下面是编译时产生的错误：
D:\c+++\MSDev98\MyProjects\二叉树\123.cpp(25) : error C2601: 'PrintElement' : local function definitions are illegal
D:\c+++\MSDev98\MyProjects\二叉树\123.cpp(29) : error C2601: 'PreOrderTraverse' : local function definitions are illegal
D:\c+++\MSDev98\MyProjects\二叉树\123.cpp(40) : error C2601: 'main' : local function definitions are illegal
D:\c+++\MSDev98\MyProjects\二叉树\123.cpp(50) : fatal error C1004: unexpected end of file found
怎么老是说函数定义不合法呢？再是函数指针做函数参数怎么样？
请大虾们帮帮忙..

typedef fnpoint (void) p*(double,....);
这么用就简洁了

   }

    return 1;
