Remove NaNs and Sort by size You are going to sort the planets by size in order of largest to smallest. a. Remove NaNs - you will notice that some values in the rad array are filled with NaN instead of a value. This is because some exoplanets do not have data for their radius. The first step of this part is to remove all the data (rad and names_pl) that does not have available radius data. Save indices of where the NaNs are located to the variable named remove.
b. Sort the planets by size - The final step of this part is to sort the planets by their size from largest to smallest. You must sort only the data without the NaNs in it, so make sure to remove them first. Then you will use the built in function sort to sort from largest to smallest (save the sorted radii to array with variable name rad_sort). Save the indices of the sort to the array with variable name ind_sort. Save the names in sorted order to the variable name names_pl_sorted. Once you have sorted, print out the top five planets exactly like this (don't have any typos):

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;
