Sorting Arrays
Dec 7th, 2008, 12:16am  
hey there, i will really apreaciate help on this! ill be grateful for life!  

i need to bubble sort a file of numbers in ascending and descending order however for some reason the code is always geving me error or doesn't print on the screen. here's the code...

for (i = 0; i < Size-1; i++);
 for (j = Size-1; j>i; j--);
   if (nums[j-1] > nums[j]);
temp = nums[j-1];
nums[j-1] = nums[j];
nums[j] = temp;

for (i = 0; i<Size; i++){println(" "+ i)  ;  

 nums[i] = int(Strs[i]);
 OutPutLiness += " " + nums[i];
   OutPutLiness += " ";
 }
   text(OutPutLiness,90, 200);

Can point me in the right direction? PLEASE!!!

A bunch of problems:

for loops and if statement shouldn't have semicolons before them.  none of your variables are declared anywhere.  your if statement needs {brackets} to include multiple lines.

i was going to post working code but i feel like that would be doing your homework for you. this is homework right? someone else posted an identical question.

If it was a homework, i guess you missed the due date. :)

PFont f;
f = createFont("verdana", 10);
textFont(f);

background(255);
fill(0);

int nums[] = {34, 52, 6541, 415, 154, 514, 534, 514, 151, 34};
String OutPutLiness = "";

size (600,400);

for (int i = 0; i < nums.length-1; i++){
 for (int j = nums.length-1; j > i; j--){
   if (nums[j-1] > nums[j]){
     int temp = nums[j-1];  
     nums[j-1] = nums[j];  
     nums[j] = temp;
   }
 }
}

for (int i = 0; i < nums.length; i++){
 println(" "+ i);
 // nums[i] = int(Strs[i]);  // does not make sense for me.
 OutPutLiness += " " + nums[i];  
 OutPutLiness += " ";  
}  
text(OutPutLiness,5,30);
