Question

'ps' : cannot convert parameter 3 from 'int (int,int)' to 'int (__cdecl *)(void)'是为什么

#include <stdio.h>
void main()
{
int max(int x,int y);
int min(int x,int y);
int add(int x,int y);

void ps(int x,int y,int(*f)() );
int a,b;
printf("请输入a和b");
scanf("%d %d",&a,&b);

printf("max=");
ps(a,b,max);

printf("min=");
ps(a,b,min);

printf("sum=");
ps(a,b,add);
}

int max(int x,int y)
{
int z;

if(x>y)
z=x;
else
z=y;

return z;
}

int min(int x,int y)
{
int z;
if(x<y)
z=x;
else
z=y;

return z;
}

int add(int x,int y)
{
int z;
z=x+y;
return z;
}

void ps(int x,int y,int(*f)() )
{
int a;
a=(*f)(x,y);
printf("%d",a);

}

Answer 1

int(*f)()应该改成int(*f)(int,int)

Answer 2

形参和实参类型不匹配
