3,994 PointsChallenge task Step 3 of 4: Not sure why given answer is incorrect
The question: Declare another variable named 'planck' of type NSNumber and assign it the value 6.626
My answer of:
NSNumber *planck = [NSNumber numberWithFloat:6.626];
was said to be wrong. How does that vary from:
NSNumber *planck;
planck = @6.626;

Task 3 of 4 in the code challenge is simply combining the instructions in the first two task of the code challenge.
Instead of declaring just the variable and in a second line of code assign the value, in this challenge you will do both at the same time.
Hint: You won't need to pass any messages or use any methods to complete the task. Just remember to use the NSNumber literal expression like you already did in code line 2. aka the @ symbol.
