Resolved C# Homework

[nereloyka13]

Hi, I had homework questions I couldn't do it myself, can you help?



Question 1. a program that takes the square of all the numbers starting from 1 and ending with the entered number and prints the squares of the numbers and the sum of their squares from the screen.I was able to print their squares, but I couldn't take and print their totals.



Question2. Console.WriteLine(Result(2,5,7)); //((2+3+4+5)+ 7*7)=63 I couldn't do anything about it, can you help me.

i do it first question

namespace homework
{
    class Program
    {
        static void Main(string[] args)
        {
            int karesi;
            Console.Write("Enter a number: ");
            int sayi = int.Parse(Console.ReadLine());
            for (int i = 1; i <= sayi; i++)
            {
                karesi = i * i;
                Console.WriteLine(karesi);
            }
            int toplam = 0;
            for (int i = 1; i <= sayi; i++)
            {
                toplam += i * i;
            }
            Console.WriteLine("the sum of the numbers from 1 to the entered value:");
            Console.WriteLine(toplam);
            Console.ReadKey();
        }
    }
}

i did the first question, but I have no idea about the second question i can be glad if you give me a hint

We are not in your class, but I'm guess that is your teacher's way of asking that you write a method named Result that takes 3 integer parameters, does the operation in the comment, and returns the computed value. Is that his/her style?

yess

Ok. So how would you go about writing that method?

namespace result
{
    class Program
    {
        static int Sonuc(int a, int b, int c)

        {
            int sqr = 0;
            int total = 0;
            for (int i = a; i <= b; i++)
            {
                total += i;
            }
            if(c == null)
            {
                //???????????
            }
            sqr = c * c;
            total += sqr;
            return total;
        }
        static void Main(string[] args)
        {
            Console.Write("Sayı girin: ");
            int sayi = Convert.ToInt32(Console.ReadLine());
            Console.Write("Sayı girin: ");
            int sayi2 = Convert.ToInt32(Console.ReadLine());
            Console.Write("Sayı girin: ");
            int sayi3 = Convert.ToInt32(Console.ReadLine());
            int ttl = Sonuc(sayi, sayi2, sayi3);
            Console.WriteLine("Girdiginiz sayıların toplamı  " + ttl);
        }
    }

how can I print the sum of the numbers from the first number to the second number without squaring it when the value c is not entered here.
example: sayi =5 sayi2=7 //5+6+7=19

Congratulations!!! You did it! You didn't even need or help.

You are worrying about a non-event. int can never be null.
