通过指针更改变量

#include<stdio.h>
void getMinOrMax(int a[], int length, int *min, int *max);
int main()
{
    int a[]={12,15,78,62,4,67,3,16,46,24,};
    int min, max,length;
    length = sizeof(a) / sizeof(a[0]);
    getMinOrMax(a, length, &min, &max);
    printf("min = %d,max = %d", min, max);
    return 0;
}
void getMinOrMax(int a[],int length,int *min,int *max)
{
    *min = *max = a[0];
    for (int i = 1; i < length;i++)
    {
        if(*min>a[i])
            *min = a[i];
        if(*max<a[i])
            *max = a[i];
    }
