total_percentage=(sub1+sub2+sub3+sub4+sub5)/500;
cout<<"the total\n"<<total_percentage;
getch();
}

it is showing 0 always.

Answer 1

(int + int + …) is int.
500 is int.
int / int gives the expected result rounded off.
2/3 = 0
5/3 = 1
25/2 = 12

You must do a static_cast<double>(one_of_your_division_operands)

It converts the argument to a double precision floating point number.
