C Interview Questions and Answers(2025)
In C, error handling is typically done through a combination of return codes, error messages, and sometimes, specialized error-handling functions. C does not provide built-in exceptions like higher-level languages, so error handling in C is generally done in a more manual way. Below are several common techniques for handling errors in C:

The
const
keyword in C is used to define variables whose values cannot be changed after initialization. It serves as a way to protect data from accidental modification, making the program safer and easier to understand. Here's how it works:

A
function pointer
in C is a pointer that points to a function instead of pointing to a variable. It allows you to store the address of a function and call it indirectly through the pointer. This is useful when you want to pass functions as arguments to other functions, implement callbacks, or handle dynamic function selection at runtime.

Top C Programming Interview Questions (2025)
Memory management in C is a critical aspect of programming and involves the allocation, usage, and deallocation of memory during program execution. C provides developers with a fine-grained control over memory, unlike higher-level languages that manage memory automatically (e.g., garbage collection in languages like Java or Python). Understanding how memory management works in C is essential for writing efficient and error-free programs.

A
segmentation fault
(often referred to as a
segfault
) in C occurs when a program attempts to access a memory location that it is not allowed to access. This results in a runtime error that usually causes the program to crash. Segmentation faults are typically caused by improper memory access, such as reading from or writing to invalid memory locations.
