i have following code:

void module_books::show_item(int n, table<book> b) {   cout<<"title:         "<<b[n]->title<<"\n";   cout<<"author:        "<<b[n]->author<<"\n";   cout<<"issue:         "<<"no. "<<b[n]->issueno<<". "<<b[n]->city<<", "<<b[n]->publisher<<", "<<b[n]->year<<"\n";   cout<<"isbn:          "<<b[n]->isbn<<"\n";   cout<<"pages count:   "<<b[n]->pages<<"\n";   cout<<"information:   loan count: "<<b[n]->outcount<<". ";   if(b[n]->damaged) cout<<"damaged ";   if(b[n]->out) cout<<"loaned";   cout<<"\n\n"; }  int module_books::add_item(table<book> &b) {    int _year, _issueno, _pages;   bool _damaged=false;   string _title, _author, _isbn, _publisher, _city, stmp;    cout<<"you're adding new book list.\nfill in following fields:\n\n";   cout<<"title:               "; getline(cin,_title);   cout<<"author:              "; getline(cin,_author);   cout<<"issue no:            "; cin>>_issueno; cin.ignore(std::numeric_limits<std::streamsize>::max(), l'\n');   cout<<"issued in (city):    "; getline(cin,_city);   cout<<"issuer:              "; getline(cin,_publisher);   cout<<"issued in (year):    "; cin>>_year; cin.ignore(std::numeric_limits<std::streamsize>::max(), l'\n');   cout<<"isbn:                "; getline(cin,_isbn);   cout<<"pages count:         "; cin>>_pages;   cout<<"is damaged? (y/n):   "; cin>>stmp; cin.ignore(std::numeric_limits<std::streamsize>::max(), l'\n');   if(stmp=="y" || stmp=="yes" || stmp=="y" || stmp=="yes" || stmp=="yes") _damaged=true;    int n=b.size();    b.push_back(book(_title,_author,_publisher,_city,_isbn,_year,_issueno,_pages,_damaged));    cout<<"\nthe book has been added:\n\n";   show_item(n,b);   cout<<"\nreturning\n";   return n; }

book struct member variables. table struct template, works stl vector (i'm not allowed use vector, had write own template, @ moment it's using static array t ar[100]).

the problem message book has been added , show_item function prints data, no "returning" message.

i tried setting breakpoints show_table function reaches ending }, program never gets "returning" message.

what might wrong code? i'm using 32-bit qtcreator mingw. os 64-bit win8.1 if help...
