Write a C Program for Linear search in an array

This Program will Takes 3 inputs

1. For the size of array
2. Input for arrays
3. Element to be searched in array

If element is available it will return index else -1.

#include <stdio.h>
#define MAX 50
int LinearSearch(int arr[],int n,int item);
int main(void)
{
	int i,n,item,arr[MAX],index;
	printf("Enter the number of elements : ");
	scanf("%d",&n);
	printf("Enter the elements : \n");
	for(i=0; i<n; i++)
		scanf("%d", &arr[i]);
	printf("Enter the item to be searched : ");
	scanf("%d", &item);
	index=LinearSearch(arr,n,item);
	if(index==-1)
		printf("%d not found in array\n",item);
	else
		printf("%d found at position %d\n",item,index);
	return 0;
}

int LinearSearch(int arr[],int n,int item)
{
	int i=0;
	while(i<n && item!=arr[i])
		i++;
	if(i<n) 
		return i;
	else
		return -1;
}

Output

Enter the number of elements : 7
Enter the elements : 
12 13 14 15 16 17 18
Enter the item to be searched : 13
13 found at position 1
