Complex numbers can be represented in polar form like M<θ. Where M is the magnitude and

θ is the angle in degrees. Use the concept of operator overloading to write a class in which the

user will enter the magnitudes and angles (in degrees) for two complex numbers. And then

the program will add, subtract, divide or multiply them and display the result in polar form.

1.Write a procedure that displays the number of countries in a given region (prompt for value) whose highest elevations exceed a given value (prompt for value). The procedure should accept two formal parameters, one for a region_id and the other for an elevation value for comparison. Use DBMS_OUTPUT.PUT_LINE to display the results in a message. Test your procedure using the value 5 for the region_id and 2000 for the highest evaluation

Write a Python program using lists, function and loops that will prompt a user to enter a temperature as an integer. Your program will print "it is hot" if the temperature is over 100, "it is cold" if the temperature is under 60, and "it is just right" if the temperature is between 61 and 99 inclusive. The program continues to ask for temperatures, and evaluates them as above, until the user enters a temperature of 0 (to exit the program). An example of the anticipated program is shown below: Please enter a temperature: 95 It is just right. Please enter a temperature: 110 It is hot. Please enter a temperature: 32 It is cold. Please enter a temperature: 0 Good bye!
