如何排序指针数组所指向的数组？

Question

I need to sort arrays that pointed by pointers array with this function (i need only with pointers, without these [ ])

void getSort(int** p2a, int arrSizes[]) //p2a is a array of pointers to diffrent arrays

I tried bubble sort:

if (i < 5)
{
    for (j = 1; j < arrSizes[i]; j++) // I started with 1 bcz i dont want to sort the first value
    {
        for (k = j + 1; k < arrSizes[i]; k++)
        {
            if (*(*(p2a + i) + j) > *(*(p2a + i) + k))
            {
                temp = *(*(p2a + i) + j);
                *(*(p2a + i) + j) = *(*(p2a + i) + k);
                *(*(p2a + i) + k) = temp;
            }
        }
        i++;
    }
}

but it not sorting well... exampels:

• Before: 3 9 3 7
• After: 3 3 9 7
• Before: 3 6 1 7
• After: 3 1 6 7
• Before: 4 9 7 1 7
• After: 4 9 7 1 7

Answer 1

change the if with for solved the problem

for (i = 0; i < NUM; i++)
{
    for (j = 1; j < arrSizes[i]; j++)
    {
        for (k = j + 1; k < arrSizes[i]; k++)
        {
            if (*(*(p2a + i) + j) > *(*(p2a + i) + k))
            {
                temp = *(*(p2a + i) + j);
                *(*(p2a + i) + j) = *(*(p2a + i) + k);
                *(*(p2a + i) + k) = temp;
            }
        }
    }
}
