Sorting String Help

[Bee-Ant]

You have to sort some string data which consist of 3 elements depend on their name...for example

Code: Select all

=> How many your data ? 3

=> 1. Name : G
         Class : 3
         Color : Red
=> 2. Name : Y
         Class : 2
         Color : Blue
=> 3. Name : D
         Class : 2
         Color : White

=> Output
=> 1. Name : D
         Class : 2
         Color : White
=> 2. Name : G
         Class : 3
         Color : Red
=> 3. Name : Y
         Class : 2
         Color : Blue


I know how to sort SINGLE string...but at this, I'm still confused
Thanks for your help

You would typically have to compare each element in some order. I would recommend making a function for this.

So, if the struct is called Object and the comparison order is Name, Class, Color, you would compare it like this:

Code: Select all

int objectCompare(Object *o1, Object *o2)
{
  int result = strcmp(o1->name, o2->name);
  if (result == 0)
  {
    result = strcmp(o1->color, o2->color);
    if (result == 0)
    {
      result = strcmp(o1->class, o2->class);
    }
  }
  return result;
}

I really don't like to see someone with a question go unanswered. I hope you either figured it out in the past two weeks, or it helped.

Oops, sorry if I had offended you..no purpose on that...Errr ehm, OK...I'll save your code for my next homework...
Thanks
