c/c++ : electrocardiogram data acquisition

[FunZooL]

akum sume

ermmm camni... funzool nak wat program yg acquire data (ecg signal) dari rs-232(serial) thru comm port 2 n then plot graf ecg tuh. dah compile n debug, tapi still tabley nak debug sampai tade error. dah fenin dah. ada sesape bley tulun cekkan tak? stakat ni ada 5 error remaining... kat bawah funzool ada tunjuk katne error tu occur... thanx in advance. jenis compiler = turbo c 3.0

huhuhuh sedeynyer.. tade org bley tulun ke... :uwaa:

try to match the "{"..."}" carefully and you'll see the problem.

Hint: check the "}" for the "if" before the first "else" error.
