Evaluation of array positions

[Herbert Morriss]

I am getting strang results when I use an expression to calculate the array position.

System.out.println( numbersTeens[numberIn % 10] ) ; Works Fine

but

System.out.println( numbersTens[( ( numberIn/100 ) % 10)]

always evaluates to numbersTens[0].

[fred rosenberger]

what kind of values are you getting for numberIn? if it's anything less that 100, then

numberIn / 100

WILL always be 0, and so the mod 10 will be 0.

are you using numbers > 100?

Maybe a little more code and output would help

[ I removed the code - Pauline ]

here's the output:

numberIn = 69

Sixty-Nine <---- right
Zero-Nine <---- wrong
Press any key to continue . . .

I hope the formatting comes out...




[Sorry to have to do that Herbert, it's just in case anyone working on this one would prefer not to see others' code before they figure it out themselves. -Pauline ]

Hi Herbert,

Welcome to Cattle Drive!

The two expressions are different. One is ((numberIn / 10) % 10) and the other one is ((numberIn / 100) % 10).

In the second expression, (69 / 100) will result in 0.
