A.) generate scaffolding to create database for your application. develop all the entities identified in assignment #2. add any additional that may be identified later. b.) add data validation rules to the models that are appropriate for your application and data. c.) create links for each scaffold in the header section. part 2: application updates [30 points] a.) add two additional views to the "home" controller you created in assignment #1. b.) the two views should be named as “privacy" and "". c.) link the two newly created views in the footer section. hint: you would need to modify the “home" controller definition and create “privacy. html. erb" and “.html. erb" files in appropriate locations.

Which of these is most responsible for differences between the twentieth century to the twenty-first century?

Writing a modular program in visual c++. i am new to this and not sure what i am missing. i am getting the following error: baddate. cpp: in function ‘int main()’: baddate. cpp: 50: 3: error: ‘else’ without a previous ‘if’elsehere are the instructions and code: writing a modular program in c++in this lab, you add the input and output statements to a partially completed c++ program. when completed, the user should be able to enter a year, a month, and a day. the program then determines if the date is valid. valid years are those that are greater than 0, valid months include the values 1 through 12, and valid days include the values 1 through 31.notice that variables have been declared for you. write the simulated housekeeping() function that contains the prompts and input statements to retrieve a year, a month, and a day from the user. include the output statements in the simulated endofjob() function. the format of the output is as follows: month/day/year is a valid date. ormonth/day/year is an invalid date. execute the program entering the following date: month = 5, day = 32, year = 2014. record the output of this program. execute the program entering the following date: month = 9, day = 21, year = 2002. record the output of this /* program name: baddate. cppfunction: this program determines if a date entered by the user is valid. input: interactiveoutput: valid date is printed or user is alerted that an invalid date was entered*/#include bool validatedate(int, int, int); using namespace std; int main(){// declare variablesint year; int month; int day; const int min_year = 0, min_month = 1, max_month = 12, min_day = 1, max_day = 31; bool validdate = true; // this is the work of the housekeeping() method// get the year, then the month, then the daycout< < "enter the year"< > year; cout< < "enter the month"< > month; cout< < "enter the day"< > day; // this is the work of the detailloop() method// check to be sure date is validif(year < = min_year) // invalid yearvaliddate = false; else if (month < min_month || month > max_month) // invalid monthvaliddate = false; else if (day < min_day || day > max_day) // invalid dayvaliddate = false; // this is the work of the endofjob() method// test to see if date is valid and output date and whether it is valid or notif(validdate == true); {// output statementcout<
