Thread: Selection sort

i have two logics for selection sortind...pointer p is for arrays base address.
1st logic:

Code:

void selectionSort(int *p)
{
  int i,j,temp;
  for(i=0;i<24;i++)
  {
    for(j=1;j<25;j++)
    {
      if(*(p+i)>*(p+i+j))
      {
        temp=*(p+i);
        *(p+i)=*(p+i+j);
        *(P+i+j)=temp;
      }
   }
 }
}

2nd logic:

Code:

void selectionSort(int *p)
{
  int i,j,temp;
  for(i=0;i<24;i++)
  {
    for(j=i+1;j<25;j++)
    {
      if(*(p+i)>*(p+j))
      {
        temp=*(p+i);
        *(p+i)=*(p+j);
        *(P+j)=temp;
      }
   }
 }
}

My question is---logic 1 is not working correctly...i am not able to find out any error.....if anybody?????plzzz explain the fault

i got it....thnxxx a lot!

Hard way...

Code:

void selectionSort(int *p)
{
  int i,j,temp;
  for(i=0;i<24;i++)
  {
    for(j=1;j<25;j++)
    {
      if(*(p+i)>*(p+i+j))
      {
        temp=*(p+i);
        *(p+i)=*(p+i+j);
        *(P+i+j)=temp;
      }
   }
 }
}

Easy way....

Code:

void selectionSort(int *p)
{
  int i,j,temp;
  for(i=0;i<24;i++)
  {
    for(j=1;j<25;j++)
    {
      if(p[1] > p[j]))
      {
        temp= p[i];
        p[i] = p[j]);
        p[j] =temp;
      }
   }
 }
}
