What is a pointer? A pointer is a special variable, which stores the memory address.
What are the fundamental principles of OO programming? Answer: As a developer, you might be tempted to answer that it comprises things like Encapsulation, Polymorphism, Abstraction, and Inheritance. Principles are crucial but they are not the most important aspect of what OO actually is. What is really important is to understand in what grounds OO is built upon, or in other words, what are the foundations of OO programming. The two most fundamental core concepts on which OO has been built upon in C are this pointer and Dynamic Dispatch. Obviously, there are principles like Encapsulation, Polymorphism, Abstraction, and Inheritance, but these are the consequence and not the generating force behind the OO paradigm in C.
C is a mid-level and procedural programming language. The Procedural programming language is also known as the structured programming language is a technique in which large programs are broken down into smaller modules, and each module uses structured code. This technique minimizes error and misinterpretation. More details. C is known as a mother language because most of the compilers and JVMs are written in C language. It introduces new core concepts like arrays, functions, file handling which are used in these languages. C is called a mid-level programming language because it binds the low level and high -level programming language.
There are actually two ways you can do this. Likewise, the statement "x --" means to decrement the value of x by 1. When using Call by Value, you are sending the value of a variable as parameter to a function, whereas Call by Reference sends the address of the variable. Also, under Call by Value, the value in the parameter is not affected by whatever operation that takes place, while in the case of Call by Reference, values can be affected by the process within the function. How does this aid in debugging? The idea is that if the code is in fact correct, you simply remove the comment symbols and continue on. It also saves you time and effort on having to retype the codes if you have deleted it in the first place.

What is a pointer?.
Dear readers, these C Programming Interview Questions have been designed specially to get you acquainted with the nature of questions you may encounter during your interview for the subject of C Programming. It de-refers twice to point to the data held by the designated pointer variable. By default every local variable of the function is automatic auto.
C is a computer programming language that was developed by Dennis Ritchie and released in the year The original purpose of this language was to develop a system programming language that can be used to write an operating system. This general-purpose language is structured and machine-independent, which makes its applications simple and flexible.
Despite being almost 50 years old, C is still leading the programming scene from the forefront.
C is the general and basic programming language that will create a base for other programming languages. C programming language was designed by Dennis Ritchie in Bells Lab. And it appeared around 46 years ago which is in and it was stably established on 11 December It is a crucial language of computer and it is coded in assembly language and it can run on from supercomputers to the embedded systems. The initialization of static variable Countis performed only at the first instance of the function call. In successive calls to the function, the variable count retains its previous value.
Thanks for your comments guys, good to know that you like these programming interview questions and find useful. I suggest to contribute on this with some unique programming questions you faced during interviews. Thanks Javin. I was asked: How would you implement a queue using two stacks? Agree with you Anonymous, these programming questions can be very challenging to solve in limited time if faced first time. Nice questions you can include the following Write program to Reverse a string without using array.
Я все это видел, потому что прятался в подсобке.
Ein Ring, - сказал Беккер. - Du hast einen Ring. У вас есть кольцо. - Проваливайте! - зарычал немец и начал закрывать дверь.
