Does this server help with homework?

Hello, I'm new here and I would say that I'm new to C#, but I've been taking this course for about 4 weeks. Yet, I struggle very much with its concepts, I'm doing this assignment and I want to get as much done without looking up how other people have done the same assignment. Does this server allow for help or explanations on things like that?

Does it help with homework? Absolutely, yes. Does it do homework for you? No, not a chance.

Thank you Shall I make a new post dedicated to what I'm struggling with or can it be done here still?

Ok I'm trying to make it so that it asks the user for the base and exponent(power) then print the result

using System;
namespace PowerNumber
{
    class Program
    {
        static void Main(string[] args)
        {
            int PowerFunction(int base, int power)
            {
                if (power != 0) return base * PowerFunction(base, power - 1);
                else return 1;

            }

        }
        Console.Write("Enter the base:");
            base = Convert.ToInt32(Console.ReadLine());

            Console.Write("Enter the second exponent:");
            power = Convert.ToInt32(Console.ReadLine());

            double result = Math.Pow(base, power);
        Console.WriteLine("\n\nThe sum of the two numbers is " + result);
    }

}

using System;
namespace PowerNumber
{
    class Program
    {
        static void Main(string[] args)
        {
            int PowerFunction(int base, int power)
            {
                if (power != 0) return base * PowerFunction(base, power - 1);
                else return 1;

            }

        }
        Console.Write("Enter the base:");
            base = Convert.ToInt32(Console.ReadLine());

            Console.Write("Enter the second exponent:");
            power = Convert.ToInt32(Console.ReadLine());

            double result = Math.Pow(base, power);
        Console.WriteLine("\n\nThe sum of the two numbers is " + result);
    }

}

I want to keep

int PowerFunction(int base, int power)
{
    if (power != 0) return base * PowerFunction(base, power - 1);
    else return 1;

}

int PowerFunction(int base, int power)
{
    if (power != 0) return base * PowerFunction(base, power - 1);
    else return 1;

}

And what is the issue?

AppleCyder (NovaSprite)OP•9mo ago

It doesn't work, I don't know where this should go

 Console.Write("Enter the base:");
     base = Convert.ToInt32(Console.ReadLine());

     Console.Write("Enter the second exponent:");
     power = Convert.ToInt32(Console.ReadLine());

     double result = Math.Pow(base, power);
 Console.WriteLine("\n\nThe sum of the two numbers is " + result);

 Console.Write("Enter the base:");
     base = Convert.ToInt32(Console.ReadLine());

     Console.Write("Enter the second exponent:");
     power = Convert.ToInt32(Console.ReadLine());

     double result = Math.Pow(base, power);
 Console.WriteLine("\n\nThe sum of the two numbers is " + result);

It should go into a method Probably your Main method, as this is the first method that executes And your PowerFunction should be another method of the Program class Unless you did intend it to be a local function Things become more clearer with syntax highlighting and proper formatting:

using System;
namespace PowerNumber
{
    class Program
    {
        static void Main(string[] args)
        {
            int PowerFunction(int base, int power)
            {
                if (power != 0) return base * PowerFunction(base, power - 1);
                else return 1;

            }
        }

        Console.Write("Enter the base:");
        base = Convert.ToInt32(Console.ReadLine());

        Console.Write("Enter the second exponent:");
        power = Convert.ToInt32(Console.ReadLine());

        double result = Math.Pow(base, power);
        Console.WriteLine("\n\nThe sum of the two numbers is " + result);
    }
}

using System;
namespace PowerNumber
{
    class Program
    {
        static void Main(string[] args)
        {
            int PowerFunction(int base, int power)
            {
                if (power != 0) return base * PowerFunction(base, power - 1);
                else return 1;

            }
        }

        Console.Write("Enter the base:");
        base = Convert.ToInt32(Console.ReadLine());

        Console.Write("Enter the second exponent:");
        power = Convert.ToInt32(Console.ReadLine());

        double result = Math.Pow(base, power);
        Console.WriteLine("\n\nThe sum of the two numbers is " + result);
    }
}

As you can see, a good chunk of your code is inside of the class

AppleCyder (NovaSprite)OP•9mo ago

Yeah so I know that it won't work the way I did it Let me think What doesn't match between

int PowerFunction(int base, int power)
{
    if (power != 0) return base * PowerFunction(base, power - 1);
    else return 1;

}

int PowerFunction(int base, int power)
{
    if (power != 0) return base * PowerFunction(base, power - 1);
    else return 1;

}

and

Console.Write("Enter the base:");
    base = Convert.ToInt32(Console.ReadLine());

    Console.Write("Enter the second exponent:");
    power = Convert.ToInt32(Console.ReadLine());

    double result = Math.Pow(base, power);
Console.WriteLine("\n\nThe sum of the two numbers is " + result);

Console.Write("Enter the base:");
    base = Convert.ToInt32(Console.ReadLine());

    Console.Write("Enter the second exponent:");
    power = Convert.ToInt32(Console.ReadLine());

    double result = Math.Pow(base, power);
Console.WriteLine("\n\nThe sum of the two numbers is " + result);

Angius•9mo ago

What do you mean "what doesn't match"?

