In array operations, the difference between two arrays A and B is a new array containing all elements that are in A but not in B. This operation is widely used in data analysis, filtering datasets, and solving algorithmic problems. Learning to compute array differences helps programmers manage data efficiently and manipulate collections of values. […]

The intersection of two arrays is a new array that contains all elements present in both arrays. This operation is a fundamental concept in programming, used in data processing, set operations, and algorithm problems. Understanding how to find the intersection helps in comparing datasets and extracting common elements efficiently. In this tutorial, we will explore

Finding the union of two arrays is a common task in programming. The union of arrays contains all elements from both arrays but without duplicates. This concept is widely used in data processing, set operations, and algorithm problems. In this tutorial, we will explore multiple ways to find the union of two arrays in C,

Counting the number of words in a string is a common task in text processing and programming exercises. It helps beginners practice string handling, loops, and conditional logic in C. By learning this program, you will understand how to iterate through characters, identify word boundaries, and handle different spacing scenarios. This tutorial provides a complete

Counting vowels and consonants in a string is a fundamental problem in C programming. It helps beginners understand string handling, character classification, and loop logic. By learning this program, you can also apply similar logic to analyze text, validate input, or create basic text-processing programs. In this tutorial, we will write a complete C program

In programming, arrays are widely used to store multiple values of the same type. However, sometimes arrays may contain duplicate elements, which can cause problems in calculations, data analysis, or other operations. Removing duplicates from an array ensures that every element appears only once, which is often necessary in tasks such as searching, sorting, and

Checking whether an array is sorted is a fundamental problem in programming. Knowing if the elements in an array are in ascending or descending order is important in algorithms like binary search, sorting, and data validation. This task helps you practice working with arrays, loops, and conditional statements in C. In this tutorial, we will

Counting the occurrence of a specific element in an array is a common task in C programming. This operation helps you understand how data is stored, accessed, and processed in arrays. By learning to count elements, you gain insights into loops, conditional statements, and efficient ways to traverse arrays. In this tutorial, we will write

Rotating an array is a common problem in programming, and learning how to rotate an array in C helps you understand arrays, loops, memory manipulation, and algorithm optimization. In this article, we focus on rotating an array to the right by a given number of positions, often denoted as N. By the end of this

Rotating an array is a common task in C programming that helps you understand array manipulation and how data can be rearranged efficiently. In this tutorial, we will explore multiple ways to rotate an array to the left by N positions. You will see both simple methods for beginners and optimized approaches that use algorithms
