If you are prepared for a job after studying the C programming language, you should learn about the top interview questions. related to C language so that you can successfully give your interview. Through this article, we are presenting some special interview questions with answers, which you can read and prepare for the job.
1. Why is C language called a mid-level programming language?
C language is a language in which both low-level language or assembly language and high-level language are used, which is why C language is given the status of medium-level language. Using C language, the user can write operating systems and programs.
2. What is a token?
When you use a program, there are mainly 6 types of tokens in the C language program.
- Operators
- Special characters
- strings
- identifier
- keywords
- constant
3. What are the main features of the C language?
- C language is used a lot for programming, this language has some of its characteristics,
- This language is known as an independent language or machine independent.
- C language is a type of structured programming language.
- Function-rich libraries can be made available in this language
- It is known as a mid-level programming language.
- dynamic memory management
- C language is extensible.
- It is a super fast programming language.
- The C language allows us to use pointers.
4. Why are printf() and scanf() functions used?
print () is used to print the output display.
Formatted data can be read from the keyboard using scanf().
5. What is the built-in function in C language?
The most commonly used built-in functions in C are printf(), strcpy, scanf(), strcmp, strlen, strlen, strcat, and many others.
Built-in functions in C language are also used as library functions, their use makes the work of the developer easier, some of the functions already defined in this library are predetermined, which allows programming to do. For example, if you need to print the output of your program or your program in the terminal, you can use printf().
6. What is the value of the expression 5[“abxdef”] in C language?
The type “abxdef” refers to a type string array, and the expression shown here is equivalent to “abxdef” [5]. Thus we can understand that the inner expression is equal because a[b] is equal to *(a + b), which is equal to *(b + a), and which is equal to b[a].
7. What is a Preprocessor?
It is a type of software program, which processes any source file thoroughly before sending it for compilation so that there is no problem in programming. Its main job with the preprocessor is to include header files, macro expansion, line control, and conditional compilation.
8. What is recursion in C?
During programming in C, when the function calls a copy of itself, the process is known as recursion. We can also understand it as when a function calls itself, it is called the process of recursion in C language.
9. What is a pointer in C language?
It is a type of variable by which the address of another variable is represented, or stored. From this, we can understand that the value of a variable is included in any other normal variable.
10. Why is function overloading not supported by C?
When we introduce function overloading in the source, we should also provide name mangling to avoid the name conflict of the function. It avoids overloading since you can’t strictly type in this language.
Conclusion
We hope that these C programming language interview questions will be useful to you. If you want to learn more about C programming you can always go to YouTube and watch tutorial videos. On YouTube, there are thousands of videos on C programming. For YouTube hand-holding training, use Career Ninja’s LearnTube. Learn Tube creates a course framework from the results of your YouTube search. If you search for a “C programming tutorial” on YouTube, LearnTube will show you a series of videos that look like an online course. As a beginner, you’ll go through the videos from beginning to end, as if you were taking a YouTube course customized particularly for you.
