Write a program to compute the total power generated by a klink circuits, where the n is entered by the user, for each circuit ask for the input phase angle, compute the power and add that power to the total, each time you ask the user to enter the phrase angle, if the user does not enter a number between 0 and 90 display an error message and ask them again until they enter a valid if the entry is not valid, then do not compute the power and do not count that as one of the n circuits, also check for a positive number for the n - the number for circuits. display the total power(and do not display the cumulative total after each circuit)

the power generated by a klink circuits
p=kcos(aπ/180)

where
p = power(killowats, k w)
k = klinks constant (5/7)
a = phase angle (in degrees)
π = pi (3.

Define a class named movie. include private fields for the title, year, and name of the director. include three public functions withprototypes void movie: : settitle(cstring); , voidmovie: : setyear(int); , void movie: : setdirector(string); . includeanother function that displays all the information about a movie. write a main() function that declares a movie object namedmyfavoritemovie. set and display the object's fields. this is what i have but know its wrong since it will notcompile: #include#includeusing namespace std; //class declarationclass movie{private: string movietitle ; string movieyear; string directorname; public: void settitle(string title); void setyear(string year); void setdirector(string director); void displayinfo(); }; //class implementationvoid movie: : settitle(string title){ movietitle = title; cout< < "what is the title of themovie? "< > temp; myfavoritemovie. settitle(temp); cout< < "enter movie year"< > temp; myfavoritemovie. setyear(temp); cout< < "enter director'sname"< > temp; myfavoritemovie. setdirector(temp); //display all the data myfavoritemovie. displayinfo(); system("pause"); return 0; this code is not entirely mine someone on cramster edited my firstcode but then i try manipulating the new code and i still get acompile error message : \documents\visual studio 2008\projects\movie\movie\movie. cpp(46) : error c2679: binary '< < ' : no operator found which takes aright-hand operand of type 'std: : string' (or there is no acceptableconversion)c: \program files (x86)\microsoft visual studio9.0\vc\include\ostream(653): could be'std: : basic_ostream< _elem,_traits> & std: : operator< < > (std: : basic_ostream< _elem,_traits> & ,const char *)w
