Hello I am writing a fuction to return a number's digit in a spcific plance.

Number : 12345

here is what I have:

int get_digit(info& structure,int digit)
{
int ret_dig;

ret_dig = structure.d_pop;

Please help

Use % and / on a temproary copy of the variable.

How Would I do this....could you please give me an example?

[Daved]

12345 % 10 = 5.
(12345 / 10) % 10 = 4.
(12345 / 10 / 10) % 10 = 3.
... etc.

% means mod, or remainder (12345 / 10 is 1234 remainder 5, so 12345 % 10 = 5).

Or convert it to a string and then just use normal array-like indexing [] and some math to get the proper digit.

I think you can write a recursive function for this purpose..
