C program to implement linear search

#include<stdio.h>

 

/* Function to implement search operation */

int findElement(int arr[], int n,int key)

{

    int i;

    for (i=0; i<n; i++)

        if (arr[i] == key)

            return i;

 

    return -1;

}

 

/* Driver program to test above function */

int main()

{

    int arr[] = {12, 34, 10, 6, 40};

    int n = sizeof(arr)/sizeof(arr[0]);

 

    //Using a last element as search element

    int key =40;

    int position = findElement(arr,n,key);

 

    if (position==-1)

        printf("Element not found");

    else

        printf("Element Found at Position: %d", position+1 );

 

    return 0;

}

Output:

Element Found at Position: 5
