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.
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. So, C is one of the basic and essential computing languages that developers need to know.
A void pointer is a pointer that can be used to point to any data of any arbitrary type. A void pointer can be dereferenced only after explicit casting. For example:.
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.
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.
Simply put, commands that you use in C programming are actually functions that are defined from within each header files. Each header file.
