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.
C Programming Questions and Answers
Therefore, when a variable is declared, the program knows the data type of that variable. In case of function declaration, the program knows what are the arguments to that functions, their data types, the order of arguments and the return type of the function. Therefore, we can think of definition as a super set of declaration. What are different storage class specifiers in C? Ans: auto, register, static, extern.
C programming Interview questions and answers
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.

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? A pointer is a special variable, which stores the memory address. Ampersand in front of a variable gets its address and asterisk in front of a pointer gets its value. What is null pointer? Null pointer is a pointer which cannot point to anywhere in the program, but uninitialised pointer can point to anywhere in the users program. In C, if the pointer tried to access 0th location, operating system kills the running program because operating system does not allow to access 0 th value. Define function pointer?
C Interview Questions
C is a procedural programming language. It was initially developed by Dennis Ritchie as a system programming language to write operating system. The main features of C language include low-level access to memory, simple set of keywords, and clean style, these features make C language suitable for system programming like operating system or compiler development.

Despite being almost 50 years old, C is still leading the programming scene from the forefront. The programming language has a wide variety of applications and is also the inspiration for a variety of modern, powerful programming languages, such as Java , C , and Python. Although there are very few job profiles these days that only require a high-level proficiency in C, most programming jobs necessitate a good understanding of the C programming language's fundamental concepts. So, many programming job interviews involve C Interview questions and answers.
