C Programming Recursion | Learn the Fundamentals of Recursive Function in C

Recursion is a technique in computer science where a function calls itself to solve a problem. It is a powerful tool that can solve many problems elegantly and efficiently. In C programming, recursion is implemented using function calls and can solve various issues, such as traversing data structures, searching, and sorting. Factorial Function: A classic example of recursion is the calculation of the factorial of a number. The factorial of a number n, represented by n! is the product of all the integers from 1 to n. The mathematical definition of factorial can be represented as n! = n *...

C Programming – Scope Rules

Scope refers to a program's visibility and a lifetime of variables. In C, variables can be defined at different levels of scope, determining where the variables can be accessed and how long they remain in memory. Understanding scope rules are important for writing correct and efficient C programs. In C, a variable can be declared at three different levels of scope: Global scope: Variables declared outside of any function have global scope and are visible and accessible to all functions in the program. These variables are also known as global variables. Function scope: Variables declared within a function have function...

C Programming – Operators

In C programming, an operator is a symbol that performs an operation on one or more operands. Operators are used to manipulating variables, perform calculations, and control the flow of a program. There are several categories of operators in C, including arithmetic, relational, logical, and assignment operators. In this article, we will look at each of these categories in more detail and discuss some best practices for using operators in C programming. Arithmetic Operators Arithmetic operators perform arithmetic operations such as addition, subtraction, multiplication, and division. They are used to perform basic calculations and to manipulate numeric variables. Here is...

C++ Switch Statements | Understanding the Syntax and Usage of Switch in C++

C++ provides various control structures that enable the programmer to alter the flow of execution of a program. One such control structure is the switch statement. The switch statement is used to select one of many alternatives, based on the value of a control expression. In this article, we will discuss the syntax and usage of switch statements in C++. We will also provide examples to demonstrate how to use switch statements in different situations. What is a Switch Statement? A switch statement is a control statement in C++ that allows a program to choose between a set of alternatives...

Interview Questions About C Programming – Structures

It's important to note that the level of questions should match the level of the candidate and the position they are applying for. Can you explain a structure in C programming and its purpose? How do you declare a structure and access its members in C? Can you give an example of a real-world scenario where you would use a structure in your code? How do you initialize a structure in C? How do you pass a structure as a function argument and manipulate its data within the function? Can you explain the difference between the dot operator (.) and...

C Programming – Memory Management

In C programming, memory management is allocating and deallocating memory during the execution of a program. Memory management is an important aspect of C programming, as it determines the efficiency and stability of a program. This article will discuss the different types of memory available in C and the tools and techniques used for managing that memory.There are three types of memory available in C: stack, heap, and static. Stack memory is used for storing local variables and function call frames, and is automatically allocated and deallocated by the program. On the other hand, heap memory is used for dynamically...
