Question

Im trying to extract two (int32_t) values, and place them within a char array.

int32_t version = getVersion();

if (version < 0)
{
    return;
}
else
{
    //first part of number needs to be shifted right
    int32_t major = (((version) >>16) & 0xFFFF);
    int32_t minor = ((version) & 0xFFFF);

    // need to concatenate these two values, and place a "." between them

    setVersion(...);//requires a char array, should for example be "1.1"
}

can anyone give me any advice on the best way to do this? without the use of std::strings please.
I would prefer a char array.

Thanks in advance

You can employ strstream

char v[255] = {};
{
  std::strstream vs(v, 254);
  vs << major << '.' << minor;
}
setVersion(v);
