Structures in C Language Data types are of two types primitive and non-primitive. Primitive data types are basic one and non-primitive data types are user defined data types. For example arrays, which are the data structures whose individual data elements are all of the same type. But data structure whose individual data elements differ in […]
String Handling in C A string in C Language can be defined as a character array terminated with a special character ‘\0’ to mark the end of the string. Unlike some other high-level languages like BASIC language, C does not have built-in “string” type data. So, C has no built-in facilities for manipulating entire arrays(such

Pointer in C Language Let us understand what are the pointers in C, the Pointer operator (*) is used heavily in C Language and also called “value at address“ operator, it is used to fetch the value stored at a particular address. The pointer operator is also known as indirection operator, and has just the

Functions A function is a self contained block of code that does some specific task. A function definition has a header and body. Header A header of a function is made up of Return type: It is the data type of the value being returned by the function. If a function has no value
Arrays in C Language An array is an order sequence of finite data items of the same type that share a common name. The common name is the array name. Each individual data item in the in the list is known as element of the array. The name of an array is actually the memory
Control Structures in C The structures of a program which affects the order of execution of the statements are called control structures. The normal execution of statements is in sequential fashion but to change the sequential flow, various control structures are used. Broadly, control structures are of three types- Selection /conditional – executes as per

Input/Output Functions in C C Language doesn’t have built in input output functions to carry out input output operations. Instead, it is implemented via standard library functions called header files. What is a header file Header file contains the declarations and prototypes of the basic input/output functions used in the program files called

Operators and Expressions in C What is an Operator? An Operator is a function which works on one or more operands to produce a new value, e.g. +,-,* ,/ are some operators. Operators in C differs at some points from mathematics. So C has its own system to manipulate operators. What is operands? operand

Storage Classes in C Storage Class Specifiers 1) Scope Scope of a variable is that portion of the program in which that identifier can be used. There are two types of scopes – Block Scope When a variable is declared inside a block then it is called block scope. It’s scope from the point of

Variables in C Variable in C is a named place in memory to store a value that can be modified by the program. Variables in C can be of three types- 1) Synchronous Variables 2) Asynchronous Variables 3) Read Only Variables 1) Synchronous Variables The value of these variables can be changed only through the
