可以帮助我看看这个代码两个错误在哪里吗

Question

#include<stdio.h>
int main()
{
int max(int,int);
int(*p)(int,int);
int(*q)(int,int);
int a,b,c,d;
p=max;
q=min;
printf("please enter a and b:\n");
scanf("%d,%d",&a,&b);
c=(*p)(a,b);
printf("The max is %d",c);
d=(*q)(a,b);
printf("The min is %d",d);
return 0;

}

int max(int x,int y)
{
    int z;
    if(x>y)
        z=x;
    else
        z=y;
    return(z);
}

int min(int m,int n)
{
    int o;
    if(m<n)
        o=m;
    else
        o=n;
    return(o);
}

Answer 1

min函数你没有申明
