NSString* message;
Int Random_number1;

random_number1= 1+arc4random()%100;
message= [NSString stringWithFormat: @"%d", random_number1] ;

1. variable names are case sensitive
2. its "int" or "NSInteger", not Int

	NSString* message;
	NSInteger random_number1; // resp. "int random_number1;"
	random_number1= 1+arc4random()%100;
	message= [NSString stringWithFormat: @"%d", random_number1] ;

I think it is not the case,
i have try to change int -> NSInteger
it get the same problem

[finefin]

did you change "Random_number1" to "random_number1"?
That's what I meant with "case sensitive".
I tested the snippet i posted and it works like a charm.

What is the error message that you get?

[finefin]

let me guess. it's

'random_number1' undeclared (first use in this function)
Unused variable ‘Random_number1'

is it?

[fming]

Sorry no
I think it related to "message" is a pointer
But I pass a value into it directly
If I change the code to:
Message =@"helloworld";
It working well
I do not know how to pass a valuable .
Like:
Message=@random_number1;

Thanks

Post the exact code you are trying. No retyping; copy and paste.

And post the exact error message you are receiving.

I will not ask again.
