kung nahan dyud ka e pointer2x butangan ra ing ani hehe, pa char2x
butangi lang na sa mga rates bai.


ikaw na sad bahala sa parking rates wa nako gi tanaw imong rates.

pwede sad ing.ani para ma-eliminate nimo ang katong '*' para sa pointers. btw, kinupya ra nako na gikan ni emailroy. Dili na nimo needed mag sige ug butang ug '*' if magtawag ka sulod sa function. then inig pass nimo dili na sad needed ang '&' nga sign.

the program design itself needs no pointers..

pointers design or more applicable for database programming..

[Maikeru]

But lets hear it from TS if it is ok not to use pointers. Because, what if that is a school exercise and they are required to use a pointer?

[poche]

sori TS..

bitaw, kng need gyud ug pointers ky mao ang exercise sa scul, i thnk da problem nimu sa imo giingun is ang value communication/assignments nimu..

try assign value manually, then check if sakto ba ang output..basin sa declaring of variables raka nsayop..

additional advice(same sa previous post): organize ur program(sa bisaya pa ibalay2x TS arun mkita nimu unsa problem dayun).

[haxors]

Mga master salamat kaayo sa inyong tabang..... Baguhan pa jud ko ini nga programming kay 1st year pako sa UC wala jud koy alamag...ining C programming once again salamat sa inyong presensya....tiguwang nako ni iskwela ug programming.....

[haxors]

ang kini nga problem mga master dipindi ra sa estudyante kung unsaon niya pag sulbad ang exercise kamo mga master kung kamo ang pa solvon unsa mga mga coding inyo gamiton.. nga ing ini ang output:

Type of Vehicle: Car or Bus or Truck

TIME-IN xxx A/P/N/M (Ang A - am, P - pm, N - Noon ug ang M - Midnight)
TIME-OUT xxx

PARKING TIME XX:XX
ROUNDED TOTAL XX:XX (kung ang minute naay value e round off na niya ngadto sa oras bali e add na siya).


TOTAL CHARGE Php XX.XX
