Let’s write the following method
public void printDigits( int n){
}
Walk through of how the code should work:
the algorithm inolves
1) extract last digit
2) print last digit
3) remove last digit
keep doing this until there are no more digits
Example :
Let’s look at printDigits( 345)
Walk through of how the code should work:
the algorithm inolves
1) extract last digit ‘5’
2) print last digit print ‘5’
3) remove last digit now n should be ’34’
do this for ‘4’ and then ‘3’ until there are no more digits
You need a while loop. Think about it. What is the value of n when there are no more digits?
