帮我看看这个指针函数错在哪儿？

seablue

[php]
#include <stdio.h>
main()
{ int x, y;
  int max(int,int);
  int min(int,int);
  int sum(int,int);
  int process(x, y, (int *fun)(int,int));
  printf("Input two number:\n");
  scanf("%d %d", x, y);
  printf("max of input is:%d\",process(x, y, max));
}

int max(int a, int b)
{ if (a > b)return a;
  else return b;
}

int min(int a, int b)
{ if (a < b)return a;
  else return b;
}

int sum(int a, int b)
{ return (a + b);}
[/php]
出错：

1. 
   
2. [linuxer@mydesktop bmp]$ gcc -o ttt.o ttt.c
   
3. ttt.c: In function `main':
   
4. ttt.c:7: parse error before '(' token
   
5. ttt.c:7: `process' declared as function returning a function
   
6. ttt.c: In function `process':
   
7. ttt.c:7: parse error before ')' token
   
8. ttt.c:10:10: warning: multi-line string literals are deprecated
   
9. ttt.c:10:10: missing terminating " character
   
10. ttt.c:10:10: possible start of unterminated string literal

1.
[php] int process(x, y, (int *fun)(int,int));
//这个函数这样定义：
int process(int, int, int fun(int,int));

//要记得写函数体：
int process(int x, int y, int fun(int,int))
{
  return fun(x,y);
}
[/php]
2.
[php] scanf("%d %d", x, y);
//这个调用有错，应改为：
scanf("%d %d", &x, &y);
[/php]
3.
[php]
printf("max of input is : %d\",process(x, y, max));
//这里是粗心吧？？改成：
printf("max of input is : %d\n",process(x, y, max));
//仔细看看有什么不同。

短短几行代码我就错了这么多，真是遗笑大方了:p
看来路还好长。。。
