This bubble sort is kinda freaks me out. I got it two other ways with Number of comparisons = 48 and 81 but this one ....
Data item in original order
2 6 4 8 10 12 89 68 45 37
after passing 0 : 2 4 6 8 10 12 68 45 37 89
after passing 1 : 2 4 6 8 10 12 45 37 68
after passing 2 : 2 4 6 8 10 12 37 45
after passing 3 : 2 4 6 8 10 12 37
after passing 4 : 2 4 6 8 10 12
after passing 5 : 2 4 6 8 10
after passing 6 : 2 4 6 8
after passing 7 : 2 4 6
after passing 8 : 2 4
Data items in ascending order
2 4 6 8 10 12 37 45 68 89
Number of comparisons = 24
Press any key to continue
part of my code
for (int i = SIZE-1; i >= 0; i--)
{
for (int j = 1; j <= i; j++)
{
if (a[j-1] > a[j])
{
temp = a[j-1];
a[j-1] = a[j];
a[j] = temp;
}
numberOfComp++; //// [b]this is what i want to change [b]
}
Regards.

The Code is

#include <iomanip>
using std::setw;
#include <cstdlib>
#include <ctime>
int main()
{
const int SIZE =10;

int numberOfComp=0,temp,counter=10,coun=0;
cout <<"Data item in original order\n";
for(int b=0;b<SIZE;++b)
cout <<setw(4)<<a;
cout <<"\n\n";
for (int i = SIZE-1; i >= 0; i--)
{
for (int j = 1; j <= i; j++)
{
if (a[j-1] > a[j])
{
temp = a[j-1];
a[j-1] = a[j];
a[j] = temp;
}
numberOfComp++;
}
if(coun<9)
{
cout << "after passing " << coun <<" : ";
for(int o=0;o<counter;o++)
cout << a[o]<<" ";
coun++;
counter--;
}
cout<<endl;
}
cout <<"\n\nData items in ascending order\n";
for(int j=0;j<SIZE;j++)
cout <<setw(4)<<a[j];
cout << "\nNumber of comparisons = " << numberOfComp<<endl;
return 0;
}
