i have connected 10 7-segment displays to PIC16f877, each 2 displays are grouped together and i am using multiplexing to output data to them . how to split a 2 digit number like 12 to "1" and "2" using CCS to display each on a 7-segment display?

regards
 

the matter is easy as I think. To split a number into its ones and tens, divide the number by 10 to get the tens and the remainder is the ones.
the code may written in C like:
unsigned char x,ones,tens;
x=12;
tens=x/10;
ones=x%10;
