int main(){
clrscr();
int val[]={1,3,5,7,9,11,13,15,17,19};
int s1=0,s2=0;
s1=sum(val,10);
s2=sum(val+4,6); // note I gave val+4
cout<<s1<<" "<<s2;
getch();
return 0;
}

The output I get:
0 - 1
1 - 3
2 - 5
3 - 7
4 - 9
5 - 11
6 - 13
7 - 15
8 - 17
9 - 19 //ok till here
0 - 9 // why is every term added with 8 instead of 4
1 - 11
2 - 13
3 - 15
4 - 17
5 - 19
6 - 21
7 - 23
8 - 25
9 - 29
100 84

I gave as val+4 but instead I see it gets added up with 8
if I give as val+2 it gets added up with 4
val+x ----> each gets added up with 2x <--- o.O

why is that?
last point --> the above prgm was written in C++
