The program should ask the user to type in his or her height in two parts: first the height in feet and then the inches part for the height. (A person can say that his or her height is, for example, 5 feet and 9 inches. That would be 30.48 * 5 + 2.54 * 9 centimeters. There can be thus two separate input statements in the program. After the program has received the feet and the inches, it should calculate the corresponding value in centimeters and print it to the screen. You can input the values to int variables but the calculation results could be stored in variables of type double.
