In C programming language, control statements are used to repeat a set of statements, while conditional statements are used for decision-making. These decision-making statements are also used to determine one or more conditions that decides whether a set of statements should be executed. They are as follows − for loop while loop do-while loop For loop and while loop, the condition specifies the number of times the loop can be executed. The "for loop" The for loop is an entry-controlled loop that executes statements until the ... Read More

Linked List Representation Linked lists use dynamic memory allocation, allowing them to grow and shrink as needed. They are defined as a collection of nodes, each containing two parts: data and a link. A linked list is a linear data structure where each element is known as a node, is connected to the next one using pointers. Unlike arrays, elements of a linked list are stored in random memory locations. The representation of data, links, and linked lists is shown below − Representation of node - Representation of Linked List -      Insertion Insertion operations in a linked list ... Read More

Stack is a linear data structure, that allows elements to be added and removed in a last-in, first-out(LIFO). The main operations are − Push Pop Display The Push Operation A stack adds a new item on top. A stack overflow occurs when the stack is full and cannot specify more items. Given below is an algorithm for Push() − Check for stack overflow. if (top = = n-1) printf("stack over flow"); Otherwise, insert an element into the stack. top ++ a[top] = item The ... Read More

Stack is a linear data structure, where data is inserted and removed only at one end.AlgorithmsGiven below is an algorithm for Push ( ) −Check for stack overflow.if (top = = n-1) printf("stack over flow");Otherwise, insert an element into the stack.top ++ a[top] = itemGiven below is an algorithm for Pop ( ) −Check for stack underflow.if (top = = -1) printf("stack under flow");Otherwise, delete an element from the stack.item = a[top] top --Given below is an algorithm for Display ( ) −if (top == -1) printf ("stack is empty");Otherwise, follow the below mentioned algorithm.for (i=0; i

Data structure is collection of data organized in a structured way. It is divided into two types as explained below −Linear data structure − Data is organized in a linear fashion. For example, arrays, structures, stacks, queues, linked lists.Nonlinear data structure − Data is organized in a hierarchical way. For example, Trees, graphs, sets, tables.QueueIt is a linear data structure, where the insertion is done at rear end and the deletion is done at the front end.The order of queue is FIFO – First In First OutOperationsInsert – Inserting an element into a queue.Delete – Deleting an element from the ...

A file is a collection of data stored in secondary memory. Files are used to store information that programs can determine. A file represents a sequence of bytes, Whether it is a text file or a binary file. It is a collection of records or is a location on the hard disk where data is stored permanently. Operations on Files The operations on files in the C programming language are as follows − Naming the file Opening the file Reading from the file Writing ... Read More

File is collection of records or is a place on hard disk, where data is stored permanently.Need of filesEntire data is lost when a program terminates.Storing in a file preserves the data even if, the program terminates.If you want to enter a large amount of data, normally it takes a lot of time to enter them all.We can easily access the content of files by using few commands.You can easily move your data from one computer to another without changes.By using C commands, we can access the files in different ways.Operations on filesThe operations on files in C programming language ...
