string s1 = null;
string s2 = “stuff”;

if(s1 == s2)
Console.Write(“== says they match”);
if(s1.Equals(s2))
Console.Write(“Equals says they match”);

you’ll find that the first works fine, while the second throws an exception. Granted, using an equality operator for a comparison operation, which was the context of how it was mentioned in the article, is still inappropriate, but the article seems to suggest that it can’t handle null string references at all, which is not correct at this time.

Other than that, you’ll have to loop through the string character by character, and evaluate each character. If it’s a space (ascii 32) then that’s where you’d break it up yourself.

I am in need of help, i want to take a string input from a user and then store each word separated by space in an array (NOT ALLOWED TO USE SPLIT). Any suggestions

The secret is to use positions when you write to the console.

for(int x = 1; x <= 100; x++)
{
Console.SetCursorPosition(5, 5);
Console.Write("{0}", x);
}

This would write out 1 to 100 all in the same poition within the console. SO using some pre-planning you could write all sorts of stuff out to a console window without it ever scrolling.

i want to type a string while there is a for-loop timer?

is that possible??

and how can i do that?

i’m now changing my plan to jumble the random words in my array.. how can i do that and compare if the answer is true?

string[] word = { “LION”, “APPLE”, “BAG”, “HORSE”, “RING”, “DOG” };

Random r = new Random();
int count = word.Length;

for (i = 0; i < 4; i++)
{

int index = r.Next(count);

Console.Write("nttt{0}", word[index]);
Console.Write("ntttType here: ");
input = Console.In.ReadLine();

how can i jumble the random words?
Hope someone can help me
