Problem s prevodem typu(?) + tridama – C / C++ – Fórum – Programujte.com

Ahoj, podle Mistrovstvi v c++ delam ukol 10te lekce a pise mi to chybu (ja se v nich nevyznam vubec).. radsi ukazu konkretni kody..

chyba:

Nazdar chybu mate, tak ako vám aj oznamuje kompilátor v konštruktore triedy account
account(const char* name[SLEN]='\0', const char* acc_num[SLEN]='\0', float remainder=0.0);, ktorý má vypadať nasledovne:

account(const char * name = "", const char * acc_num = "", float remainder = 0.0f);

account(const char name[] = "", const char acc_num[] = "", float remainder = 0.0f);
