The area of a rectangle is its length times its height. Write a C program that inputs two floating point numbers from the keyboard that represent the length and the height of a rectangle. Your program should output the area of the rectangle. If you use the type double to declare your variables, you will need to use the %lf format code with scan f. See the back-cover pages of your book. If you use the type float to declare your variables, you will need to use the %f format code with scan f. The function print f, on the other hand, uses %f for both double and float types. These little tidbits are in your textbook
