难道没有#include <vector>？如果是，那就欠抽了。以下代码在gcc4.6.1和vc++9.0下都编译运行通过
 程序代码：#include <algorithm> #include <vector> using namespace std; template<typename T> bool median( const vector<T>& c, T& m ) { vector<T> temp(c); if( temp.size()%2 == 0 ) return false; if( temp.size() == 1 ) { m = c[0]; return true; } sort( temp.begin(), temp.end() ); typename vector<T>::size_type index = temp.size()/2; if(temp[index]>=temp[index-1] && temp[index]<=temp[index+1]) { m = temp[index]; return true; } return false; } #include <iostream> int main() { vector<int> c; c.push_back( 4 ); c.push_back( 3 ); c.push_back( 5 ); int m; median( c, m ); cout << m << endl; return 0; } |
Compiling...

代码如下:
程序代码：//median.cpp
template<typename T>
bool median(const vector<T>&c,T&m)
{
vector<T> temp(c);
if(temp.size()%2==0)
return false;
sort(temp.begin(),temp.end());
vector<T>::size_type index=temp.size()/2;
if(temp[index]>temp[index-1]&&temp[index]<temp[index-1])
{
m=temp[index];
return true;
}
else
return false;
}
template<typename T>
bool median(const vector<T>&c,T&m)
{
vector<T> temp(c);
if(temp.size()%2==0)
return false;
sort(temp.begin(),temp.end());
vector<T>::size_type index=temp.size()/2;
