templates c++

template  < typename  T > 
inline  T  max ( T  a ,  T  b )  { 
    return  a  >  b  ?  a  :  b ; 
}

int  main () 
{ 
    // Isso chamará max <int> por dedução implícita do argumento. 
    std :: cout  <<  max ( 3 ,  7 )  <<  std :: endl ;

    // Isso chamará max <double> por dedução implícita do argumento. 
    std :: cout  <<  max ( 3.0 ,  7.0 )  <<  std :: endl ;

    // Isso depende do compilador. Alguns compiladores lidam com isso definindo uma 
    função de 
    modelo // como double max <double> (double a, double b) ;, enquanto em alguns compiladores // precisamos convertê-lo explicitamente, como std :: cout << max <double> (3,7,0); 
    std :: cout  <<  max ( 3 ,  7.0 )  <<  std :: endl ; 
    std :: cout  <<  max < double > ( 3 ,  7.0 )  <<  std :: endl ; 
    return  0 ;

c++ template

// sequence template
#include <iostream>
using namespace std;

template <class T, int N>
class mysequence {
    T memblock [N];
  public:
    void setmember (int x, T value);
    T getmember (int x);
};

template <class T, int N>
void mysequence<T,N>::setmember (int x, T value) {
  memblock[x]=value;
}

template <class T, int N>
T mysequence<T,N>::getmember (int x) {
  return memblock[x];
}

int main () {
  mysequence <int,5> myints;
  mysequence <double,5> myfloats;
  myints.setmember (0,100);
  myfloats.setmember (3,3.1416);
  cout << myints.getmember(0) << 'n';
  cout << myfloats.getmember(3) << 'n';
  return 0;
}
