Function to Print Income of Employees with Name in Descending Order of Income

[ilovelearning]

Hey C++ Friends,

So in my PrintData function i have printed out the employees and their new incomes displayed as required by my assignment. However the last part has been causing me a bit of a headache. I am required to SORT employee information by descending new Income before printing.

I realize this may be solved by a swap by reference or swap by pointers in rearranging essentially the rows of the data. I'm so lost as to the application of passing by reference or pointers to rearrange the data. The code should be in the print data function. If you could even help guide my thinking direction it would be much appreciated. Thanks!

So the table should be sorted to print like this:

Name Title Current Income New Income
Mickey Mouse Executive Chef 55640 57420.48
Cinderella VP of Customer Service 48776 50092.95
Donald Duck CFO 41912.00 43001.71
Goofy VP of Customer Service 32968.00 33891.19

I'd have a new function like SortData to make things easier to upgrade in the future should u want to have the option of different sorting like ascending/descending or alphabetically...

Maybe u'r not there yet but u'll probably want a structure to contain each of name/title/income/rate/etc.

Sorting everything is simple is you use the income as the index for sorting. So basically, wherever the income goes, everything else for that position does too.

//this sorts the incomes (unchecked!) in descending order
for(int i=0; i<length; i++)
{
  for(int j=0; j<(length-1); j++) 
  {
    if(income[j]<income[j+1])
    { //this is where names/titles/rates/etc should get sorted too, along with income...
      temp=income[j];
      income[j]=income[j+1];
      income[j+1]=temp;
    }
  }
}

strings can be sorted in the same way. doesn't have to be special:

string strtemp = "";
      strtemp=name[j];
      name[j]=name[j+1];
      name[j+1]=strtemp;

Cant begin to tell you how thankful i am for your help. Can you add friends in this? Hahaha. The program works beautifully :) I see now how helpful it would be to have used struct and will try it in my next program! Thankkk youu so muchh. =D
