May 23, 2024 · In this post, we will look into search operation in an Array, i.e., how to search an element in an Array, such as: Searching in an Unsorted Array using Linear Search

Sorting data There are three approaches to sorting arrays: selection sort, insertion sort, and bubble sort. As you will notice, whereas searching involves a single for loop and visiting each array location, sorting involves nested for loops, and n-1 passes through the array.

Mar 20, 2025 · Write a C program to find the position of a target value within a sorted array using binary search. Binary Search : In computer science, a binary search or half-interval search algorithm finds the position of a target value within a sorted array.

Mar 10, 2024 · Comparison sorts, like Bubble, Selection, and Insertion Sort, function by comparing elements and deciding their order based on their values. Non-comparison sorts, such as Counting and Radix Sort, do not compare elements directly but use their characteristics to sort.

Sorting and Searching (in C) ¶ Sorting is an important and well-studied topic in computer science. A sorting algorithm re-arranges the elements of an array (or string, or any similar linear data structure) from smallest to biggest. For simplicity, in these notes we’ll stick to sorting arrays of ints. For example, these numbers are in sorted ...

Here is a collection of C programs on searching algorithms, sorting algorithms, linear search, and binary search algorithms. Sorting algorithms such as selection sort, bubble sort, insertion sort, merge sort, quick sort and heap sort.

char ch; clrscr ( ); flg=0; printf ("Enter the size of the array \n"); scanf ("%d",&n); printf ("Enter the elements of the array \n"); for (i=1; i<=n;i++) { scanf ("%d", &a [i]); } do { printf ("\nEnter the number which you want to search :"); scanf ("%d", &m); printf ("\nPress 'l' for linear search and 'b' for binary search :"); ch=getch ...

Feb 22, 2025 · The function linearSearch () takes an array, its size, and a target value to search for. It iterates through the array and compares each element with the target. If a match is found, the function returns the index of the element. If the element is not found, it returns -1.

May 31, 2015 · int searchi (int n, int *array) { int c, first, last, middle, search; printf ("Enter value to find\n"); scanf ("%d", &search); first = 0; last = n - 1; middle = (first + last) / 2; while (first <= last) { if (array[middle] < search) first = middle + 1; else if (array[middle] == search) { printf ("%d found at location %d.\n", search, middle + 1 ...

Apr 14, 2025 · There exist different sorting algorithms for different different types of inputs, for example a binary array, a character array, an array with a large range of values or an array with many duplicates or a small vs large array. The algorithms may also differ according to …
