Question

Double length is read from input and area is the square of length. Perform the following tasks -

A. Output length with a maximum of seven digits, showing the decimal point and any traling Os. Then, output *. -
B. Output area an fixed point notation with a maximum of three digits in the fraction. Then, output ". -
C. Output area in scientific notation with a maximum of three digits in the fraction End with a newine
Ex. If the input is 27625 , then the output is
27.62500.763.1406257.631406e+02

Answer 1

To display a double length and its square area, adhere to specific formatting rules for outputting the length and area in fixed-point and scientific notation while considering significant figures.

Step-by-step explanation:

When dealing with a double length read from input and calculating the area as the square of length, we need to follow specific notation requirements for output:

1. A. Output length with a maximum of seven digits, showing the decimal and any trailing zeros. For example, if the input is 27625, after dividing by 1000 (to get the double length), the output length would be formatted to 27.62500*.
2. B. Output the calculated area in fixed-point notation with a maximum of three digits in the fraction, followed by a period. For instance, if the area is 763.140625, it would be represented as 763.141.
3. C. Output the same area in scientific notation with a maximum of three digits in the fraction, concluding with a newline. The previous area example would be shown as 7.631×10².
   

It is important to follow the rules of significant figures and unit conversions when performing these calculations to ensure the accuracy and significance of the results.
