switch cases and numeric operators issue

Code:

---

#include <iostream>
#include <iomanip>

using namespace std;

int main()
{
    const int currentYear = 2010;
    string name;
    int yearBorn;
    int age;
    cout<<"Enter your name: ";
    cin>>name;
    cout<<"Oh, what a nice name, "<<name<<"."<<endl;
    cout<<"When were you born? ";
    cin>>yearBorn;
    age = currentYear - yearBorn;
    cout<<"Oh, so you're "<<age<<" years old?"<<endl;
    cin.get();cin.get();

    string msg;
    switch(age)
    {
        case (10):
            msg = "Oh, you're just a little kid,,, How cute!";
        break;
    }

    cout<<msg<<endl;

}

Program works fine, but i'd like the switch's case to work with numeric operators.
In the example I made so the case would only store that message if the entered age was 10, but i'd like to work as "< 10", so that message would be printed if the user's age was lower than 10. How could i make this switch case work with numeric operators?

You could use the dangerous bleeding-case setup:

Code:

---

switch (value) {
  case 1:
  case 2:
  case 3:
  ..
  case 9:
    //code for < 10
    break;
}

I mostly see this looked down upon, but for what you're doing you might just want to stick with if/else, especially if that's the only case you're working with...

I think that, if that really is what you want, you should use if-else cases. It will simply be more understandable and efficient.

Edit: Sorry, my answer is late :)

no, thats not the only case i'm working with, ive only made one because i couldnt figure out how to do the switch case work with numeric operator

Right, and you really can't do it in a 'decent' or 'wise' way by simply falling through all possible cases. What if you have to check for something that is >100 and <300 ?

Sometimes if-else cases are just better.

Code:

---

jus try using a temproary variable for the age that s less than 10 an the switch tat variable.
like
 if(age<=10)
  j=0;
switch(j)
{
case 0:
 msg = "Oh, you're just a little kid,,, How cute!";
        break;
    }

    cout<<msg<<endl;

}

mithr56, the suggestion you offered can cause problems if the value of 0 (or any other value you choose) could have a separate meaning aside from assigning it like you do (such as 0 oftentimes being implicitly interpreted as false). switch statements are best used when working with a distinct set of possible values. if you are looking for ranges, your code and its future readers will benefit greatly if you stick with if/else.
