division and modulus operator

I need Help,

How do you separate a number into its individual digits using
the division and modulus operator??

For Example:

if a user enters a string of number say:

Code:

---


cout << "Enter 5 numbers ";
cin >> numbers;

how do you separate each one???
say if the user enters 54345

how do you separate the five from the rest, then the four...etc..

thanks in advanced.

If that is the scenario you have, its simple. You can use a for loop to read in 5 characters, and subtract '0' from each one =).

Otherwise, you can start at 10000, and work down to 10:

Code:

---

_5 = num / 10000;
num%=10000;
_4 = num / 1000;
num%=1000;
...
_1 = num;

This works because when you divide, you are doing an integer divide, so it just throws the other numbers away. The mod, on the other hand, just throws the actual integer part away, and gives you what is left.

Z.

you could do the following with any amount of digits

Code:

---

cout << n%10;
for(;n; )cout<<((n/=10)%10);
