Problems
Write a program that takes a real number in yards, converts it to centimeters (cm), and prints both the input value and the converted value rounded to the first decimal place as shown in the output example. (Note: 1 yard = 91.44 cm.)
For input, first print "yard? " and then receive a real number. Use "double" for the real number.
Example
yard? 10.1
10.1yard = 923.5cm
