我对这段代码有问题，但不知道为什么...

import inspect
inspect.getsource(min)

错误是：

Traceback (most recent call last):
  File "<pyshell#1>", line 1, in <module>
    inspect.getsource(min)
  File "C:\Python33\lib\inspect.py", line 726, in getsource
    lines, lnum = getsourcelines(object)
  File "C:\Python33\lib\inspect.py", line 715, in getsourcelines
    lines, lnum = findsource(object)
  File "C:\Python33\lib\inspect.py", line 551, in findsource
    file = getfile(object)
  File "C:\Python33\lib\inspect.py", line 435, in getfile
    'function, traceback, frame, or code object'.format(object))
TypeError: <built-in function min> is not a module, class, method, function, traceback, frame,or code object

这是一个程序,找到一个字符串中最长的单词,但我有一个问题.编译器说我不能比较一个指向整数的指针!但我比较一个字符串指针的char指针

#include <string.h>
#include <string>
#include <iostream>
using namespace std;

string longest(char * a)
{
    int count=0;
    int finalcount=0;
    string longs="";
    string longest;  
    int lena=strlen(a);
    for(int i=0;i<lena;i++)
    {
        if(*a==" ")
        {
            if(count>=finalcount)   
            {
                finalcount=count;
                longest=longs;
            }
            count=0;
            longs="";
        }
        else{*a++;count++;longs+=*a;}
    }
    return longest;
}
int main()
{
    char a[]="which is the longest";
    cout<<longest(a);
    return 0;
}
