Improve this question

I have a quiz that have many questions and 5 possibili开发者_如何学Goties of answers.

Lets take one question,it has follow answers:

148 - Good
5 - N/A
268 - Great
5 - Regular
11 - Bad

These are numbers collected directly from database.Now i need to show it as percentage.i.E:

Great - 45%
Good - 40

[..] and so on

Any ideas?

int na = 5;
int good = 148;
int great = 268;
int regular = 5;
int bad = 11;
int sum = na + good + great + regular + bad;

naPercent = getPercent(na,sum);

float getPercent(int value, int sum)
{
  return (value*100.0)/sum;
}

This is not a programming question, it is a math question. The percentage of each item is equal to the number of that item divided by the total number. In your example, the total number is 148+5+268+5+11 = 437. Great = 268 / 437 = 61.327%
