3.Writeprogram codesusing forloop of the followingquestions. The code should be written incomplete JavaScript format. Show thedry run. a)Accept a number from the user, check if the number is a prime number and display an appropriate message. For example, if the user inputs 7, then display the message, “7 is a prime number”, otherwise if the user inputs 8, then display the message, “8 is not a prime number”.(Prime numberis a number whose only factors are1 and the number itself.)b)Display the factorialand the first fivemultiples of 5usinga singlefor loop.(Factorial is the product of an integer and all thepositiveintegers lesser thanit. Eg. 5!=1*2*3*4*5=120)

Consider the following statements: #include #include class temporary { private: string description; double first; double second; public: temporary(string = "", double = 0.0, double = 0.0); void set(string, double, double); double manipulate(); void get(string& , double& , double& ); void setdescription(string); void setfirst(double); void setsecond(double); }; write the definition of the member function set() so that the instance variables are set according to the parameters. write the definition of the constructor so that it initializes the instance variables using the function set() write the definition of the member function manipulate() that returns a decimal number (double) as follows: if the value of description is "rectangle", it returns first * second if the value of description is "circle" it returns the area of a circle with radius first if the value of description is "cylinder" it returns the volume of a cylinder with radius first and height second. hint: the volume of a cylinder is simply the area of the circle at the base times the height. if the value of description is "sphere" it returns the volume of the sphere with radius first. otherwise it returns -1.0;
