   10. exercises
       1. 1.- Input two numbers and work out their sum, average and sum of the squares of the numbers.
       2. 2.- Write a program to read a "float" representing a number of degrees Celsius, and print as a "float" the equivalent temperature in degrees Fahrenheit. Print your results in a form such as 100.0 degrees Celsius converts to 212.0 degrees Fahrenheit.
       3. 3.- Write a program to read a number of units of length (a float) and print out the area of a circle of that radius. Assume that the value of pi is 3.14159 (an appropriate declaration will be given you by ceilidh - select setup).
       4. 4.- Given as input a floating (real) number of centimeters, print out the equivalent number of feet (integer) and inches (floating, 1 decimal), with the inches given to an accuracy of one decimal place. Assume 2.54 centimeters per inch, and 12 inches per foot. If the input value is 333.3, the output format should be: 333.3 centimeters is 10 feet 11.2 inches.
       5. 5.- Given as input an integer number of seconds, print as output the equivalent time in hours, minutes and seconds. Recommended output format is something like 7322 seconds is equivalent to 2 hours 2 minutes 2 seconds.
