C Program to implement the Searching Technique – Linear Search

 Linear Search (works on unsorted arrays)

Program:

#include <stdio.h>

int main() {

    int arr[100], n, i, key, found = 0;

    printf("Enter number of elements: ");

    scanf("%d", &n);

    printf("Enter %d elements:\n", n);

    for(i = 0; i < n; i++) {

        scanf("%d", &arr[i]);

    }

    printf("Enter the element to search: ");

    scanf("%d", &key);

    for(i = 0; i < n; i++) {

        if(arr[i] == key) {

            found = 1;

            printf("Element found at position %d (index %d)\n", i + 1, i);

            break;

        }

    }

    if(!found) {

        printf("Element not found in the array.\n");

    }

    return 0;

}
