Study guide
In this lab you write C++ programs covering structures, unions and classes, member functions (inside and outside, inline, static, friend), objects and arrays of objects, constructors and destructors, base and derived classes with all visibility modes, single, multilevel and multiple inheritance, function and operator overloading, early and late binding, virtual and pure virtual functions and file streams. Relate each program to the OOP concept it demonstrates.
Why Software Lab-III (OOPs using C++) Matters
These practical programs are the standard exercises in practical exams and in OOP interview questions.
How to Prepare for Software Lab-III (OOPs using C++)
- Write programs from scratch and then try variations.
- Be ready to explain which concept each program shows.
- Check for file-open errors in file programs.
