Re: any idea how to assign values to specific variables

If you use the console to input data then use

Console.ReadLine() as follow

Say that you want to enter a string

Console.WriteLine("enter your name");
string Name = Console.ReadLine();

Now if you want enter variable other than string

Console.WriteLine("Enter your age");
int Age = Convert.ToInt32(Console.ReadLine());

Re: any idea how to assign values to specific variables

Beforehand, sorry for my english...
The || - is short version of |.
I.e. if you have simple condition like this:
(a||b) then, there is no difference, what operator to use. In case with complex condition:
((a==b)||(c==d)||(e==f)) will be difference. The || operator will be checking the conditions, untill it find TRUE. If it happened on (a==b), the other conditions will not be checked. If you are choose the | operator, then all conditions will be checked necessarily.

The || - is short version of |.

That is not quite true, but I realize at first it was fuzzy for myself also.

|| is a conditional OR, it works with booleans : Abool || Bbool, if Abool is true it won't look at Bbool.

| is a bitwise OR it works with booleans and with integral types, it will always perform a bitwise OR on both sides.

Look at this code snippet I found on MSDN(search for C# operators)

C# Syntax (Toggle Plain Text)
class ConditionalOr
{
    static bool Method1()
    {
        Console.WriteLine("Method1 called");
        return true;
    }
 
    static bool Method2()
    {
        Console.WriteLine("Method2 called");
        return false;
    }
 
    static void Main()
    {
        Console.WriteLine("regular OR:");
        Console.WriteLine("result is {0}", Method1() | Method2());
        Console.WriteLine("short-circuit OR:");
        Console.WriteLine("result is {0}", Method1() || Method2());
    }
}
/*
Output:
regular OR:
Method1 called
Method2 called
result is True
short-circuit OR:
Method1 called
result is True
*/
class ConditionalOr
{
    static bool Method1()
    {
        Console.WriteLine("Method1 called");
        return true;
    }

    static bool Method2()
    {
        Console.WriteLine("Method2 called");
        return false;
    }

    static void Main()
    {
        Console.WriteLine("regular OR:");
        Console.WriteLine("result is {0}", Method1() | Method2());
        Console.WriteLine("short-circuit OR:");
        Console.WriteLine("result is {0}", Method1() || Method2());
    }
}
/*
Output:
regular OR:
Method1 called
Method2 called
result is True
short-circuit OR:
Method1 called
result is True
*/
