Linear search

Program:

 #include<stdio.h>
int main()
{
int a[100],n,search,i,flag=-1;
printf("Enter no. of elements: \n");
scanf("%d",&n);
printf("Enter array elements: \n");
for(i=0;i<n;i++)
{
scanf("%d",&a[i]);
}

printf("Enter value to find\n");
        scanf("%d",&search);
  for(i=0;i<n;i++)
{
if(a[i]==search)
{
flag=i;
break;
}
}
 
if(flag>=0)
{
    printf("Successful search at position %d",flag);
}
else
{
    printf("Unsuccessful search...");
