Thread: bubble sort array in acending and descending order

Code:

#include<iostream>
using namespace std;
int main(void)
{//declaration of variables
int i;
int num[10];
int temp;


for (i=0; i<=9; i++)
{
    cout<<"please enter a number\n";
    cin>>num[i];
}

cout<<"you entered \t";
for (i=0; i<=9; i++)
{
    cout<<num[i]<<"\t";
}
cout<<endl;
/*
if (i<=-100 || i<=100)
{
      cout<<" Please insert correct number"<<endl;  
      cin>>i;
}*/

for(int i=0; i<10; i++) //sort numbers in ascending order
{
  for(int y=0; y<9; y++)
  {
   if (num[y]<num[y+1])  
   {
    temp=num[y+1];  //swapping
    num[y+1]=num[y];
    num[y]=temp;
   } 
  } 
}  

cout<<"sorted number in ascending order are\t";
for (int i=0; i<10; i++)
{ 
    cout<<num[i]<<"\t";
}
cout<<endl;

// sort numbers in 
for(int i=0; i<10; i++)
{
  for(int y=0; y>i; y++)
  {
   if (num[y]>num[y+1])  
   {
    temp=num[y+1];  //swapping
    num[y+1]=num[y];
    num[y]=temp;
   } 
  } 
}  

cout<<"sorted number in descending order are\t";
for (int i=0; i<10; i++)
{ 
    cout<<num[i]<<"\t";
}
cout<<endl;
system("PAUSE");
 return 0;
}



above is my half working program, i just couldn't figure out a way to get a ascending sort to work. Can someone give me a hand? thanks

Answer available at this link: Bubble Sort

Look at the middle part of the code where it begins with... while(!sorted) {

Sorts in ascending order.

thanks i think i figured it out