AppleCyder (NovaSprite)OP•9mo ago

Like should they both be able to get me an output if done correctly or is there something in the console.write box that is preventing that from happening?

Angius•9mo ago

The executable code should be inside of the main method Instead, it's inside of the class That is one of the issues $structure

MODiX•9mo ago

namespace Namespace;

[Attribute]
public class Class
{
    public string PublicField;
    private bool _privateField;    

    public int PublicProperty { get; set; }

    public Class() {} // Constructor

    public void Method(int parameter)
    {
        var localVariable = parameter; 
    } 
}

namespace Namespace;

[Attribute]
public class Class
{
    public string PublicField;
    private bool _privateField;    

    public int PublicProperty { get; set; }

    public Class() {} // Constructor

    public void Method(int parameter)
    {
        var localVariable = parameter; 
    } 
}

Angius•9mo ago

Classes can contain members. Fields, properties, methods They don't actually run, they don't execute, they're just containers Only methods inside of those classes run, execute If you want code to run, it must me inside of a method

Angius•9mo ago

Angius•9mo ago

Code goes in method Between the {} braces

AppleCyder (NovaSprite)OP•9mo ago

I know it won't run but like this...

using System;
namespace PowerNumber
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.Write("Enter the base:");
            base = Convert.ToInt32(Console.ReadLine());

            Console.Write("Enter the second exponent:");
            power = Convert.ToInt32(Console.ReadLine());

            double result = Math.Pow(base, power);
            Console.WriteLine("\n\nThe sum of the two numbers is " + result);

            int PowerFunction(int base, int power)
            {

                if (power != 0) return base * PowerFunction(base, power - 1);
                else return 1;

            }

        }
        
    }

}

using System;
namespace PowerNumber
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.Write("Enter the base:");
            base = Convert.ToInt32(Console.ReadLine());

            Console.Write("Enter the second exponent:");
            power = Convert.ToInt32(Console.ReadLine());

            double result = Math.Pow(base, power);
            Console.WriteLine("\n\nThe sum of the two numbers is " + result);

            int PowerFunction(int base, int power)
            {

                if (power != 0) return base * PowerFunction(base, power - 1);
                else return 1;

            }

        }
        
    }

}

Angius•9mo ago

Yes, that's where code goes And methods/functions go into classes That's where PowerFunction should go The opposite move

AppleCyder (NovaSprite)OP•9mo ago

Ok So then I have to make it so that the integers equal to 0 right?

Angius•9mo ago

Which integers and why? If you're asking if you need to do

int foo = 0;
foo = Convert.ToInt32(...);

int foo = 0;
foo = Convert.ToInt32(...);

then no, there's no need. It can just be

int foo = Convert.ToInt32(...);

int foo = Convert.ToInt32(...);

There's no need to assign a variable if you're gonna be reassigning it immediately after

AppleCyder (NovaSprite)OP•9mo ago

I was meaning this int = base 0;

Angius•9mo ago

Here?

Angius•9mo ago

Here?

AppleCyder (NovaSprite)OP•9mo ago

Yes and for power and result too Then maybe it could work in the order I had before

Angius•9mo ago

If you want to declare a variable, yes, the type of it does need to be declared. So foo = 0; won't work, while int foo = 0; or var foo = 0; will It does not need to be assigned to immediately, though. As long as it is assigned to before you use it So

int foo;
if (something)
{
    foo = 9;
}
else
{
    foo = 172;
}
Console.WriteLine($"Number is {foo}");

int foo;
if (something)
{
    foo = 9;
}
else
{
    foo = 172;
}
Console.WriteLine($"Number is {foo}");

will work But

int foo;
if (something)
{
    foo = 9;
}
Console.WriteLine($"Number is {foo}");

int foo;
if (something)
{
    foo = 9;
}
Console.WriteLine($"Number is {foo}");

int foo;
Console.WriteLine($"Number is {foo}");
if (something)
{
    foo = 9;
}
else
{
    foo = 172;
}

int foo;
Console.WriteLine($"Number is {foo}");
if (something)
{
    foo = 9;
}
else
{
    foo = 172;
}

will not

AppleCyder (NovaSprite)OP•9mo ago

Oh ok I think that's gonna be it then But before I go I want for to ask for the base and exponent 5 times, will I need a loop for that?

Angius•9mo ago

Ideally, yes You can just write the same code 5 times, sure, but a loop will make it easier

AppleCyder (NovaSprite)OP•9mo ago

Ok got it, ty so much goodbye
