hi guys...plz help me in making my program... DEVELOPMENT OF CD SHOP MANAGEMENT SYSTEM..(USING TURBO C++)
//gettin details n showing details... class cd { int issue,cost; public: void show details() { cout<<"date of issue:"<<issue; cout<<"cost of cd:"<<cost; } void main{ cd c; c.showdetails(2.5.2010,222); }
Hey!! how many threads did you create for the same problem? I can see a number of threads started by u for the same thing..
