Question

I am new to iPhone. I tried a lot to declare 2D array but I am unable to get the result.

NSMutableArray *outerarray = [[NSMutableArray alloc] init];
outerarray = [NSMutableArray arrayWithObjects:
    [NSMutableArray arrayWithObjects:@"10-20","21-30","31-40","41-50","51-60","61-70","71-80","81-90","91-100",nil,
    [NSMutableArray arrayWithObjects:@"10-20","21-30","31-40","41-50","51-60","61-70","71-80","81-90","91-100",nil],
    nil];

I want to combine two arrays elements and compare it with other element.

Anyone can help me please?

@"..." is an NSString. "..." is not, it’s a C string constant. You need to use the @"..." syntax for all NSString objects you’re putting into an NSArray.
