Reset b to zero in your loop ?

cout << setw(15) <<b <<endl;
b=0;

@titepanatiks
1. I don't see a multiplication arithmic operator anywhere.
2. You should declare your array and regular double variable on different lines as this is a good habit.
3. Your mistake is probably not using the variables, arrays you declared right, a math error, and/or a semantic error (logic error).
