Question and code which ı wrote below.I wrote this code by using flow chart.Everything seems true but when ı compile tis code its answer wrong.Please help me.

Question: With 8 elements
a[]={1,2,3,4,5,6,7,8}
b[]={1,3,5,7,9,11,13,15} sets are given.Write a C++ code to find the sum of the numbers of intersection sets.

#include<iostream>
#include<string.h>
using namespace std;
int main()
{

int a[]={1,2,3,4,5,6,7,8};
int b[]={1,3,5,7,9,11,13,15};
int i;
int sum=0;
for(i=0;i<=7;i++)
{for(i=0;i<=7;i++){if(a[i]==b[i]){sum=sum+a[i];}}}
cout<<"Ortak Eleman Toplami : "<<sum<<endl;
return 0;
}
This code only adds if a[i] = b[i].

When is that true?

i = 0:
a[i] = 1
b[i] = 1

i = 1:
a[i] = 2
b[i] = 3
a[i] != b[i], DO NOT ADD VALUE

i = 2:
a[i] = 3
b[i] = 5
a[i] != b[i], DO NOT ADD VALUE

i = 3:
a[i] = 4
b[i] = 7
a[i] != b[i], DO NOT ADD VALUE

i = 4:
a[i] = 5
b[i] = 9
a[i] != b[i], DO NOT ADD VALUE

i = 5:
a[i] = 6
b[i] = 11
a[i] != b[i], DO NOT ADD VALUE

i = 6:
a[i] = 7
b[i] = 13
a[i] != b[i], DO NOT ADD VALUE

i = 7:
a[i] = 4
b[i] = 15
a[i] != b[i], DO NOT ADD VALUE

ONLY when i=1.

Your code is just doing entirely the wrong thing.
