hey guys I am in method and i didn't interstade why we write static when our method has no return but when we our method have a

Question

int Sqr(int x)

{

int result = x*x;
return result;
}

static void SayHi()

{

Console.WriteLine("Hello");
}

Answer 1

The static keyword is used to invoke the sayHi (); method in your main method without having to generate an instance (object) of your class Program.

namespace SoloLearn
{
class Program
{
static void sayHi() // with static keyword
{
Console.WriteLine("Hello");
}
static void Main(string[] args) // main method
{
sayHi(); // method call
}
}
}

If that word is not used, as you can see, your method sayHi(); is in the Program class, so you should create an instance (object) of that class to be able to use it.

namespace SoloLearn
{
class Program
{
void sayHi() // without static keyword
{
Console.WriteLine("Hello");
}
static void Main(string[] args)
{
Program anObject = new Program(); // New object of Program class
anObject.sayHi(); // call method from your object
}
}
}

You will understand it better when you get to class lessons.

Answer 2

Use of the `static` keyword has no relation to return statements.
