Question

I have been using the following vector initialization with values in Code::Blocks and MingW compiler:

vector v0 {1,2,3,4};

A

Answer 1

I have defined a macro :

#define init_vector(type, name, ...)\
    const type _init_vector_##name[] { __VA_ARGS__ };\
    vector name(_init_vector_##name, _init_vector_##name + _countof(_init_vector_##name))

and use like this :

init_vector(string, spell, "zero", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine" );

for(auto &a : spell)
  std::cout<< a <<" ";
