(Modify) Rewrite the following program to use the named constant FACTOR in place of the expression (5.0/9.0) used in the program:

#include using namespace std;int main(){double fahren, celsius;cout << "Enter a temperature in degrees Fahrenheit: ";cin >> fahren;celsius = (5.0/9.0) * (fahren - 32.0);cout << "The equivalent Celsius temperature is "<< celsius << endl;return 0;}
