int linearsrch(int *a,int n,int key)
{
if(n==0)
{
return -1;
}
if(a[0]==key)
{
return (what should I write to return return index of the key element) ;
}
return linearsrch(a+1,n-1,key);
}

Instead of changing your pointer to iterate over the array , you should rather use a seperate index variable to iterate. This way , you can return the value of index variable when you find the key data in your array.
int linearsrch(int *a,int i,int n,int key)
{
if(i == n)
{
return -1;
}
if(a[i]==key)
{
return i;
}
return linearsrch(a,i+1,n,key);
}
