Welcome to the Course ”?Learn C++ From Interview Questions “

This course is from a software engineer who has managed to crack interviews in around 16 software companies.

Sometimes, life gives us no time to prepare, There are emergency times where in we have to buck up our guts and start? bringing the situations under our control rather then being in the control of the situation.? At the end of the day, All leave this earth empty handed. But given a situation, we should live up or fight up in such a way that the whole action sequence should make us proud and be giving us goosebumps when we think about it right after 10 years.

We observe in quite a lot of interviews that most of us find it quite confusing (at the moment) to answer basic questions like the format of the a.out file, not having a clear understanding of the distinction between protected and private data members of the class, finding it difficult to create static libraries and dynamic libraries, not knowing that is there is really a?difference between static and dynamic libraries, confusion in the usage of different combinations of dynamic memory allocation and free calls like new, delete, malloc and free , unknown about the?difference between up casting and object slicing, thinking that the concepts of?function templates and template functions are similar.?

The basic problem is here even though most of us?are good at concepts, We?get confused while answering when we?come across a tricky question. As we all know, these tricky questions are simpler ones which are twisted and turned while asking them?in the interviews. This is just to confuse?the candidate in order to check whether the candidate really has a strong hold on the concepts.

Here in this course, We have tried an approach where in we are trying to make our audience understand the concepts of c++ through tricky interview questions.

This course is designed for almost 7.5 hours and a preview of 30 mins. Please go through the c++ questions dealt and the preview of the course. If you are interested, Kindly enroll in the course.?

Kindly adjust the talking?speed in accordance to your convenience (Please set the course narration speed to 1.24x on your conveniencce.). The concepts are presented in Neutral English.??

As per Udemy Policy, you can always refund if?you want to withdraw from the course at any point of time.

Frequently Asked Questions

How long do I have access to the course materials?

You can view and review the lecture materials indefinitely, like an on-demand channel.

Can I take my courses with me wherever I go?

Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don’t have an internet connection, some instructors also let their students download course lectures. That’s up to the instructor though, so make sure you get on their good side!
