What is Shell Sort in Data Structure with Example?

by

  What is Shell Sort in Data Structure? Shell sort is one of the oldest sorting(ascending order) algorithms named after its inventor Donald L. Shell (1959). Shell Sort is a sorting algorithm that is an improved version of Insertion Sort. It works by comparing and exchanging elements that are far apart, progressively reducing the gap between … Read more

What is Recursion in Data Structure?

by

Introduction to Recursion in C Data Structures Recursion in data structure is a process where a function calls itself to solve smaller instances of the same problem until it reaches a base case, which stops the recursion. It is a fundamental concept used in programming and data structures to solve complex problems in a simpler, … Read more

WHAT IS THE STRUCTURE OF THE C PROGRAM?

by

The structure of a C program is typically organized into several parts. Here’s an outline of the key components of a basic C program: 1.Preprocessor Directives These are instructions to the C preprocessor. They usually include library imports or macro definitions and start with #. Common examples: #include <stdio.h>  // For input/output functions #include <stdlib.h> … Read more

Pointer to Array in C
