returning an appropriate string for an expected int value ??

[Neildadon]

Hi can anyone help?

Im trying to write a single function which sets a small array with 2 characters to the ordinal suffix of a number. 1st, 2nd, 3rd 4th etc

and the suffix refers to the laters.

my function prototype is

void suffix(int n, char suff[]);

and i have made the following declarations

char s[5];
int x;

and with the result of the call

suffix(x,s);

will give the appropriate string in s for any given positive value of x from 0 to 9999

a possible pattern i have found is that 4 - 20 end in th

then the first three after that have st,nd,rd

is there a command that can read the last digit of an integer number ?

because if there is then i can use conditions easier and compare the last digit against the tests to see what its suffix ( letters ) are.

any help much appreciated.

how would you strip that last digit from the number using maths?

maybe like this....

last_digit = num%10;

you need a bigger array also.

9999th is 7 chars long. That cant be stored in 5
