  1. XII CBSE Previous Year Question Paper QUESTION NO 2 (c) 4 Marks

  2. (c) Define a class named ADMISSION in C++ with the following descriptions : Delhi 2006 4 Private members : AD_NO integer (Ranges 10 - 2000) NAME Array of characters(String) CLASS Character FEES Float Public Members : • Function Read_Data( ) to read an object of ADMISSION type • Function Display( ) to display the details of an object • Function Draw-Nos( ) to choose 2 students randomly. And display the details. Use random function to generate admission nos. to match with AD_NO.

  3. (c) class ADMISSION { int AD_NO; char NAME[20]; //or any constant size char CLASS; float FEES; public: void Read_Data() { do { cin>>AD_NO; }while (AD_NO<10 || AD_NO>2000);

  4. gets(NAME); cin>>CLASS; cin>>FEES; } void Display() { cout<<AD_NO; cout<<NAME; cout<<CLASS; cout<<FEES; }

  5. void Draw_Nos(); }; (1 mark for proper syntax of class definition with correct class name and a semicolon to end the class definition) (1 mark for proper declaration of private members) (1 mark for proper definition of Read_Data()) (1 mark for proper definition of Display()) Note: No marks should be deducted for Not checking the range for AD_NO Not declaring or defining Draw_Nos(). (Mentioned as Draw- Nos() in the question paper)
