What is the easiest way to initialize a std::vector with hardcoded elements?

Question

I can create an array and initialize it like this:

int a[] = {10, 20, 30};

How do I create a std::vector and initialize it sim

Answer 1

I build my own solution using va_arg. This solution is C++98 compliant.

#include 
#include 
#include 

template 
std::vector initVector (int len, ...)
{
  std::vector v;
  va_list vl;
  va_start(vl, len);
  for (int i = 0; i < len; ++i)
    v.push_back(va_arg(vl, T));
  va_end(vl);
  return v;
}

int main ()
{
  std::vector v = initVector (7,702,422,631,834,892,104,772);
  for (std::vector::const_iterator it = v.begin() ; it != v.end(); ++it)
    std::cout << *it << std::endl;
  return 0;
}
