C++Test Review Design and implement a class dayType that implements the day of theweek in a program. The class dayType should store the day, such as Sunfor Sunday. The program should be able to perform the following operationson an object of type dayType:Set the day.a.b.Print the day.c.Return the day.d.Return the next day.Return the previous day.е.Calculate and return the day by adding certain days to the current day.For example, if the current day is Monday and we add 4 days, the day tobe returned is Friday. Similarly, if today is Tuesday and we add 13 days,the day to be returned is Monday.Add the appropriate constructors.f.g.Write the definitions of the functions to implement the operations for theclass dayType as defined in Programming Exercise 5. Also, writeprogram to test various operations on this class.aCode for dayType class:class dayType{public:static string weekDays[7];void print() const;string nextDavl) const;string prevRavl) const;void addDaylint nDavs);void setDay(string d);string getDayl) const;davTvpel);davTYpe(string d);private:string weekDay;};

C++Program code: #include <iostream>#include <string>#include <iomanip>using namespace std; class dayType{ public: static string weekDays[7]; void print() const; string nextDay() const; string prevDay() const; void addDay(int nDays); void setDay(string d); string getDay()const; dayType(); dayType(string d); private: string weekDay;};string dayType::weekDays[7] = {"Sun", "Mon", "Tue","Wed", "Thu", "Fri", "Sat"};void dayType::setDay(string d){ weekDay = d;}string dayType::nextDay() const{ if(weekDay=="Sun") return "Mon"; if(weekDay=="Mon") return "Tue"; if(weekDay=="Tue") return "Wed"; if(weekDay=="Wed") return "Thu"; if(weekDay=="Thu") return "Fri"; if(weekDay=="Fri") return "Sat"; if(weekDay=="Sat") return "Sun"; }string dayType::prevDay() const{ if(weekDay=="Sun") return "Sat"; if(weekDay=="Mon") return "Sun"; if(weekDay=="Tue") return "Mon"; if(weekDay=="Wed") return "Tue"; if(weekDay=="Thu") return "Wed"; if(weekDay=="Fri") return "Thu"; if(weekDay=="Sat") return "Fri"; }void dayType::print() const{ cout<<weekDay;}void dayType::addDay(int nDays){ int day; if(weekDay=="Sun") day=0; if(weekDay=="Mon") day=1; if(weekDay=="Tue") day=2; if(weekDay=="Wed") day=3; if(weekDay=="Thu") day=4; if(weekDay=="Fri") day=5; if(weekDay=="Sat") day=6; day+=nDays; cout<<weekDays[day];} string dayType::getDay() const{ return weekDay;}dayType::dayType(){ weekDay="Sun";}dayType::dayType(string d){ weekDay = d;}int main(){ dayType d; dayType d1("Mon"); d1.addDay(4); cout<<d1.prevDay(); cout<<d1.nextDay(); d1.print();}Screenshot: Output:
