int lsearch (int[],int,int);
printf("\nEnter no of elements");
scanf("%d",&n);
printf("\nEnter %d value",n);
for(i=0;i<n;i++)
scanf("%d",&arr[i]);
printf("Enter key value");
scanf("%d",&key);
pos=lsearch (arr,n,key);
if(pos==-1)
printf("\n search no %d is not found",key);
else
printf("\n search no %d is found of index %d",key,pos);
}
int lsearch (int arr[],int n,int key)
{
int pos=-1,i;
for(i=0;i<n;i++)
{
if (arr[i]==key)
{
pos=i;
break;
}
