How to use "switch" to perform large numbers cases?

How to use switch to make following output?( Issit required me to defined each cases from 0,1,2,3...39=BAD ...... 100 )

Score Comment
0~39 BAD
40~69 Poor
70~89 Good
90~100 Excellent!!

It would probably be better here to use nested If/else statements.

Code:

---

if (blah >= 90)
  {do this};
  else if (blah >= 70)
      {do this};
      else if (blah >= 40)
        {do this};
        else
            {do this};

Yup nested if-else is better but i desire to know the "switch" way

Yes. A four part if/else if/else statement is just a smidge better than a 100 case switch/case statement or something weird. You can also sneak around with tables, if you really wanted to.

Code:

---

char *getScore(double score)
{
    double  scores[] = {39.0, 69.0, 89.0, 100.0};
    char  *scorestrings[] = {"BAD", "Poor", "Good", "Excellent!!"};
    int    i;

    for (i = 0; i < 4; i++)
    {
        if (score <= scores[i])
            return scorestrings[i];
    }

    return "Invalid score";
}
