/* [Challenge] You have a movie database (2 films are enough). You know from every movie -Names -Publishing year - ranking The user wants to output the database in a list and specify the format. The variables name, year, rank are given in angle brackets. He can freely choose additional characters. Example with database The Lord of the Rings, 2001, 8.7 Tootsie, 1982, 3.5 user input: *** *** *** **** output: *** The Lord of the Rings *** 8.7 *** 2001 *** *** Tootsie *** 3.5 *** 1982 *** user input: >>>>>>>>>> output: The Lord of the Rings >>>>>>>>>> 2001 Tootsie >>>>>>>>>> 1982 If the user input is not valid, give a hint and print the list as you like. */ #include #include #include using namespace std; class DBMovie { public: string name; int year; double rating; DBMovie(string,int,double); }; DBMovie::DBMovie(string str,int i,double d):name(str),year(i),rating(d){} const string stryear = ""; const int intyear = stryear.size(); const string strname = ""; const int intname = strname.size(); const string strrating = ""; const int intrating = strrating.size(); class input { public: string seperator_l; string seperator; string seperator_r; vector vecToDisplay; bool IsValid; input(const string& s); void printDB(vector& vecDB); }; input::input(const string& s) { IsValid = false; size_t find_name,find_year,find_rating; find_name = s.find(strname); find_year = s.find(stryear); find_rating = s.find(strrating); if(find_name != string::npos) { vecToDisplay.push_back(strname); } if(find_year != string::npos) { vecToDisplay.push_back(stryear); } if(find_rating != string::npos) { vecToDisplay.push_back(strrating); } sort(vecToDisplay.begin(),vecToDisplay.end()); int intCntField = vecToDisplay.size(); if(intCntField<1) { IsValid = false; return; } int start1 = 0; int end1 = 0; int start2 = 0; int end2 = 0; int c = 0; string strField; strField = vecToDisplay[c]; if(strField == strname) { start1 = find_name; end1 = start1 + intname ; } if(strField == strrating) { start1 = find_rating; end1 = start1 + intname ; } if(strField == stryear) { start1 = find_year; end1 = start1 + intname ; } if(start1>0) { seperator_l = s.substr(0,start1); } else { seperator_l = ""; } seperator = ""; while(c& vecDB) { if(!IsValid) { cout << "Invalid input....."; cout << "Below is sample format\n"; cout << endl << strname << ":"<< stryear << ":" << strrating << endl << endl; return; } int intCntDB = vecDB.size(); int intCntField = vecToDisplay.size(); for(int iDB = 0;iDB < intCntDB;++iDB) { cout << seperator_l; for(int intField = 0;intField < intCntField;++intField) { string strField = vecToDisplay[intField]; if(strField == strname) cout << vecDB[iDB].name; if(strField == strrating) cout << vecDB[iDB].rating; if(strField == stryear) cout << vecDB[iDB].year; if(!(intField==intCntField-1)) cout << seperator ; } cout << seperator_r << endl <vecDB; vecDB.emplace_back("The Lord of the Rings",2001,8.7); vecDB.emplace_back("Tootsie",1982,3.5); //user input here //string s = ">>>>>>>>>> "; string s = "***||||***"; cout << s << endl << endl; // logic input objI(s); objI.printDB(vecDB); return 0; }
