返回指针的函数

#include <stdio.h>
int *max(int *x, int *y)
{
    int *t;
    if(*x > *y)
        t = x;
    else
        t = y;
    return t;
}
int main()
{
    int  a, b, *p;
    scanf("%d %d", &a, &b);
    p = max(&a, &b);
    printf("max = %d \n", *p);
    return 0;
}

#include <stdio.h>
int *max(int *x, int *y)
{
    int t;
    if(*x > *y)
        t = *x;
    else
        t = *y;
    return &t;
}
int main()
{
    int  a, b, *p;
    scanf("%d %d", &a, &b);
    p = max(&a, &b);
    printf("max = %d \n", *p);
    return 0;
