What is Qualifiers in C? Qualifiers in C are the keywords which are used to modify the properties of a variable.There are two types of qualifiers available in C language. They are const and volatile. What is Const? Constants are normal variables. Once the value of a constant is defined, it cannot be modified later […]
Functions in C Programming
What is a Function? A Function is a block of statements that performs a specific task of some kind. Every C program can be thought of as the Collection of these Functions. The below Example shows how we can write a simple function. In the above Example, we have made a function. After creating the […]
Arrays in C
Why do we need Arrays? Consider the problem of storing 10 integers. The naive way to store these integers would be to create 10 different integers variables and store 1 integer in each of them. This would be a viable solution but manipulating these variables would be a task in itself and we would have […]
Pointers in C and C++
What is Pointer in C? A pointer is a variable that holds the address of another variable to which it points. We know that if a variable is defined, it allocates some memory location. To know the address of that memory location, a pointer variable is used. Each data type has its own pointer variable. […]
Linked List vs Array
Linked List and Array are probably the most basic data structures, but their use can often be confusing. The use of the appropriate data structure can often result in an easier and more efficient code. Linked List vs Array is also a popular interview question in data structures. Linked List vs Array This article will […]
How to Find Length of a Linked List?
What is a Linked List? A linked list is a linear data structure used for storing collections of data Successive elements are connected by pointers The last element points to NULL Each element is a separate object and is called a Node Each node in a linked list comprises of two parts Data Reference to […]
How to Reverse a Linked List? (C and Python Implementation)
A Linked List is a simple but fascinating data structure that can be used to store linearly connected non-contiguous data. We are often encountered with interesting manipulative problems using a linked list as they require out-of-the-box thinking with the limited properties of the Singly Linked List. In this article, we will be discussing the problem […]
Control Structure and Input-Output in C
Control Structure in C defines how the statements in the program are going to execute. A statement is a single line or instruction in a program. Control Structure in C Control Structure, also known as Control Flow tells that in which order each statement is going to execute. We will discuss following types Sequential Flow […]
Programming in C
We would start writing basic programs in C now. You need to have required software installed and configured in your system. Refer to the article of Hello World and ensure that you are able to compile and run the program. Understanding the basic syntax Syntax is basically the grammar or arrangement of words in language. […]
Operators in C
Operators are essential components in programming for logical and mathematical functions. Operators in C programming are categorised in following ways. Arithmetic Operators in C Binary Arithmetic operators These are of 5 types. We are assuming a=8 and b=2. Addition: ‘ + ‘ a + b //Answer: 10 Subtraction: ‘ – ‘ a – b //Answer: […]
