Variables and Constant

Constants and variables are widely used in mathematical equations and expressions. They are also commonly found in the domain of programming, where each language has its own way to differentiate between a constant and a variable. Since they have all sorts of applications, knowing their differences is a good place to start.

Double length is read from input and area is the square of length. Perform the following tasks:
• Output length with a maximum of eight digits, showing the decimal point and any trailing Os. Then, output " ".
Output area in fixed-point notation with a maximum of five digits in the fraction. Then, output " ".
Output area in scientific notation with a maximum of five digits in the fraction. End with a newline.
Ex: If the input is 6.75, then the output is:
6.7500000 45.56250 4.55625e+01
Note: cout << showpoint shows the decimal point and any trailing Os even when the fraction (after the decimal point) is zero.
