大家帮小弟我看看哪错了?解决立刻结!

大家帮我看看哪错了?解决立刻结!!
问题在注释的地方说明
#include <iostream>
#include "d_random.h "// "d_random.h "的代码没贴出...但不影响大家看程序..
using   namespace   std;

template <typename   T>
class   Node{
public:
T   Nodevalue;
Node <T>   *next;
Node():next(null){};
Node(const   T&value,Node <T>   *nextNode):Nodevalue(value),next(nextNode){};
};

template <typename   T>
void   writeLikelistValue(Node <T> *   front){
Node <T>   *cur   =   front;
while(cur!=NULL){
cout < <cur-> Nodevalue < < "   ";
cur   =   cur-> next;
}
}

template <typename   T>
void   eraseValue(Node <T>   *front,const   T&   target){
Node <T>   *current   =   front,*prev   =   NULL;
bool   hasfind   =   false;
while(current   !=   NULL   &&   !hasfind){
if(current-> Nodevalue   ==   target){
if(prev   ==   NULL)
front   =   front-> next;
else
prev-> next   =   current-> next;
delete   current;
hasfind   =   true;
}
else{
prev   =   current;
current   =   current-> next;
}
}
}


template <typename   T>
Node <T> *   getMax(Node <T>   *   front){
Node <T>   *current   =   front,*max   =   front;
while(current   !=   NULL){
if(current-> Nodevalue   >   max-> Nodevalue){
max   =current;
current   =   current-> next;
}
}
return   max;
}

int   main(){
int   size;
randomNumber   ran;
Node <int>   *front   =   NULL,*p;
cout < < "please   input   Node   size: " < <endl;
cin> > size;
for(int   i   =   0;i   <   size;i++)
front   =   new   Node <int> (ran.random(100),front);
cout < < "original   Node   is: " < <endl;
writeLikelistValue(front);
cout < <endl;
cout < < "sorted   Node   is: " < <endl;
while(front   !=   NULL){//就是这里开始有问题了....什么也输不出了...
p   =   getMax(front);
cout < <p-> Nodevalue < < "   ";
eraseValue(front,p-> Nodevalue);
}
return   0;
}







------解决方案--------------------
template <typename T>
Node <T> * getMax(Node <T> * front){
Node <T> *current = front,*max = front;
while(current != NULL){
if(current-> Nodevalue > max-> Nodevalue){
max =current;
}
current = current-> next;

}
return max;
}

说来所去，还是基础问题
修改两个地方：

(1)
template <typename T>
void eraseValue(Node <T> *front,const T& target){
Node <T> *current = front,*prev = NULL;
改为:
template <typename T>
void eraseValue(Node <T> *&front,const T& target){
Node <T> *current = front,*prev = NULL;
