
    } 
}

I had to write it that way, thank you for your time!
