malloc动态申请失败

Question

#include <stdio.h>
#include <malloc.h>
void swap(int* x, int* y)
{
    int t;
    t = *x;
    *x = *y;
    *y = t;
}
void rank(int* nums, int size)
{
    for (int i = 0; i < size; i++)
        for (int n = 0; n < size - i; n++)
            if (nums[i] > nums[i + 1])
                swap(&nums[i], &nums[i + 1]);
}
int main()
{
    printf("请先输入您要输入的数组长度\n");
    int size;
    scanf_s("%d", &size);
    int* p = (int*)malloc(size * sizeof(int));
    printf("请输入您要输入的一组数\n");
    for (int i = 0; i < size; i++)
    {
        scanf_s("%d", p);
        p++;
    }
    rank(p, size);
    for (int i = 0; i < size; i++)
    {
        printf("%d ", *p);
        p++;
    }
    return 0;
}
