GUI Embarcadero C++
Hej.
Är det någon här inne som skulle kunna hjälpa mig?
Jag gör en miniräknare i embarcadero C++ men lyckas inte få subtraktion, multiplikation och division att funka.
Har lyckats att få så att knapparna visar så det ska vara men när man gör uträkningen blir allt i addition.
Funderar på om det är en if-sats man ska använda, men vet inte hur den ska va utformad eller vart den ska va. Efter ett evigt googlande söker jag mig nu hit och hoppas att någon kan hjälpa mig. Klistrar in koden jag har här under.
