c++ - Best way to program such things " writing the code " :: Qt -

can guys me these questions , give opinion.

1- let's want create window maybe calculate " window " ok if write of stuff in constructor instead of creating function me call in constrictor ? or better approach.

2- let's have array or qvector or , maybe +30 elements , elements meant constant maybe holding subjects names "i want insert names not user", considered bad initialize this:

s[0]=".." s[1]="...." 

since can't use loop because names change.

i tell any function should small, not constructor. this might help.

consider specifying these values in external configuration file, load (i.e. parse) when application starts. is, instead of having tons of statements like

s[0] = "john doe" s[1] = "jane doe // ... 

put names in file, names.cfg, , fill in qvector this:

std::ifstream in{"names.cfg"};  qvector<std::string> names; std::string current_name;  while (std::getline(in, current_name))     names.push_back(current_name); 

disclaimer: i'm no qt expert, think use of qvector valid.
