input:

123456789

output:

enter a 7-9 digit number
temp= 123456
last3= 789
first= 78
second= 9
third= 7
fourth= 8
first3= 123
middle3= 456
first1= 45
second1= 6
third1= 4
fourth1= 5
the number with a comma is
123,4564,7897

It is just a matter of keeping track of your variables.

Answer 4

@eSpeX
So what would i type in the last cout statement to get it write

Answer 5

cout<<first3<< ","<<middle3<<","<< last3<< endl;
I added this line to your code and below is the output with your code and the new code as the last two lines.

input:

1234567

output:

enter a 7-9 digit number
temp= 1234
last3= 567
first= 56
second= 7
third= 5
fourth= 6
first3= 1
middle3= 234
first1= 23
second1= 4
third1= 2
fourth1= 3
the number with a comma is
1,2342,5675
1,234,567

A pretty printed number is a string. it's easier to do the fomatting with the string than th number.
