Hello all,

can anyone tell me how can i make the following code to work fine in MVS and GNU compiler? This code will work only for MVS. GNU compiler will generate a building error.

#include <iostream>
#include <vector>
using namespace std; 

template<class T>
const vector<T>&
operator*=(vector<T>& obj1, const T typeVal)
{                              
  for (unsigned i = 0; i < obj1.size(); i++)
    obj1[i] *= typeVal; 

  return obj1;
} 

template<class T>
const vector<T>
operator*(const vector<T>& obj1, const T typeVal)
{
  return (vector<T>(obj1) *= typeVal);
} 

template<class T>
const vector<T>
operator*(const T typeVal, const vector<T>& obj1)
{
  return (obj1*typeVal);
}

int main()
{
  vector<double> x(3,4);
  vector<double> d = x*2.0;
  cout << d[0] << " " << d[1] << " " << d[2] << endl;
  return 0;
}

What error do you get?

GNU compiler will produce an error because there is no *= that matches the overloaded operators in std::vector class.

OK, so instead of A*=B, use A=A*B
