2. When both the diene and dienophile are unsymmetrical, then regiochemistry becomes an issue. In this case, it is helpful to remember that when you number the diene and dienophile, that carbon 1 of the diene can either attach to carbon 6 or to carbon 5 of the dienophile: 1 1 2 4 2 6 2 5 1 5 3 3 5 3 6 4 4 In on top of this, you still need to think about the different possible...

Write a program that contains a main function, a “double custom_operator_function(int op_type, double x, double y)”, a “double min(double,double)”, a double max(double x,double y), and a double pow(double x, int y). The main function is used to call the custom operator function. Next, the custom operator function calls the min/max/pow functions based on the op_type. From the main, call the custom operator function with the three inputs 1/-3/5, 2/4/5, and 3/4/5. Print the result of each input to screen. i)...
