Aslam-O-Alikum. 

MCQ's mostly conceptual thy but easy thy. jaisa k Insertion or Extraction k sign pochy, or constant or static variable or this pointer en sy related mcq's thy. Khuch past papers sy b aaye thy.

Q1:-

ik code diya how tha c1-c2-c3, or pocha tha k compiler es structure ko samjh k khud esy appropriate form main ly aaye ga? 2 Marks.

Q2:-

ik question tha, can constant object access the none constant member function of each class? 2 Marks

Q3:-

Assignment overloading operator k program likhna tha. 3 Marks

 

Q4:-

Object Oriented model bnana tha, or simple, composition, aggregation relationship b show krwany thy .  A university have 45 lectures of subjects and their 6 Assignment, 1 Quiz, MDB, GDB. 5 Marks

 

Q5:-

Pre-Decrement or Post-Decrement k overloading program likhny thy. 5 Marks

waisy overall paper esy tha mcq's b .
