```
dig_ctrl_var = vote_amt[p]+48;  ?



lcd display ascii character.

48 = 0 in ascii
```
how u will display 5 on lcd?

simple

add 5 in 48 =53

53 decimal charatcer is equal to 5 in ascii characters.

have a look on ascii table . just google it ..

the above statemnt is taking a number from a array , converting that number to ascii and copy to dig_ctr_var.
