C Language Interview Question and Answers
C Language Interview Question and Answers: C language is a programming language that was developed in the early 1970s by Dennis Ritchie at Bell Labs. It is a general-purpose language that is widely used for developing operating systems, compilers, and other system software. C is a structured programming language that provides a wide range of features such as low-level memory access, bit manipulation, and dynamic memory allocation.
C Language Interview Question and Answers: It is also a powerful language that allows programmers to write efficient and portable code. C language is one of the most popular programming languages and has influenced the development of many other programming languages such as C++, Java, and Python, Here we are Providing Important C Language Interview Question and Answers.
C Language Interview Question and Answers;
Q: 1. What is C language?
Answer: C is a high-level, procedural, compiled programming language that was developed by Dennis Ritchie in the early 1970s at Bell Labs.
Q: 2. What is the difference between C and C++?
Answer: C is a procedural language, while C++ is an object-oriented language. C is primarily used for system programming, while C++ is used for developing applications and games.
Q: 3. What is a pointer in C?
Answer: A pointer is a variable that holds the memory address of another variable. It is used for dynamic memory allocation, passing arrays and structures to functions, and accessing hardware devices.
Q: 4. What is the difference between array and a pointer?
Answer: An array is a collection of data of the same data type that is stored in contiguous memory locations. A pointer, on the other hand, is a variable that holds the memory address of another variable.
Q: 5. What is the use of the “const” keyword in C?
Answer: The “const” keyword is used to declare a variable as read-only, meaning that its value cannot be changed once it has been initialized.
Q: 6. What is the difference between a “struct” and a “union” in C?
Answer: A “struct” is a collection of data items of different data types that are stored in a contiguous memory location, while a “union” is a data type that allows different data types to be stored in the same memory location.
Q: 7. What is a “bitwise operator” in C?
Answer: A bitwise operator is an operator that operates on individual bits of an integer.
Q: 8. What is the “ternary operator” in C?
Answer: The ternary operator is a conditional operator that takes three operands and evaluates to a value based on the result of the condition.
Q: 9. What is the difference between “malloc” and “calloc” in C?
Answer: “malloc” is used to allocate memory dynamically, while “calloc” is used to allocate memory dynamically and initialize it to zero.
Q: 10. What is the difference between “break” and “continue” in C?
Answer: The “break” statement is used to exit a loop, while the “continue” statement is used to skip the current iteration of a loop and move on to the next one
