Learn C++ From Interview Questions
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 adifference 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 thedifference between up casting and object slicing, thinking that the concepts offunction templates and template functions are similar. The basic problem is here even though most of usare good at concepts, Weget confused while answering when wecome across a tricky question. As we all know, these tricky questions are simpler ones which are twisted and turned while asking themin the interviews. This is just to confusethe 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 talkingspeed 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 ifyou want to withdraw from the course at any point of time. The Questions handled in the course is as follows: Where are the function declarations foundWhere are the function definitions foundAfter compilation, are the function definitions found in a.out fileIn static library, are the library files part of the executable file (a.out)In dynamic library, are the library files part of the executable file (a.out)What is the full form of a.outWhat is the format of a.out fileIs reference a constant pointerWhat happens when a reference variable is re-assigned a value from another variableWhat happens when a reference variable is used with & and is re-assigned a value from another variableWhat is the difference between a reference and constant pointerWhat is the advantage of a reference over a pointerHow does a reference to a reference workIn the given program, convert all the const pointer statements to referencesExplain the below statements: int *const p; const int *p; const int * const p; int const *p;What is the difference between the operators (&) and (&*) when used in the context of pointersIn C++, is it mandatory to name a structure or a unionIs the life time of a locally declared reference limited to the function in which it is declaredDeclare the following: an array of 5 integers an array of 5 pointers a pointer to an array of 5 integers a reference to an array of 5 integersIs it possible to create an array of referencesCan we have multiple definitions of a function in a single moduleWhat is the difference between declaration and definition of a variableDefine a structure which contains a member function to add 2 of its data members and print the resultDoes a pointer to a variable act like a constant reference OR Does a reference to a variable act like constant pointerA reference can point to different variables but a variable cant be tied to multiple referencesDoes scope resolution operator help us in retrieving only the value of global variables whose identifier names are similar to the local variable namesWhat is the difference between the below two statements: a constant reference reference is a constant pointerCan we call a pointer ( which points to a read only string ) as a constant pointerDo we get a lvalue error in an assignment statement where a function call is placed on the left hand side of the assignment operatorAre there only 2 ways to pass variables to a function? Does passing arguments by reference really advantageousIs static variable intermodular or intramodularAre Inline functions similar to macro definitionsFunction overloading is asking the same function to perform different tasks in different contexts of the programName mangling is the concept where a name management database is used to maintain different gl
