Thread: data structure

the problem is:
write the sequential search method that find the last occurance of an item
the code runs but it donot give the right answer
here is my code

Code:

#include<iostream>
using namespace std;
  int seqsearch(int seq[],int size,int key)
{
int i;

for(i=size;i>0;i--)
{ 
if(seq[i]==key)
return i; 

return -1;
}
  }

  int main()

  {
	  int i;
	  
	  
	   int key;
	   int seq[10]={0,1,2,3,4,5,6,7,8,9};
	   
int x=seqsearch(seq,10,key);
	cout<<"enter the key"<<endl;
	cin>>key;

	cout<<x<<endl;
	 
 
  return 0;
  }
