Question

编写一个函数，要求用指向指针的方法対n个整数排序并输出。用c语言编写

Answer 1

#include <STDIO.H>
#define N 10

int Px(int num[])
{
int i, j;
for ( i = 0; i < N; i++ )
for ( j = 0; j < N - 1 - i; j++ )
{
if (num[j] < num[j + 1])
{
int temp;
temp = num[j];
num[j] = num[j + 1];
num[j + 1] = temp;
}
}
}

main()
{
int num[N], i;
printf ("Please input the numbers: ");
for ( i = 0; i < N; i++ )
{
scanf ("%d", &num[i]);
}
Px(&num);
for ( i = 0; i < N; i++ )
{
printf ("%d ", num[i]);
}
}
